I followed the guide from the following ST's video: https://www.youtube.com/watch?v=PsiFDHH87vo&t=407s In the guide, the A7 core is initiating the communication. I have been playing with the code to make M4 the one to initiate the communication, but ...
HiI try to implement a virtual UART communication between the A7 and the M4 on a STM32MP157 device based on OpenAMP. I used the OpenAMP_TTY_echo example from the cube firmware package and adapted it to my own board. The virtual UART is working. But t...
Hi.... there Hope you all are doing well From past few days, I'm playing with STM32MP1I need to integrate the Quectel EG25G module with the image having ppp functionality To do so, i have enable ppp support at Make-menuconfig and build the image Now...
Hi everyone,I'm new to using STM32MP1, in particular I bought a STM32MP157A-DK1 and I wanted to know if it was feasible to load Linux with the classic GUI, open a TCP-IP server and run some python code that I had already developed.Thank you all
Same situation as before - using a STM32MP157C based design + KSZ9021GN PHY but now actually wired for MII mode. Previous board was wired for GMII mode, even verified by Microchip/Micrel, not realizing the MPU did not support that mode (should have c...
I am debugging a STM32MP1 boot but the bootrom does not manage to boot the FSBL from the SDMMC interface.I extracted the traces and ran the bootrom trace analyzer script. However, some of the error messages contain error codes for which I could not f...
Hi,I want to perform the SSP process as detailed at:https://www.st.com/resource/en/application_note/an5510-overview-of-the-secure-secret-provisioning-ssp-on-stm32mp1-series-stmicroelectronics.pdf(I also went over the STM32_prog documents)I am now try...
Our board is similar to STM32MP157C-DK2 Disco board - All the Developer packages has been installed, At the initial FSBL stage itself board is not booting whereas required power supply is provided, In which the Voltage (VDDCORE_1V2) value related to...
Hello. I've been trying to make the ADC work in my stm32mp157f-ev1 board. It is my understanding that I need BSP to make it work because when I disabled BSP in the ADC example code I noticed receiving the same result as my code. When I try to add the...
