Hi @OlivierK ,I am using openstlinux ecosystem release v3.1.1 and trying to use secure boot feature with yocto and as per https://wiki.st.com/stm32mpu-ecosystem-v3/wiki/TF-A_overview we need to set "TRUSTED_BOARD_BOOT=1".We need use "TF_A_SIGN_ENABL...
On an STM32MP157C the IWDG is setup correctly, but when I trigger an endless loop in U-Boot or a panic in the Kernel, after the timeout the reset does not work. All I know is that the debugger shows a Vector catch. In OPTEE OS the reset works. Is thi...
hi st expertI am porting openstlinux for my robot board, I found that the system froze after uboot selected the extlinux file, and then rebooted after a while，the uart log :Do I have any debugging means to analyze where the current problem is? than...
I followed the instructions here with a STM32MP157F-DK2 board till before step 8, with a serial console to the board set up. However, instead of booting into "root" as described, from the console output my board enters "emergency mode", and the last ...
Hello We are implementing WWDG watchdog in our custom board to cortex-M4 core in cubeIDE tool. We initialise the following registers -> enable the clock to WWDG -> In control register enable the Watchdog enable bit and watchdog counter. -...
When I design the FPGA interface, I need the detail timing para. when M4 in memory map mod. Where can I get the docu? thank you
The board is set up as follows, and USB of ST-Link V2-1 is connected to Host PC. when using Linux host pc , /dev/ATM* devices not recognized.So I used a Windows PC, but it is not recognized either.Do I need to install a special driver to recognize ...
Hi ~I'm using my custom board with STM32MP157C MPU. I'm currently trying to adjust the LCD brightness using PWM.And I was able to implement it by referring to the link below.https://community.st.com/s/question/0D50X0000AvgWuGSQU/how-to-use-timers2-a...
