I am adding the STPMIC1 on our custom board.While configuring device tree, when we are using scmi, how should device tree configuration look like? Should we still need to add i2c4 node? Or just adding scmi_regu entry will be enough?Regards,S
I am attempting to implement a second ethernet interface on STM32MP157F-DK2 by using the Arduino Ethernet Shield, which is based on the Wiznet W5500 chip. The implementation aims to use SPI assigned to A7 core to communicate with the shield, which wi...
Hello,We are currently working with the STM32MP157F-DK2 board and the on-board SDRAM (DDR3L). The memory map says that region (0xC000000-0xDFFFFFFF) is for the DDR system, however when we try to write to some of the memory locations inside this range...
Hi, on SPI, does anyone know why every 8 bytes then it has a big gap?We tried:1MH, no gap,2MH, gap occurs,4MHz gap bigger,8MH gap bigger than 4MHzSeem higher frequency, bigger gap We don't use DMA
Hello everyone,we have developed a custom board based on stm32mp157 chip. We also forked the tf-a and u-boot from meta-st layer. If we flash an sd card using the flash layout, image works. But my goal is to copy the files from linux host machine, whi...
Hi,I am working on cross-compiling one of the third party device driver for running it on STM32MP135F based customize board.Currently in my cross-compilation following errors are triggered with respect to GCC cross-compiler setup using the SDK for Op...
I completed upto modify a build in linux on board following this link Now i am getting issuses like display doesnt turned on and .Not able to connect with board via ip address. After connect with ttyacm0 its showing like the board has struct in st...
I have been observing a issue in some cards based on STM32MP135f processor that tee-supplicant service getting failed after I program my board. I also observed that modules are not getting loaded. But when I reprogram it then all things become okay. ...
STM32MP257F-EV1 availability date is 2024. Do you have a more precise date for this evaluation card?Thank you in advance for your responses.Best regards
Processor stm32mp157f, our board design similar to dk2.In my STM32CubeMX generated device tree (dunfell) I have added the following:/* USER CODE BEGIN root */soc {vrefbuf@50025000 {status = "disabled";};};/* USER CODE END root */I have my vref pin co...
