Hi, I have compiled the kernel source files and prepared the install artifacts as described in README.HOW_TO.txt, but when I am copying the modules into my STM32MP157C-DK2 board, it gets out of space. Moreover in the board I only have the modules rel...
I have custom board based on STM32MP157AAC3T CPU. I'm building image using yocto and board boots fine. Compared to devkit I'm using other panel .I've added driver + dts changes but I figured out that DSI drm driver is not probed. I checked dts on run...
Hi everyone, @Kevin HUBER I am using stm32mp157f-dk2 with ecosystem 3.1, with weston support.I connected the HDMI display to the development kit, reset the device, but nothing displayed.After checking, modetest show that the HDMI are properly conn...
Our board is similar to STM32MP157C-DK2 Disco board - All the Developer packages has been installed, the board is not booting whereas required power supply is provided, All the Test Points and passive components on the Board shows their desired Volta...
Not sure if this is the best forum for this question but I am using the USB OTG port in device mode as ethernet gadget. It works fine if plugged in from boot, or first plug in anytime after. But if unplugged and plugged in again it will not come back...
Hi,In this page, 3.5 (at the end) it is recommended that only a couple of layers are needed to get a non-distro version running.PC $> source layers/openembedded-core/oe-init-build-env PC $> bitbake-layers add-layer ../layers/meta-openembedded/meta-oe...
I'm trying to set up communication between the codec and the cm4 using the stm32mp157f-dk2 dev board. Debugging in engineering mode.I've set up the gpio, i2c1 and sai2 ports for the CM4 using cubemx, but the code fails when trying to send the require...
Hi supporter, I have two boards, one is my custom board and another is dk2. Those boards are not support high speed of mmc1. The mmc2 is into high speed and has 50Mhz clock.Below is some info about mmc1 and mmc2 on dk2 board.root@stm32mp1:~# cat /sys...
Hi all,I have been working with STM32MP157 chipset.I am currently trying to flash the OpenSTLinux to the SDCard using STM32CubeProgrammer inside VMWare.However, it failed in the middle of flashing.Can anyone tell me what I should do?Thank you
I am describing my approach as below:What we did:1) We are using the STM32MP157F-EV1 board (No other board is connected for this exercise, lines are open!)2) We are using OpenSTLinux(kernel:5.4) and we are using the firmware which was suggested under...
