Re: MCUboot - Signing image for slot 1 #mcuboot
toggle quoted messageShow quoted text
Thank you for your reply. Sorry for the late response, as I have been getting sporadic results, i.e. sometimes the image upgrade works and most of the time it doesn't.
I have been using the following commands to sign and flash the image:
rm -r build && west build -p auto -b nrf52840dk_nrf52840 samples/zephyr/hello-world/ -DCONFIG_BOOTLOADER_MCUBOOT=y -DDTC_OVERLAY_FILE="boards/nrf52840dk_nrf52840.overlay"
west sign -t imgtool -- --key ~/zephyrproject/bootloader/mcuboot/root-rsa-2048.pem --header-size 0x200 --align 8 --version 3.0.2+1 --slot-size 0x67000 --pad && west flash --skip-rebuild -- --hex-file build/zephyr/zephyr.signed.hex
where the overlay file contains:
zephyr,code-partition = &slot1_partition;
I used --pad for both slots. I've noticed that sometimes when I flash to slot 1, sometimes the primary image swap_type=0x2 (test) and sometimes it's 0x4 (revert).
I have confirmed that I am flashing my slot0 and slot1 images to the correct addresses (with padding).
I am not sure if the Version number plays a role in my error. Do you have any suggestions on the top of your mind as to why I am getting sporadic results with the firmware upgrades?
