Subject: [Buildroot] [PATCH] arch/xtensa: xtensa little endian target requires an overlay file
Date: Sun, 4 Sep 2022 22:04:09 +0200 [thread overview]
Message-ID: <20220904200409.3153993-1-romain.naour@gmail.com> (raw)
Using a custom Xtensa processor configuration select little endian
by default. But xtensa for little endian requires an xtensa overlay
file containing a version of xtensa-config.h header for gcc setting
XCHAL_HAVE_BE to 0.
When BR2_XTENSA_LITTLE_ENDIAN is selected, we have to check if
an overlay file is provided. Error out if BR2_XTENSA_OVERLAY_FILE
is empty.
Fixes:

xtensa-buildroot-linux-uclibc/bin/ld: ldso/ldso/ld-uClibc_so.a(ldso.oS): compiled for a big endian system and target is little endian
