BSP Layers and Reference Images for Yocto Project Issue Tracker

 

The following table contains known issues, scheduled bug fixes, and feature improvements for the Toradex BSP Layers and Reference Images for Yocto Project.

The tickets are split into two major states:

  • Submitted (open): new features and bug fixes for BSP versions that have not yet been released. They may be scheduled for a specific release version; not planned; or in our backlog. All of them have one of the following states:
    • Known Issue: a bug or unexpected behavior that has been reported and is pending a fix. Once fixed, the status will transition to Fixed.
    • Feature Request: a new feature that may be added to a future release. Once released, the status will transition to New Feature.
  • Released (closed): new features and bug fixes for BSP versions that have already been released. All of them have one of the following states:
    • Fixed: a bug that has been fixed and released.
    • New Feature: something that didn't exist before and was added to a new release.


Any schedules are not guaranteed but reflect the current planning. The planning could be shifted due to priority changes.

Issues that are scheduled for a specific version will be integrated into the mentioned version of the BSP.

We will update this table continuously in order to always provide the latest state of our development plan. Please see also the Linux Support Strategy to learn more about the different releases.

Issue #StatusSubjectModuleSubsystemWinCE OSSeveritySubmitted for Mainline

6.6.0 (Release date: 2024-03-31)
Upcoming Embedded Linux BSP Q1 2024 Quarterly Release
ELB-5585Known IssueHDMI clock doesn't stop when HPD pin changes to "disconnected"Verdin iMX8M PlusHDMILowNo

Description: The native HDMI clock signal keeps running when a Hot Plug Detect disconnect event is received but the cable is still connected

ELB-5237Known IssueVerdin iMX8MP native HDMI only works when verdin-imx8mp_dsi-to-hdmi_overlay.dtbo overlay is enabledVerdin iMX8M PlusDSI, HDMILowNo

Description: It's not possible to use the native HDMI port with the overlays verdin-imx8mp_mezzanine_panel-cap-touch-10inch-lvds_overlay.dtbo and verdin-imx8mp_hdmi_overlay.dtbo as described in our documentation.

Workaround: Use the overlays imx8mp_mezzanine_panel-cap-touch-10inch-lvds_overlay.dtbo, verdin-imx8mp_hdmi_overlay.dtbo and verdin-imx8mp_dsi-to-hdmi_overlay.dtbo to get a working display.

6.2.0 (Release date: 2023-03-31)
Embedded Linux BSP Q1 2023 Quarterly Release. Learn more on https://www.toradex.com/news/bsp-layers-reference-images-yocto-project-6-2-0-quarterly
ELB-4728FixedMissing Video Modes On HDMI InterfaceVerdin iMX8M Mini, Verdin iMX8M PlusDSI, Graphics, HDMILowNo

Description: Some monitor might not work (no display signal) or use a mode different from the preferred one using the HDMI interface, this is because video modes are filtered out if the monitor expected pixel clock is "too" far from the clock that the SOC is able to produce.

6.1.0 (Release date: 2022-12-31)
Embedded Linux BSP Q4 2022 Quarterly Release. Learn more on https://www.toradex.com/news/bsp-layers-reference-images-yocto-project-6-1-0-quarterly
ELB-4731FixedDSI-to-HDMI Adapter Hotplug Detect (HPD) Not WorkingVerdin iMX8M Mini, Verdin iMX8M PlusDSI, HDMILowNo

Description: DSI-to-HDMI does not implement hot plug detect on event, a 10 seconds polling is used instead. Because of that timing could be incorrect when a different monitor is plugged in.

5.3.0 (Release date: 2021-07-08)
Embedded Linux BSP Q2 2021 Quarterly Release. Learn more on https://www.toradex.com/news/bsp-layers-reference-images-yocto-project-5-3-0-quarterly
ELB-4015New FeatureNative HDMI Only can Provide a Discret Set of PixelclocksVerdin iMX8M PlusHDMINo

Description: For native HDMI the pixelclock is provided by the a PLL in the HDMI PHY. The driver for the HDMI PHY accepts only modes with a pixelclock which matches a list of driver provided frequencies. This masks out EDID modes with one of these not compatible frequencies. Change the driver, so that it offers the closest frequency and change the bridge driver to accept also not exactly matching ones.

ELB-3361New FeatureFeature Set: Linux: HDMIVerdin iMX8M PlusHDMINo

Description: Add support for HDMI (both native as well as via DSI-to-HDMI display adapter) on Verdin iMX8M Plus V1.0B.

Not Planned
ELB-4796Known IssueBroken Display Output When Switching HDMI PortsVerdin iMX8M PlusGraphics, HDMILowNo

Description: When switching back and forward between the integrated HDMI port and the one from the DSI-HDMI adapter, the display output image can get corrupted with wrong zoom and positioning issues.

ELB-4333Known IssueRace Condition During Boot May Cause Different Order Of HDMI vs. I2S Audio DevicesVerdin iMX8M PlusAnalog Audio, Digital Audio, HDMILowNo

Description: A race condition during boot may cause a different order of native aka on-module HDMI vs. on-carrier I2S audio devices.

Workaround: Do not use the soundcard device index to identify the output (e.g. based on aplay -l output).
