Toradex CE Libraries Release

Description: Wait for CAN_Read before calling CAN_Close

Description: Adjust number of buffers for the rpmsg protocol on the i.MX7

Description: On Colibri iMX7, SODIMM pin 77 cannot be accessed using the Gpio Library.

Workaround: Write your code to use GPIO 176, which is identical to SODIMM 77 for Colibri iMX7.

Description: The I2C library tries to "unlock" I2C bus if a slave device is not releasing the SDA signal, this may happen if the module is reset in the middle of an I2C transaction when the slave device has control of SDA line.

Workaround: Issue has been fixed.

Description: A 32-bit hash is used to represent the library build number, which can be queried by calling xxx_GetVersion(). In contrast to previous library versions, the build number is not increasing for newer library versions, but must be treated as a random 32-bit number.

Description: I2cTransaction calling through kernelCallback. Kernelcallback doesn't seems to be working from kernel driver.

Description: Large Splashscreen cannot be programmed using the UpateTool

Workaround: Use bootloader command flashsplash or Toradex Easy Installer to load the splashscreen

Description: Sending zero-length CAN messages can cause an error message "Division by zero".

Description: The generic Spi_Read and Spi_Write are not calling iMX7 platform-specific APIs.

Description: Implement a parameter istPriority to configure the priority of the interrupt thread, which reads messages from the MCP2515 controller.

Description: From Library version 2.1, no I2C Bus reset is sent anymore. If there is a malfunctioning device or a device was in the middle of a transfer and a system reset was done which the device does not see, I2C communication could be malfunctioning

Description: Add documentation about how to read/write data from/to the ConfigBlock, e.g. Hardware ID and version, MAC address, user data.

Description: The Linker reports errors about mismatched versions of compiler / linker, when building an application in RELEASE configuration. This is caused by an optimization "Link Time Code Generation" which we enabled for building the libraries V2.1.

Workaround: Use the Toradex CE Libraries in DEBUG configuration, or restore the old compiler which Microsoft stored at C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\ce\bin\x86_arm\KB2921525_BACKUP\

Description: When sending a CAN message with 0 length, the Toradex function @Can_Write()@ crashes with a divide by zero exception.

Description: Change the definition of xxx_GetConfigString() functions

Description: Library hits breakpoint with warning "SYS Error: .\src\config_parser.c, 434: Context Corruption" or similar. Affected libraries are SysInfo, Can, i2c and RpMsg.

Workaround: Will be solved in library package V2.3

Description: Some SOC specific functions are missing in TdxAllLibrariesDll.cs. One is for example CAN functions for IMX6.

Workaround: Use the genric functions or add the missing functions to the cs file on your own.

Description: The documentation of the SPI library does now list all possible clock rates for the iMX7.

Description: If the M4 firmware does not turn on the clock for the MU-A peripheral (in CCGR39), Rpmsg_Open() will hang.

Workaround: Enable the clock for MU-A before calling Rpmsg_Open()

Description: duty parameter in TegPwm_SetPwm() is mapped wrongly (0 = 0% ... 256 = 100%) but should be (0 = 0% ... 65536 = 100%)

Description: Until now CAN_Read() and CAN_Write() were serialized, so even from 2 Threads only one of the two operations is possible at the same time. Since the CAN_Read() can be used to wait for messages with a timeout all writes would be blocked for that amount of time. This behavior has now been changed so that CAN_Write() is possible even while a CAN_Read() is in progress

Description: .NET demo code was missing in the library package

Description: Documentation of Deinit function is not precise. Disabling Watchdog is possible on some platforms (e.g. T20 and T30). We will update the documentation accordingly.

Description: SPI library does not support string parameters but the strings passed in for valid int parameters are processed as integer values and this may lead to some unexpected behaviours for the library.

Workaround: Don't call Spi_SetConfigString and use Spi_SetConfigInt instead.

Description: Currently, this feature is implemented on Vybrid, only on CE7.

