Hi all,We have a custom board based on stm32mp157f-dk2, with small changes. But we have an issue that the board will not wakeup after remoteproc0(m4) is turned off (cmd: echo stop > /sys/class/remoteproc/remoteproc0/state). When m4 firmware is runni...
Working on setting up SPI bus and get a connection to ESP32C6 WiFi/BT module. Trying to configure SPI5 clock in device tree for STM32MP151. Have used different sources (HSI, HSE, PLL4Q), but the enable count on the SPI5_k clock is always zero. I am s...
any tips on how to enable and debug pll4_r and fdcan_k clock?
Hi,i implemented our TF-A update by using both bootareas:1) checking EXTCSD for active bank2) flashing opposite bank3) after verification switching EXTCSD (mmc bootpart enable)not failsafe but at least atomic / verified.(btw, i'm missing the feature ...
Hi I used pip3 install python submodule.The submodule inclued xxx.c files.The install processing be use 'arm-ostl-linux-gnueabi-gcc' compiler tool, The processing be fail.I can't find gcc-arm-aarch32-arm-none-linux-gnueabi tool for The STM32MPU157-DK...
Hi,i'm implementing our field-update using the A/B mechanism for FIP image.Would like to use the Update Client described on the page as a template:https://wiki.st.com/stm32mpu/wiki/Secure_Firmware_Update#Update_ClientBut no idea where to find it. I d...
Hello everyone!I am trying to bring up a custom board based with a STM32MP151 (C Variant) with OPTEE, TF-A and U-BOOT.So far so good, but when running the FIT Image (Kernel + DTB) it fails finding the boot storage. It looks like the device-tree is no...
Hi,I have written a cpp program with two threads, one thread for uart serial communication and other thread to control the GPIOsi have compiled it, and i got a binaryButWhen i transfered it to the board i get the error ./fw_dali_controller: line 1: s...
Hi! I am using an STM32MP153 and am working on implementing the STOP mode functionality for my application. The MCU shall wake up on a falling edge on pin PI8. The pin PG15 has an interrupt attached to it for another functionality. Before going into ...
Hi,I use in my project STM32MP153, which is a model without a GPU. My application also doesn't need any graphical representation like Wayland, X11, etc. How can I update st-image-weston.bbappend to remove these unnecessary elements?ThanksMW
