Hi,A few weeks ago, I created a STM32CubeIDE project for STM32MP157F-DK2 where wrote my CM4 firmware. Everything went well. However, today I decided to make little changes in the code and now there are strange errors when building. IT IS NOT POSSIBLE...
Hi everyone,I'm using STM32MP157F MPU and I'd like to set the "autosuspend" parameter. It's allocated in /sys/module/usbcore/parameters/autosuspend and its default value is 2. When I modify its value to 0 and press the reset button, it becomes 2 aga...
When I don't use the .flags, i see the mode created, but my display doesn't work. I changed the ltdc register (GCR) manually to set DE and it works. When i add the .flags, no mode is created (i checked with modetest -M stm). Since i understood that t...

I am running Eclipse IDE for C/C++ Version 2021-06. I am using multiple stm32mp157x-DK2, When they are running kernel 5.4.x I have no problems connecting to them form Eclipse IDE via ssh, if I update them to 5.10.10, suddenly I get "Algorithm negoti...
Hello,we want to bring up our own board with STM32MP and ethernet phy LAN8720 (10/100 Mbps).Seems that kernel is recognizing ethernet phy on boot up and configure it with 100 Mbps Full Duplex.[ 2.907461] stm32-dwmac 5800a000.ethernet: IRQ eth_lpi ...
If I want to fully erase eval board STM32MP15F and then re-populate it back to its original out-of-the-box state. Is it enough to upload the flash layout from:en.FLASH-stm32mp1-openstlinux-5.10-dunfell-mp1-21-03-31.tar_v3.0\stm32mp1-openstlinux-5.10...
I am trying to have firmware_m4_X running on M4 core, and fimware_A7_Linux, runnin on Linux and them intercommunicating via RPMSx. If I upload them separately they work fine but after board reboot I want these two images to be started automatically. ...
We are generated a code from the Cube MX and written the application its working fine in debug mode through JTAG. But we want to put it into the Sd card . For this what is the procedure and how to enable the cortex M4 controller form A7.
Hello everyone,I received my STM32MP157C-DK2 device and I built a Buildroot-image and flashed it successfully.I am new to STM32 and to the IoT field so perhaps you can orient me and tell me which Programs I need to do so. I want to write a "hello_wor...
