WEC iMX6 BSP Release

 

The following table contains known issues, scheduled bug fixes, and feature improvements for the iMX Windows CE BSPs and images.

Any schedules are not guaranteed, but reflect the current planning. The planning could be shifted due to priority changes.
Issues which are scheduled for a specific version will be integrated in the mentioned version of the BSP.

We will update this table continuously in order to always provide the latest state of our development plan.

Odd beta versions, as 1.0b1 or 1.3b3, are internal releases only for testing. They are omitted from the table.

WC-657New FeatureI2C does not keep different frequencies for different apps invoking the driverApalis iMX6, Colibri iMX6I2CWEC7, WEC2013

Description: When multiple applications access the I2C driver (directly or using libs) they can change bus frequency. This change is global and affects all the communication operations performed by the driver after the change. Since there is no way for apps to be aware of frequency changes and those cannot be performed in an atomic way together with transfers, we changed the driver to support different frequencies for each instance (each app that calls "open"). Applications using the libs can do multiple I2C_Init calls to use different transfer speed. Of course using different speeds for devices connected to the same bus is not the best thing to do from an HW point of view, but this solution can allow better performances for drivers requiring fast transactions or significant data transfers.

Workaround: Issue has been fixed in rev. 1.1B4. No changes are required for applications and libraries.
