HI,I'm not able to get the FDCAN filter working on a STM32MP157C-DT2. I'm able to receive valid ID' with no problem, however, invalid ID's are getting through.Would someone be kind enough to take a quick look at my setup to make sure I did not miss ...
I was working on the STM32MP157A-DK1 board which has Cortex-A7 + Cortex-M4 processors. I wanted to configure the watchpoints present specifically on the Cortex-A7 processor via C code. The Cortex-A7 technical reference manual indicates the use of MRC...
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...
