west sign fails to find header size or padding

[paulgavrikov]

I am using west 0.7.1, Zephyr 2.2.0 and SDK 0.11.2 and would like to sign an image for mcuboot.
The following command works on my desktop, but fails on our jenkins CI: west sign -t imgtool -- --key <key>.pem

Error:

15:27:30 + west sign -t imgtool -- --key <key>.pem

What could this be related to?

[mbolivar-nordic]

The imgtool header size is the "text section offset", which is determined from the Kconfig symbol CONFIG_TEXT_SECTION_OFFSET. Indeed, 0 is less than 32.

I would check the CI build directory's zephyr/.config file and make sure the Kconfig symbol is defined correctly. If not, then there is a problem with the way the application is being built in CI.

So, indeed the CI .config says CONFIG_TEXT_SECTION_OFFSET=0 whereas it's CONFIG_TEXT_SECTION_OFFSET=0x200 on my desktop. And I have found the issue. I forgot to commit the change that added the CONFIG_BOOTLOADER_MCUBOOT=y option ;)

I ran into this problem as well with Zephyr 2.4.0

TEXT_SECTION_OFFSET has been renamed to ROM_START_OFFSET

The default value of 0x200 for that has been removed in commit 3b66422
