I'm trying to rebuild the kernel as described on the wiki page. When I run make, the wiki shows unexplained choices that eventually result in an error. Is there a possible problem?(unexpected) following choices appearBest Regards
We are using Stm32mp157A .We Want to generate Interupts in Core0.For this we are using System timer Generator .We enable STGN and loaded Frequency value(STGN_CNTFID0),STGENC_CNTCV is increamenting . But we are not getting interrupts.We configure GIC ...
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...
