Hi all,I am trying assign DMA to USART3 channel on STM32MP1.I assigned it appropriately in the CubeMX but it looks like it was not able to auto-generate any code regarding the DMA assignment to the USART3.The device-tree bindings look pretty confusi...
Hi all,Referring to previous discussion I had.I just want understand what are the PWM limits for STM32MP1.I can't seem to generate PWM signal below 100ms. Any inputs will be appreciated.My target frequency is 1KHz.https://community.st.com/s/question/...
Hi all,I have configured TIM1_CH3N as a pwm channel.I am trying to do some PWM functionality here.I am following current tutorial here. When i tried to provide a period of 10 sec it fails to take up the value. I get following error :root@stm32mp157a-...
Recompiling Linux kernel I have to rebuild the whole image because of kernel-modules, that are dependent on kernel version. After that I have to upload the whole image into STM development board via CubeMX Programmer which takes quiet a lot time. Ho...
Have been struggling to get SPI to work. I have been working in the engineering boot mode to try and trouble shoot my issues. I have configured PLL3 to run the MCU at 48MHz and the SPI peripheral kernel clk to run at 108MHz and selected the clock so...
Hi again, hope you are having a good day. We are trying to record audio with the integrated audio codec with a python script, but it starts with an abrupt peak every time like the image below.We have tried to configure the alsamixer and nothing chang...
I am using 2 virtual UARTs as described in STM32MP1Cube Applications/OpenAMP/OpenAMP_TTY_echo example and watchdog for M4 core.Problem occurs when I using select or poll syscall to read from the device. Kernel panic occurs with following on dmesg log...
Hello!I have an issue on a custom board with STM32MP153CAB and KSZ8081RNB.TF-A, FIP and kernel were built in Developer package. Linux distribution was built as startard configuration st-image-core in Distribution package.Clocks and device trees are c...
I'm using STM32MP157A-DK1 development board, in this we are using it for audio application,I'm porting stlinux in the board by yocto BSP.I wanted to know the codec(CS42l51) available on the board at what default clock it is operating and is it using ...