Description: (internal cleanup)

Description: Allow I2c_Write with 0 bytes length. NOTE: This is still not allowed on Tegra Modules

Description: Flexcan implementations of CAN_Read() and CAN_Write() have been changed to return number of messages

Description: Update Eboot.img from RAM fails

Description: The Update Library fails on calling Upd_Init(NULL)) with an exception on IMX7D modules under WEC2013.

Description: Data to send by Rpmag_Write() is defined as void*, but should be const void*

Description: Fixed by Added default pins assignments

Workaround: Configure ioScl and ioSda through I2c_SetConfigInt. Refer more documentation at Toradex_CE_Libraries.chm

Description: After calling Can_Init on the Can Library random data aborts have been seen. This has been fixed.

Description: LibDemos now also have all needed files to be opened by VS2015

Description: This has been fixed

Description: When using our libraries from .NET, calls to the functions xxx_GetConfigString() fail, due a wrong .NET wrapper definition of the function's 2nd parameter.

Description: The iMX6 clocking library supports APIs to set minimum and maximum CPU frequency. Those will work if DVFS is enabled in the image (supported from v1.3b4)

Description: On IMX6 the SPI CS pins are implemented as GPIOs. Currently it is not possible to select any other pin as CS.

Description: There is now a Config Parameter "RegisterAddrLE" to set the endianness of I2C parameter "RegisterAddr" when "RegisterAddrSize" = 16

Description: If SaveToRegistry flag is passed the parameters are actually stored in registry, but at next restart calling SPI_Init leads to a crash.

Description: On Colibri T30 library port name "I2C3" was using pins 49,51 by default, changed to use Ext15, Ext16 to make it compatible to Colibri T20. We also added new mapping for Colibri T30 "I2C4" using pins 49,51 On Colibri T20 we swapped "I2C2" and "I2C3" default mappings for the same reason to make it more compatible with Colibri T30

Description: "FrameFormat" was initially used to set the frame format used for CAN_Write() calls. Since the frame format can now be set as a flag in CAN_Write it does not make sense to have this config anymore. Instead we introduced a "FilterFrameFormat" config to filter out (remove) extended (29bit) or standard (11bit) received frames.

Description: SODIMM to GPIO mappings for SODIMM pins 36 & 38 are swapped

Description: Vybrid Gpio Library falling to run multiple instances in a process.

Description: Make the i2c library for Vybrid thread-safe

Description: If user wants to send frame with extended if he just needs to set CanMsgFlags_IDE inside canMsgFlags.

Description: Tegra I2c library: Failing to run multi-instance for multiple processes.

Description: Remove overhead code that is executed each time when sending/receiving SPI data.

Description: Update Rpmsg lib to sync with FreeRTOS Updates.

Description: TegI2c_Write() may return success (number of sent bytes) even if there was no slave replying with an ACKnowledge bit.

Description: On Vybrid and Tegra the SPI pins are already touched in the SPI_Init function also there should be no access to the on the hardware before SPI_Open. Move this to SPI_Open.

Description: FlexCan_Status returns wrongs bits to application

Description: FlexCAN Deinit generate exception on WEC2013

Description: some function parameters of the clk_imx6 library are not documented properly

Description: On Apalis T30 modules, the library port "I2C2" does not refer to the default pinout.

Workaround: To use the module's default SPI pins, use a different port name, as documented in the library help file, section i2c_teg.h.

Description: On Tegra modules, the library ports "SPI1" and "SPI2" do not refer to the default pinout.

Workaround: To use the module's default SPI pins, use a different port name, as documented in the library help file, section spi_teg.h.

Description: Several Non-SODIMM gpio pins not able to control through Gpio library

Description: Document mapping of SPI to CAN channels for Apalis T30

Description: If user wants to send RTR frame if he just needs to set CanMsgFlags_RTR inside canMsgFlags.

Description: Add support for Colibri T20/T30 and Apalis T30 modules to the SPI library.

