I am working with the STM32MP1-DK2 development board and am trying to use RAUC to do image updates. I am using an SD card with two bootfs and rootfs partitions with one pair being active at a time. Currently I'm in the uboot integration stage where I...

I am working with the STM32MP157 creating an SD card image using OpenSTLinux. I would like to use RAUC to perform updates but to do so I need to create a second rootfs partition. One active partition and the other for updates. I couldn't find in the ...

I am using the STM32MP15-DK2 dev board and with a modified device tree to enable some peripherals. I would like to use /dev/watchdog to reset if ever my application hangs. But whenever I try to open the device I get Error opening watchdog device: Dev...

I'm working with the STM32MP157C-DK2 dev board and I've noticed that sometimes when powering up the board there is a 20-30 second delay where I don't even see the boot up messages. It's doesn't appear to be U-boot related either. Has anyone else not...

I am configured both the FDCAN interfaces on the STM32MP1 discovery board with the settings below using STM32CubeMX. FDCAN1: PA11 (RX) PA12 (TX)FDCAN2: PB12 (RX) PB13 (TX)But I can't seem to get any data from either interface. I have a logic analyzer...

My final solution. In the end I changed the first boot partition to just have the boot.scr.uimg since it needs to be in the first partition after u-boot. Then created another rootfs and two bootfs with all the typical bootfs stuff ie. kernel, device ...

In the end I actually did not have to rewrite any of the u-boot variables. I removed the extlinux/extlinux.conf file from my bootfs and had the boot.scr.uimg script change the variables i needed.

I see now it's because boot.scr.uimg' U-Boot script is executed only if 'extlinux/extlinux.conf' is not found.https://wiki.st.com/stm32mpu/wiki/How_to_start_the_coprocessor_from_the_bootloaderA follow up question though? Is there recipe I can extend ...

Hey Christophe,Thanks for the reply I can see the scan command and will replace the scan with hard coded values based on the active partition.I am now trying to get uboot to run the boot.scr.uimg script as recommended by rauc. I've created a recipe c...
