Hi,

Commit fd9c7cbfe446 ("scripts: Add common library functions")
intorduced the usage of the common library functions to imx-image,
which breaks the HAB USB image generation within barebox. Signed images
are still generated fine:

I have attached the .config I used to test this, you'll need the i.MX
cst tool in your path and the environment configuration to point to
certificates. The ptx devel certificates
https://git.pengutronix.de/git/ptx-code-signing-dev were what i used
for testing.

I assume this is the same error that has been fixed in "scripts/common:
fix write_file when opened with mmap", however imx-image implements its
own xwrite helper and opens files itself, so there is a mismatch there

Thanks,
