Checksum for file could not be found (scarthgap)

[Moritz Krautwald]

Hello,

I was following the tutorial [1] which basically resembles the raspberry
pi setup in meta-swupdate-boards.
Building results in this error:

ERROR:
/home/mo/projects/daccu-coprocessor/meta-daccu-coprocessor/build/../meta-swupdate/recipes-support/swupdate/swupdate_20
23.12.1.bb: Unable to get checksum for swupdate SRC_URI entry
0001-BUG-regression-checking-IVT.patchfile: file could not be found

Then it lists all paths, also the one containing the patch. The weird
thing is, that swupdate_2023.12.1.bb contains:

> require swupdate.inc
>
> SRC_URI += "file://0001-BUG-regression-checking-IVT.patch"
>
> SRCREV = "66952eff1a30701686723ff2fab0576b389620db"

So openembedded appends file resulting in the .patchfile suffix, which
does not exist on the filesystem. I am unable to explain this and could
not find any hints online. Does someone has any idea what might be
causing this?

Best regards

Do you have another .bbappend with SRC_URI:append = "file..", that means
without the required space for the append ?

Nevertheless, why are you forcing 2023.12.1 when I released 2025.05 for
scarthgap, too ?

Hello Stefano,

thank you for your answer. Indeed I had a SRC_URI:append without the
space. Adding it resolved the issue.

I did not force 2023.12.1. I even tried forcing 2025.05, but even then
the error occured, probably because it already happened while loading
all the metadata.
