I have a custom MCUboot boot loader working. Now I'm trying to build an application to be updated by MCUboot. I've added the following to prj.conf:
CONFIG_BOOTLOADER_MCUBOOT=y
CONFIG_MCUBOOT_SIGNATURE_KEY_FILE="/<my full path>/root-rsa-2048.pem"
When I try to build the application, it compiles, but then there is a signing error:
Error: Invalid value for "-H" / "--header-size": Minimum value for -H/--header-size is 32
Any idea why this would be happening?
If I try to sign manually with:
$ west --verbose sign -t imgtool -- --key /<my full path>/root-rsa-2048.pem -H 32
Then I get a different error:
west --verbose sign -t imgtool -- --key ~/sandbox/itamar/workspace/itamar/foundation/samples/bootloader/app_bootloader/root-rsa-2048.pem -H 32
Should NCS be padding with zeros for the header? And how much padding does NCS use? Where is this configured?
Full output of west build:
$ west build --pristine

WARNING: This looks like a fresh build and BOARD is unknown; so it probably won't work. To fix, use --board=<your-board>.
