Issue in loading Freertos Hello World file on Toradex Board. Getting Memeory error

[Abhishek05]

I am trying to boot FreeRTOS Hello world elf on the Toradex Board. But Getting some memory issue.
I first the below steps for remoteproc1 where the state is running but when trying with Hello world elf is not working
Flashing SD image .
Using uuu and the files imx-boot-variant-alt-imx95-19x19-verdin-sd.bin-flash_alt , imx-image-full-imx95-19x19-verdin.wic flash it to SD memory, these file are included in pre-built images.

E.g. on windows terminal:

uuu.exe -b sd_all .\imx-boot-variant-alt-imx95-19x19-verdin-sd.bin-flash_alt .\imx-image-full-imx95-19x19-verdin.wic

**Modifying uboot environment.**
iMX 95 Verdin

Stop in uboot

Add to mmcargs `pd_ignore_unused clk_ignore_unused` and boot. E.g.:
u-boot=> setenv mmcargs "setenv bootargs ${cpuidle} ${jh_clk} ${mcore_args} console=${console} root=${mmcroot} pd_ignore_unused clk_ignore_unused"
u-boot=> saveenv
Saving Environment to MMC... Writing to MMC(1)... OK
u-boot=> boot
After that, remote-proc can be used normally, I also share a log example

root@imx95-19x19-verdin:~# cat /sys/devices/platform/imx95-cm7/remoteproc/remoteproc1/state
running

I am attaching the error document.

Hello,

To address the memory error you’re encountering when loading the FreeRTOS Hello World ELF file on your Toradex board, here are some steps you can follow:

1. Verify ELF File Compatibility: Ensure that the ELF file is compatible with your specific Toradex module. It should be built using the correct toolchain and settings tailored for your hardware.

2. Check Memory Configuration: Memory errors often arise from incorrect memory allocation. Verify that the memory regions defined in your FreeRTOS project align with those available on your Toradex board. Pay special attention to the linker script used during the build process.

3. Review U-Boot Environment: Double-check the modifications made to the U-Boot environment. Ensure that the boot arguments, such as pd_ignore_unused and clk_ignore_unused, are correctly applied and do not conflict with the memory usage of your ELF file.

4. Remoteproc Configuration: Since you successfully used remoteproc with another ELF file, compare the configurations. Ensure that the Hello World ELF file is set up similarly, focusing on the firmware path and any specific settings required for your application.

5. Enable Debugging: If the issue persists, consider enabling debugging options in FreeRTOS to obtain more detailed error messages. This can help identify the exact cause of the memory error.

By following these steps, you should be able to identify and resolve the memory issue with your FreeRTOS Hello World ELF file. If further issues arise, reviewing the build and configuration process for any discrepancies might be helpful.

Best regards,
Toradex AI Assistant.
