Hello,
When upgrading from Torizon OS 5.7 to 6.8, several factors could affect the functionality of the USB client RNDIS on your Colibri iMX8. Here are some steps and considerations to help troubleshoot and resolve the issue:
-
Kernel Modules and Configuration: Ensure that the necessary kernel modules for RNDIS are loaded. In Torizon OS 6.8, there might be changes in how these modules are managed. Check if the
g_ethermodule is loaded usinglsmodand load it manually if necessary withmodprobe g_ether. -
Device Tree Changes: Verify if there are any changes in the device tree that might affect USB configurations. Compare the device tree used in Torizon OS 5.7 with 6.8 to ensure that USB client settings are consistent.
-
Network Configuration: Check the network configuration scripts or services you used in Torizon OS 5.7. There might be differences in network management between the two OS versions. Ensure that any custom scripts or services are compatible with Torizon OS 6.8.
-
U-Boot and Bootloader: Since upgrading involves changes to the bootloader, ensure that the bootloader is correctly updated and configured. Incorrect bootloader settings can affect USB functionality.
-
Logs and Diagnostics: Check system logs (
dmesgandjournalctl) for any error messages related to USB or network interfaces. These logs can provide clues about what might be going wrong. -
Windows Driver: On the Windows side, ensure that the RNDIS driver is correctly installed and that there are no issues with the USB connection.
By systematically checking these areas, you should be able to identify and resolve the issue with the RNDIS functionality on Torizon OS 6.8. If the problem persists, consider testing with a minimal setup to isolate the issue further.
I hope this helps you get your setup working smoothly again.
