Can't complete pre-launch phase in CubeIDE
Hello everyone! I am following the tutorial on st wiki on how to work with STM32MP257F-DK board. Everything was going pretty good, until the “Develop on Arm® Cortex®-M33” part. This is a really important part for me, because the main reason I chose this MPU is because of the additional low-power cortex M33 and M0 co-processors. The part where I am stuck is “Modify, rebuild and reload the firmware for A35-TD flavor”. I have successfully built the “*_sign.bin” file and populated the board with it by using the “Run_Configuration” button. However past 78% the process stops and shows an error that states:
“Error in final launch sequence:
Failed pre launch
Failed pre launch
Firmware remoteproc load failed, please:
1. make sure that /lib/firmware on your target has space
2. make sure that /lib/firmware has write access
> you can open a Console View for this..”
In the STM32MP2 system a log of these messages are displayed:
“
[ 2321.306087] remoteproc remoteproc0: powering up m0
[ 2321.307801] remoteproc remoteproc0: Image is corrupted (bad magic)
[ 2321.311511] remoteproc remoteproc0: Boot failed: -22
“
I tried re-flashing the sd card with the correct .tsv file “FlashLayout_sdcard_stm32mp257f-dk-ca35tdcid-ostl-m33-examples-optee.tsv”, re-added the CubeIDE project and even re-did the “Run_Configuration”. I also saw that the “*_sign.bin” file is added to the /usr/local/projects/…/lib/firmware directory instead of the /lib/firmware directory, however after adding the “_sing.bin” file in the latter directory myself, nothing changed. I am lost on what to do next, hence why I am asking for help. Any advice is appreciated, thanks!
