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
Hi All, I'm trying to boot a custom board using the Starter Package through the STM32CubeProgrammer. I'am flashing the SD Card on the board through the UART interface as USB interface(CN7/USB_OTG) is not provided for the board. During this process I'...
Hello all,I'm working on a custom board based on a stm32mp157c & stpmic1 (connected on I2C4). We are using secure boot and have configured the I2C4 to work in secured mode. To control the stpmic1 from the unsecure / normal world, we use the scmi-reg...
Hi, We would like to drive pin PWR_ON to low for low power mode.First, on MCU, we use HAL library: HAL_PWR_EnterSTANDBYMode(), load to M4 and run it first, so M4 now enter standby mode.Second, on MPU, we set TZEN=0 so non-secure, allow us to modify P...