Description: On Colibri VF50 and VF61, only the default SPI Chip select pin was working. We added support for other chip select GPIOs.

Description: Calling TegI2c_Open() after TegI2c_Close() can freeze the system.

Description: Add I2C Lib for Colibri iMX7

Description: Improve FlexCan performance on VF50 and VF61

Description: Add ADC Lib for Colibri iMX7

Description: Implement the Watchdog Library using the Hardware Watchdog feature of the Tegra modules.

Description: Add support for SPI configuration options "DmaEnable", "MasterSlave", "PackedMode", "CsPulse" and "WaitMethod"

Description: SPI library for i.mx6 does not support any string parameter so calls to Spi_SetConfigString are supposed to fail, but the generated error message is misleading.

Description: On Colibri iMX6 and Apalis iMX6, it is not possible to configure a non-standard pinout for I2C ports.

Description: If a registry path is passed to Gpio_Init(), the following call to Gpio_Open() fails.

Description: Add Support for Unpacked data

Description: Possible memory leak when calling TegI2c_Init() and TegI2c_Deinit() functions only.

Description: ClkLib: multiple instances not supported due to global variable is used

Description: Add Support for packed data

Description: CAN Library: Add Support for the MCP2515 on i.MX7

Description: For Colibri VF50 and VF61, the PWMA signal on SODIMM pin 59 shows a voltage offset of 1.7V. This is caused by a multiplexed CPU pin, which is also connected to the same SODIMM pin. The same thing is applicable to PWM_D(SODIMM pin 67) signal as well.

Workaround: Configure CPU pin PTC7 ( GPIO(52) ) as GPIO, Input for PWMA signal. Configure CPU pin PTC6 ( GPIO(51) ) as GPIO, Input for PWMD signal.

Description: The GetConfigString() function available in various libraries copies the full result string into the result buffer, even if this is more than what is defined in the maxBytes parameter.

Workaround: Make sure that the result buffer you pass to GetConfigString() is large enough.

Description: There is a constant rise in Kernel Memory consumption nk.exe when i2c_init() and i2c_deinit() is called multiple times after the boot.

Description: The library did only partially support calling RpMsg_Init() with an empty or NULL registryPath,

Workaround: Ignore debug message and make sure you don't store any configuration settings non-volatile.

Description: GPIO130 must be configured to output,high to enable Apalis pin 239 as a GPIO.

Workaround: Include code in your application to configure GPIO130.

Description: Repeated calling of xxx_Init() and xxx_Deinit() for various libraries (Gpio, I2C, etc.) was leaking some memory.

Description: Query status register of the CAN driver.

Description: On Apalis SPI1,2,3 and 5 are available, library incorrectly mapped SPI4 on the SPI5 pins.

Description: On Tegra, I2c_Write() returns an error status, instead of the number of bytes written.

Description: Support GPIO1_IO00 to GPOI1_IO15 on Colibri iMX7

Description: Parsing of configuration strings could be instable when passing invalid strings.

Description: Update lib now supports registry export/import and also flashing SPL and eboot in SPL format. Requires BSP version 1.2 and later versions.

Description: SPI on i.MX6 supports also 8 and 16 bits word lengths, but if the total length of the frame is not 32 bit aligned, the first 1,2 or 3 words are not in the correct order or contain invalid data.

Workaround: This is a driver issue,not an issue of the SPI library, but to work correctly on i.MX6 SPI library needs, at least, release 1.1 of the image.

Description: CAN through MCP2515 (on carrier board) doesn't work in library package 1.8 for Colibri VF50 and VF61.

Description: Support FreeRTOS on Colibri VF61 and provide a communication library which can be used form WinCE to transfer information between WinCE and FreeRTOS and vice-versa.

Description: FlexCAN Library doesn't return the length of received CAN message.

Description: Add support for the T20/30 modules for the PWM library using the newer API approach.

Description: Improve CAN transmit performance by allowing multiple messages to be sent at once.

