Hi all,I was wondering whether we can achieve a PWM frequence of 1-3Hz with the existing timer which we have. I am targeting to generate a PWM signal within the same frequency range but using A7 as primary.How can we achieve that ?? I do have some id...
Hello,I am having a hard time setting the DDR clock at pll2 for an stm32mp157.The clock has been configured to 528MHz using CubeMX. I checked cfg for pll2 in the DeviceTree against the Datasheet / Referance Manual and all settings seem correct.Yet /s...
Hi,We are using stm32mp157a processor in my custom board.I need to select SPI2_NSS for PB9 But when i configure PB9 as SPI2_NSS it is not configured as SPI2_NSS.We are unable to enable Hardware NSS signal Option in Stm32 cube MX but it is mentioned i...
On the host computer, i try to connect the terminal to the STM32MP157F-EV1 board using ssh with Ethernet cable but I can't access I use STM32MP157F-EV1 board. I set manually the IP adress of board with Board $> ifconfig eth0 uuu.***.yyy.zzzthen I try...
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...
