Hi all,We design the custom board use ST32MP157 base on the design of STM32MP157-DK2 kit. We use the SD card for booting. The image and device tree is custom base on example of STM32MP157-DK2 kit. The board has a issue when booting via SD card. This ...
Hello, For some time I testing STM32MP135f with 1GHz CPU clocking. I was able to generate optee OpenStLinux but I see a lack of CPU efficiency. I'm curious what is the difference in efficiency between trust and optee. If I use the trusted option the ...
We are trying to bringup the Wi-Fi module connected over the sdmmc3 line with the STM32MP157F based custom board. But it seems, when enabling the sdmmc3 lines on the kernel and u-boot dts files, the kernel boot fails on "Waiting for Keymaster device"...
Hi all,I own an STM32MP157-DK1. I am trying to setup the TFT display ILI9341 on this discovery kit. I am familiar with Bitbake and Yocto. Are there any minimal images available that I can bake and dump on my discovery kit (SD card) to test my display...
Hi!I've been running an embedded linux (built with Buildroot) on a STM32MP157F-DK2. I need to use both USART3 and UART7 ports to interact with other devices.I've used it flawlessly with only USART3 enabled in linux's device tree for months. Recently,...
Hello,Searched around but couldn't find a similar issue.Please point me to one if one exist. I have a custom board with the stm32mp157c mounted. Board works fine, trying to communication between the m4 and a7 processor using the rpmsg devices. I have...
Hello!I make my M4 chip communicate with the A7 with openAMP from the example code.I send the data from M4 and currently A7 doesn't do anything.code is like belowchar buffer[512];//in the 1ms interruptif(currentPosition < 512){currentPosition = sprin...
Hi there, I am working on a custom board based on OSD32MP157F. The pinout is very similar to the stm32mp157f-dk2 with the main difference that the Murata LBEE5kL1BX-883 is connected to sdmmc3 instead of sdmmc2 and that there is no ethernet peripheral...
Hi,I would like to know STM32MP157F supports Windows 10 IoT Enterprise 2021 LTSC Operating System?
Hi,can some share dts configuration which allows you to bring up the PWM, timer etc?I do something like pwm_regulator { compatible = "pwm-regulator"; pwms = <&{/soc/timer@40002000/pwm} 3 500000 0>; regulator-min-microvolt = <1016000>; regula...
