Hi everybody, I'm trying to configure the Wi-Fi module on my custom board (based on the STM32MP153, the Wi-Fi module already tested OK) in Access point mode, and I found the official guide to set hostapd tool to do that: https://wiki.st.com/stm32mpu/...
Hi,I'm attempting to test some Object Detection demo models from the X-LINUX-AI expansion package on the STM32MP157D-EV1 eval kit with a live camera video stream. However, I'm currently having what seems like a streaming problem with both the C++ or ...
Hello. We recently purchased a complete set of stm32mp157x-Ev. The documentation shows only the main connectors. Where can I find a complete schematic for both boards?
Hey All,So I know it's mentioned in the data sheet that the stm32mp1xx MPU's only support 16/32 bit DDR ram, and that it also mentions the limit of 1GByte total ram, but I just wanted to confirm this isn't possible and specifically why as I cannot f...
Hello, I am currently using bare-metal MP13 solution in CubeIDE. I want to integrate uart with DMA. After configuring DMA settings for uart4, a following fragment of DMA init code has been generated:NVIC is not available for Cortex-A, but still its f...
Hi, I am using STM32MP153 and DCMI interface, camera OV5640.we are using DT same as here: DCMI device tree configuration - stm32mpuFor 640x480 or higher, we always get dma error as below:For 320x240: Seems first capture has no problem, but start from...
We are currently experiencing a major issue with eMMC on our custom boards using STM32MP153CAC. Our boards are booting normally with 1 wire mode, but as soon as 8 wire/bit mode is enabled, it starts to bug out.Here is the description of the problem f...
We have set SDMMC1 pin muxing like below. How can we boot from emmc on SDMMC1 interface??? Where should I do partitioning for emmc??Kindly give solution- D14 PC8 SDMMC1_D0A16PC9 SDMMC1_D1B14PC10 SDMMC1_D2C14PC11 SDMMC1_D3A13PB14 SDMMC1_D4D9PB12 SDMM...
Hello,U-Boot has an stboard command that writes a board ID into OTP (word 59 on STM32MP15x lines, word 60 on 13x lines).TF-A displays this board ID if a device tree label "board_id" is present in the bsec node.Could you please explain the purpose of ...
