Hello everyone,I’m currently developing a custom board based on STM32MP151A, and I’ve successfully built my Open ST Linux (Yocto Scarthgap / v6.6) image using my own Device Tree generated from STM32CubeMX and further customized for our hardware.The ...
Hi ST Community,I’m using the STM32MP257F-DK board and successfully followed this guide: Modify, rebuild and reload the firmware Everything worked fine during the initial setup and firmware modification. Now I’m trying to flash a new image to the SD ...
Hello,we have product based on a STM32MP157 running Linux. The distribution is based on Yocto kirkstone and we are using a 6.1.82 Kernel. For the MP1s' GPU we use the open source entaviv driver that ships with this kernel. The device has a graphical ...
Honey, I purchased an STM32MP257-DK development board. I inserted a 16GB SD card, powered it with a 5V power supply, and connected the USB interface to the computer's USB port. After powering on, the COM indicator flashes red and yellow, and it canno...
Hello ST Community, We are developing a product based on STM32MP151 which has 2 (WKUP) GPIOs connected to wake our battery-powered product from sleep or shutdown. Can somebody please let us know how we can detect which GPIO triggered the wakeup in li...
Hello ST Community,I am currently working on a custom board based on STM32MP257FAI3, derived from the STM32MP257F-EV1 evaluation board.We initially built our own custom image and successfully enabled several peripherals (SPI, USART, Timers, ADCs, an...
Hi,I'm seeking information on where to purchase alternative LCD touchscreen sizes that compatible with the STM32MP257F-EV1 evaluation board, beside the standard 7-inch touchscreen LCD (P/N: B-LVDS7-WSVGA). It appears that ST’s touchscreen uses a diff...
As we are developing the camera streaming board for one of our client, I have the following queries:Both part numbers, STM32MP135DAG7 and STM32MP135FAG7 come in the TFBGA289 (9×9) package. Are the pinouts identical for both devices? can we interchang...
Hello everyone,I’m having trouble creating a custom image for OSD32MP157C-512-IAA and OSD32MP157F-512-BAA.When I try building the image for the 157C version using the Octavo tutorial [https://octavosystems.com/app_notes/stm32mp1-cubemx-tutorial-for-o...
Hello ST Community,I'm using the STM32MP257F-DK MPU board and wanted to enable the USART6 interface. We can access it from the 40-Pin GPIO expansion header of the board.For this, I have enabled the 'status' node settings of the usart6 from the device...
