Hardware: STM32MP157C-DK2, VL6180 breakout from SparkfunSoftware: CubeMX IDE (1.3.0), buildroot (following the guide from Bootlin here)I'm trying to use the M4 core to communicate with an I2C sensor. I successfully talked with the sensor on the Linux...
Hi,we are currently evaluate the STM32MP for a project and we want to ensure that we can handle all errataissues that concern our usage scenario.In Errata are the points: 2.6.1 to 2.6.4 that discribe DMAMUX issues. At this point my question is:Does L...
Hello guys.I am proceeding in the manner provided on the WIKI page(https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_Package).However, the following problems still occur in Step 6.[error codes]-----------------------------------------------...

Hi All,I'm coding last from 6 years for embedded system projects. I have good knowledge in bare metal programming. I want learn Linux and device driver implementation using Linux.Please suggest me a board, with which I can start my Linux learning jo...
Hi, I have an STM32MP157C-DK2 reference board and it is booting with yocto linux.From the bootlog I came to know that reset reason is checked in the Primary Bootloader by reading a register from the file tf-a-stm32mp/plat/st/stm32mp1/bl2_plat_setup.c...
To bootup STM32MP157 from SD card, the layout for SD is partition#1, u-boot-spl.stm32, first copy of first stage bootloader partition#2, u-boot-spl.stm32, second copy of first stage bootloader partition#3, u-boot.img, second stage bootloader partitio...
Hi,i try to use a ADM DMA with the board in object.I generate the code with CUBE MX and i add only the function HAL_ADC_Start_DMA(&hadc1, (uint32_t*)&buff, 1); before the while loop in the main.After i start the ADC, the hadc1.State remains in HAL_A...
Hello,I am working on a project that acquires ADC readings and saves them into a buffer in the M4 side of STM32mp157 chip on DK2 board, now I need to build a kernel module that copies the saved buffer from the SRAM to DDR on the A7 side when a certai...
