Hi,We are using stm32mp157a processor in our custom board. In Stm32mp157a-Dk1 board i am able to run Cortex-M4 code in uboot using rproc commands Cortex-M4 is working fine. Where as in my custom board I followed the same sequence but Cortex-M4 is not...
Welcome, why for STM32MP157FAA1 at "STM32MP1 Series DDR memory routing guidelines examples" there is no terminating resistors?
we are developing the application by using STM32MP1 processor in bare metal.we are able to wake up Cortex A7-1 from Cortex A7-0 both are working fine. Now we tried to wake up Cortex M4 from Cortex A7-0,But we are unable to wakeup Cortex M4 from Cor...
Using the KMS/DRM driver, how can I change the emulated framebuffer format? I'm using simple-panel and the framebuffer has always only 16-bit color even though the driver explicit sets the format for 24-bit colors (.bus_format = MEDIA_BUS_FMT_RGB888_...
When using DCMI camera capture and at the same time play or record audio, there is bad interference in the camera picture. I'm using Linux and ALSA libraries in a platform based on STM32MP157C. Maybe some DMA problem ? The audio is using SAI as with ...
hi,i would like to be able to control the pmic from user space. everything that i have read in the stm documentation indicates that it is not possible to do this. the sysfs interface is read only. i would like to be able to access the consumer dri...
Hello,In the wiki I have found these lines:5.3 Non-volatile counters↑Each certificate embeds a non-volatile counter value that is checked to control anti-rollback mechanism.There are two non-volatile counters: - Trusted non-volatile counter - Non tru...
