Ask questions and find answers on STM32 microprocessors, including hardware, power, DRAM, flashing, interfacing, device tree, and peripherals.
Following the instructions here: https://wiki.st.com/stm32mpu/index.php/How_to_create_your_own_machineAnd then making a trivial devicetree modification (enabling I2C5 output) fails to build on a fresh yocto install (via the "distribution package"). ...
I am using the STM32MP257F-DK board. By default, this board automatically boots when power is applied. If the wakeup button is held for about 15 seconds, the system powers off. A short press and release of the wakeup button generates an interrupt sig...
Hello, I was wanting to make my own camera board and I wanted to use the same camera that is on STM's Camera board MB1854 and I looked up that manufacturer part number (AS-BC538A3M6-63(1.02.A3265)) and nothing showed up, and when I looked up just AS...
Hi, ST Community!We are developing a device based on the STM32MP257DAK3 processor.The firmware is built using Yocto (Scarthgap release) with Linux kernel 6.6 from ST and the meta layers meta-st-openstlinux and meta-st-stm32mp.The device includes a US...
Hi,I'm looking for information on the MP131F pin assignments for USB type-C signals CC1 and CC2. I'm working on a custom board that uses a USB type-C for power only as is done on the MP157D-DK1 board. thanks and best regards
I generated the M33 code from CubeMX, and linked libmetal, OpenAmp and building fine.But when initializing the OpenAmp using MX_OPENAMP_Init(), it get stuck at rproc_virtio_wait_remote_ready(vdev);The resource table and its parameters are exactly sam...
I generated the code using STM32CubeIDE for CM33 with FreeRTOS.I have tested the delay using osDelay(), the intervals are not accurate.I tried 1 sec delay using osDelay(pdMS_TO_TICKS(1000)), but its less than 1 sec. But HAL_Delay() comes to be quit a...
We are currently developing a demo product using the STM32MP257F-DK board.We have flashed the firmware using the file .images\stm32mp25-disco\flashlayout_st-image-core\optee\FlashLayout_emmc_stm32mp257f-dk-optee.tsvHowever, we found that the USB DRD ...
I am trying to debug a simple application on the CM4 processor on a STM32MP157D-DK1 development board in engineering mode using Cube IDE Version: 1.18.1 The board is booted from the micro SD card and appears to be powered up and alive with various fl...
Hi,when I understand the schematics of the STM32MP257-DK-board correct, the MDIO and MDC signals of the Ethernet1 interface are connected to some pins, which do NOT provide the MDIO and MDC functionality by default (AE15 which is PA10_ETH3_RGMII_RXD1...
