Hello,I have a custom board based on STM32MP151-C with an eMMC on the following pins:SDMMC2_CK PE3 (AF09)SDMMC2_D0 PE6 (AF07)SDMMC2_CMD PG6 (AF10)I read that the ROM expects the the SDMMC2_D0 pin on PB14 so I need to change it by using values from...
Hello,We have an issue with QML multimedia to display camera stream. The result is not smooth while with Qt widgets it works fine. Gstreamer pipeline from command line works as well. The hardware is a STM32MP157C SoC which provides a Vivante GCnano a...
I would syncrhonize A7 and M4 on STM32MP151A using IPCC interrupt, how can I do it? Moreover, using FreeRTOS, I need to start some task before of MX_OPENAMP_Init, but I noticed if I move this function after the Kernel starting, it doesn't work. I do...
Hello ST Support team,I have MP23DB01HP digital MEMS MIC sensor which has PDM output. I was gone through "AN5027" application note. I want to connect this digital MIC with DK2 to find dB data from it.suggest me steps to connect and run mic on DK2 boa...
Hi: I encountered a strange problem when I tried to operate the gpioz pin with the gpioset command in user space and found that the level never changed. Can you give some suggestions to solve it.
