Hello, I've got a board with an STM32 MP CPU and I have to reduce the size of the final image to leave enough space on the NAND memory for a dual rootfs setup. The idea is to remove the alsa layer because I don't need the audio part. I tried to add t...
Hello,I have 7 ADC channel , and its configue as interrupt. But the interrupt each is get generated for different condition how I can check the which ADC channel interrupt is get generated which I have to use the function for distinguish the ADC chan...

Hi everyone,I am thinking about using STM32MP1 for a smart wearable device, like a smart watch to run some machine learning algorithm. is it possible? is the battery able to support MPU?Does anyone know any product already used STM32MP1? it would be ...
Hello,I tried to enable spread spectrum for PLL1 by adding a csg line to the TF-A DeviceTree:pll1:st,pll@0 { compatible = "st,stm32mp1-pll"; reg = <0>; cfg = < 1 49 0 1 1 PQR(1,0,0) >; csg = < 60 600 SSCG_MODE_CENTER_SPREAD >; };I tried several d...
Hi,on a custom board with a STM32MP153AABxx and a W63AH6NBV 1Gbit LPDDR3 memory I am failing to initialise the DDR properly. I made the required changes to the upstream u-boot device tree files, added support for UART8 debug console and some minor th...
HiWe are using stm32mp157a processor in our custom board.we have an 3 port Ethernet switch(KSZ9893RNXIA) with spi interface to processor.We enable Ethernet switch using spi.Read and write to switch is working properly.But we when we connect Ethernet...
Hi,During the actual production of our stm32mp157c products we do intend to use the HSM flow.But for now I am simply trying to test the SSP flow with some debug (development) keys and without access to an HSM.I went over:https://www.st.com/resource/e...
Hi STM-Team,We have the custom board based on the STM32MP157C-Eval board.In that, we are not able to access the eMMC from u-boot command prompt. Currently, we are booting from SD card and able to access it from u-boot command prompt.We are able to se...
