Hi
End of January a change was made in the poky meta-layers.
Change:
https://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=97c882303e444d994c1f5be8c4d9a9472496d3ef
After these change, it was not any longer possible to build u-boot (u-boot-ti-staging_2020.01.bb from meta-ti).
I solved these issue, to add the following statements in my bbappend file:
B = "${WORKDIR}/build"
do_configure[cleandirs] = "${B}"
Please check it and maybe update the u-boot-ti-staging_2020.01.bb file.
Best regards
Christoph