Description: Introduced configuration parameter "SingleThread" which is 0 by default. By setting it to 1, the performance of the library can be significantly improved.

Description: The Spi Library for i.MX6 only supports 32bit word width.

Workaround: This is fixed in version 1.1B4, driver now supports 8-16 and 32 bits. This will require an update of both the OS and the libraries.

Description: When default values "up" or "down" are specified for the "pull" configuration parameter on i.mx6 the pin is not configured in the right way.

Workaround: Using specific values "up22k", "up47k", "up100k" or "down100k".

Description: Setting on any SpiLib config parameters could fail.

Workaround: none. Will be fixed in V1.8

Description: Reading back registry settings automatically in Gpio_Open() does not properly work.

Workaround: Use Gpio library functions to configure settings without the use of the registry, or use updated library (V1.8 and higher)

Description: Documentation only: Missing documentation for IO string options (i.e. Colibripin_*).

Description: Add support for CoProcLib on IMX7

Description: Implement MCP2515 support in the CAN library for Colibri VF50 / VF61.

Description: Implement the Watchdog Library using the Hardware Watchdog feature of the Vybrid modules.

Description: CAN functions are not available in the DLL version of the libraries (TdxAllLibrariesDll.dll)

Workaround: None - this will be fixed in library release V1.8.

Description: Implement CAN library for Colibri and Apalis i.MX6, supporting the i.MX6 internal CAN controller

Description: SetConfigString() may fail silently on an invalid string parameter, and behave like a random valid string value was passed.

Workaround: none - manually verify that you are not using unsupported configuration strings.

Description: On Colibri iMX6: Gpio_ConfigureAsGpio() properly configures both related GPIOs for SODIMM 59, 67, 93 and 99.

Description: Map_VirtualSetAttributes() does not work.

Workaround: Update the WinCE OS Image to at least the following version: - VFxx: V1.3beta4 - iMX6: V1.0

Description: SetPwm() Function is missing in the .NET wrapper file TdxAllLibraries.cs.

Workaround: The source file TdxAllLibraries.cs is part of the library package. Therefore usesrs can add this function themselves.

Description: Support PWM functionality

Description: SODIMM 59 and 67 are wrongly mapped to GPIO 48 and 49 respectively. Correct is GPIO 41 and 1 respectively. These two pins can be used as PWM signals.

Description: The documentation states that passing NULL as paramName2 parameter when calling Gpio_GetConfigString will return a string containing all the parameters. This is currently not happening and the function crashes if the parameter is NULL.

Description: I2C_Read and I2C_Write on i.MX6 returned -1 for an error or 0 in case of success, this has been fixed and now they return the number of bytes read/written as documented.

Description: When calling Gpio_Normalize() or VybGpio_Normalize() from a .NET application, an exception is thrown.

Workaround: Use the .NET wrapper of the library package V1.6 or later.

Description: When an application configures the "RegAddrSize" to 0 and tries to read data from I2C the libraries incorrectly generate a write request instead.

Workaround: For devices that can ignore a write request setting address size to 1 and doing a read can work.

Description: Adc_Init() generates an exception when run on a VFxx module under WEC2013. The same code is working well under CE6 and WEC7.

Workaround: Ask Toradex support for a preliminary version of the libraries including a fix for this issue.

Description: GpioLib: Gpio_Open() Fails, if a Registry Path is given, But no IO Entries are Present.

Workaround: Add at least one IO Gpio configuration to the registry.

Description: Spi_Init() generates an exception when run on a VFxx module under WEC2013. The same code is working well under CE6 and WEC7.

Workaround: Ask Toradex support for a preliminary version of the libraries including a fix for this issue.

Description: Implement support for the i.MX6

Description: Extend MapMem library to support the i.MX6

Description: The API for I2c_Read() and I2c_Write() has slightly changed: The type for the data buffer is now void* (it used to be DWORD*). No change is required for the user application.

Description: The API supports only "ioCs" as parameter and this prevents configuration of different chipselects.

