If that command is writing a file, the written file should remain in
WORKDIR, not UNPACKDIR. I suspect the SRC should probably therefore be
changed but not the BINARY?
WORKDIR still isn't cleaned between builds of a recipe I assume? While
migrating to UNPACKDIR gets rid of patches that were once in SRC_URI but
aren't anymore (or other files for that matter), using WORKDIR as a
temporary directory between tasks is going to be an issue depending on
how the other tasks are going to behave. If the logic using the file is
the same as the logic for creating the file then it shouldn't be an
issue. But if the logic using the file is just checking whether the file
exists, then using WORKDIR is an issue since it won't be cleaned between
builds of the same recipe.
Correct.

Maybe we should go for ${B} instead?
${B} would probably be an improvement, yes.

Thank you for the valuable feedback. Following your suggestions I modified the patch to use B for UBOOT_ENV_BINARY. I sent v2 of the patch a few minutes ago. Best regards, Leon


Cheers,

Richard
