hi,st engineer I am required to conduct Ethernet debugging on an stm32mp157a-st-discovery development board running the RT-THREAD operating system. Within the stm32mp157 Processor Reference Manual, I've encountered such option as follow:10/100M Gigab...
I am using STM32CubeMx to generate device tree:I got these in uboot device tree:&rcc {st,clksrc=<CLK_MPU_PLL1PCLK_AXI_PLL2PCLK_MCU_PLL3PCLK_PLL12_HSECLK_PLL3_HSECLK_PLL4_HSECLK_RTC_LSECLK_MCO1_HSICLK_MCO2_DISABLED>; st,clkdiv = <1 /*MPU*/0 /*AXI*/0 /...
Hi,Currently i am looking for an easy way:to change the device tree, to assign peripherals to the M4 Coprocessor for quasi real time applications. i do have a STM32MP157F-DK2 board for testing and also a board with Debian, which i purchased from a di...
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...
