I used the latest official version（2021-03-31） to configure the stm32mp157c-dk2 of the optee version, and used the official tutorial to generate fip.bin and burn it to the corresponding partition, but it seems that the image is not checked,in other w...
Can I use STUSB1602 with STM32MP1?The STM32MP157C-DK2 has an STUSB1600, but it is not a PD controller, so I am reviewing the STUSB1602.STUSB1602 seems to support only STM32F0, STM32F4, STM32G, and STM32L.I'm curious to see if it is possible to port a...
Hi, I have tried to build the Distribution Package following this guide: https://wiki.st.com/stm32mpu/index.php/STM32MP1_Distribution_Package#Building_the_OpenSTLinux_distributionMy goal is to run a build that is as small as possible. Therefore I cho...
I'm working with the STM32MP157C-DK2 dev board and I've noticed that sometimes when powering up the board there is a 20-30 second delay where I don't even see the boot up messages. It's doesn't appear to be U-boot related either. Has anyone else not...
Hi, we are currently bring up our custom STM32MP157 Board. We get in any constellation a "DDR addr bus test: can't access memory @ 0xc000004"We think that our crystal is correctly running at 24 Mhz because we connecting over USB to the Board. Also th...
Openssl fails to convert the certificate from der to pem. Is this expected? I wrote a c program in OpenSSL to extract the public key, which seems to work, but I need to verify its correctness. Is there another tool like openssl that I can verify the ...

Hi:Dear friends, there is a very strange problem here. I use timer 1(STM32MP157AAC) to output PWM wave. In engineering mode, the output of PWM wave is normal, but when it comes to mass production mode, the waveform is interrupted. Here are my configu...
Hello,iam trying to implement more or less the same example as with the virtualUARTs with multiple Endpoints just with the rpmsg_char driver and plain endpoints without virtualUART on M4 side. Iam struggling to get multiple Endpoints to work. One is ...
