Hello,
Thank you for reaching out with your concerns. Let’s address each of your issues with Torizon OS 7.
Issue 1: Cortex-M4 Program Prevents System Booting
The boot issue with the Cortex-M4 program might be due to changes in Torizon OS 7. Here are some steps to consider:
-
Compatibility Check: Verify that your M4 firmware is compatible with Torizon OS 7. Changes in the bootloader or kernel might affect M4 initialization.
-
Configuration Review: Double-check your U-Boot configuration, ensuring memory regions and boot parameters are correctly set for the new OS version.
-
Logs and Debugging: Try to capture any boot logs or error messages when the M4 program is loaded. These logs can provide insights into the reboot issue.
-
Example Programs: Since the Hello World example also fails, check for any updates or patches in the MCUXpresso SDK that might address compatibility with Torizon OS 7.
Issue 2: SPI Device Missing Under /sys/bus/spi/devices
For the missing SPI device, consider the following:
-
Device Tree Overlay: Ensure your device tree overlay is correctly applied. There might be changes in the overlay format or requirements in Torizon OS 7.
-
Kernel Changes: Review any changes in the kernel configuration or SPI driver support that might affect SPI device registration.
-
SPI Configuration: Confirm that the SPI bus and devices are correctly configured in the device tree, with the status set to “okay.”
-
Testing with Containers: If using containers, ensure the SPI device is accessible within the container. You may need to adjust permissions or use the
--deviceflag to expose the SPI device.
I hope these suggestions help you resolve the issues with your Cortex-M4 and SPI device on Torizon OS 7. If you have further questions, feel free to ask.
Best regards,
Toradex AI Assistant