Workaround: No workaround is available

Description: A parameter (HANDLE hGpio) was added to the functions Gpio_NormalizeIo() and VybGpio_NormalizeIo(). The source code in the user application needs to be adjusted for this change!

Workaround: none

Description: The Driver Name used inside the library was changed from "I2C0...I2C3" to "I2C1...I2C4". In the Vybrid OS Images V1.1betaX and older, an i2c driver for the default pins is loaded as "I2C0", which is used by the RtcSync Tool. The library now uses "I2C1" to access the default pins. This leads to potential collisions between RtcSync (using "I2C0") and a user application (using "I2C1").

Workaround: Will be fixed in OS Image V1.1 (not yet in V1.1beta2)

Description: Support SPI word widths of 4..16 bits on Colibri VF50 and Colibri VF61. Currently only 8 and 16 bits are supported.

Description: Implement I2C library for Colibri VF50 / VF61

Description: Create a .NET wrapper class to access the Toradex libraries. The current implementation is a preliminary, untested version.

Description: On Colibri VFxx modules V1.0x, SODIMM pin 102 was mapped to GPIO 93. On Colibri VFxx modules V1.1x and later, pin 102 is mapped to GPIO 5. The library requires an update to properly access pin 102 on new modules. The fix requires a Windows CE image V1.1beta2 or newer.

Workaround: Use the GPIO number 5 instead of the SODIMM number 102 to access the pin.

Description: Implement ADC library for Colibri VF50 / VF61

Description: The SPI library does not always configure the pin direction correctly.

Workaround: Configure the pin direction using the Gpio Lib. This issue will be fixed in Library Package V1.1

Description: Initial implementation of the MapMem library.

Description: Initial implementation of the Coproc library.

Description: Initial implementation of the Interrup library.

Description: Initial implementation of the PWM library for Colibri VF50 and Colibri VF61.

Description: Initial implementation of the MapMem library.

Description: When using SPI2, the library uses the SPI5 chip select.

Description: Receive Buffer Overflows can occur, especially if there are short messages with short idle time on the bus.

Workaround: Configure the library for Single Thread usage. This does not completely remove the problem, but it will minimize it by optimizing the library performance.

Description: xxx_GetConfigInt() may return gpios/pins in a different format than they were configured by calling xxx_SetConfigInt(). This needs to be considered when doing a comparison.

Workaround: To compare two Gpios, make sure that both are in GPIO format. You can achieve this by calling Gpio_NormalizeIo().

Description: Provide functions to store a short string for each GPIO identifiying the owner library/driver/application. The owner could be read back and for example be shown in the GpioConfig tool.

Description: VybSpi_ReadWrite() hangs if transmit buffer values are out-of-range.

Workaround: Make sure that each value in the transmit buffer is not larger than what the SPI word width can represent.

Description: Spi_Read() fails on Vybrid

Workaround: Use Spi_ReadWrite() instead

Description: When a Colibri T20 is updated in one step (through a .cfg file), and the .cfg file does not contain a splash screen, it is later not possible to save the registry.

Workaround: Include the previous splash screen in the package of update source files.

Description: RtcSync and othe i2c applications are blocked between calls of I2c_Init() and I2c_Deinit().

Description: When calling i2c_Read on a VFxx module, the device's slave address is always sent to the bus in "write" mode, even if there's no register address to transmit. This reduces performance unnecessarily, and even might be invalid for some i2c devices.

Description: Support SPI Slave Mode

Description: Support DMA mode for SPI on Apalis iMX6 and Colibri iMX6

Description: We don't plan to add special support for this.

Workaround: It's possible to map the controller using the MapMemLib and then directly access the registers.

Description: When doing SPI transfers using multiple chip selects, the byte order of the data can get mixed up.

Description: Add Thread-Safety to the GpioLib for iMX6 and iMX7

Description: Sys_GetConfigString("BuildDate") may return an outdated Build Date

Workaround: Check the file date of \Windows\initdb.ini
