Comment 2 Fabrice Fontaine 2021-01-08 11:01:26 UTC

This error raised with gcc 10 should have been fixed by https://git.buildroot.net/buildroot/commit/?id=198db470a73c14191915f8374362bc2a8b08c2bf (applied to master in April 2020)

Comment 3 Yann E. MORIN 2021-07-03 17:05:08 UTC

Anil, All,

As stated by Fabrice, this is now fixed for the dtc package he pointed at.

The traces you pasted are supposedly from the Linux kernel. Since there
are so many versions of the Linux kernel, we can't easily bundle a patch
for the dtc copy bundled in the kernel sources. You will have to backport
the upstream commit e33a814e772cdc36436c8c188d8c42d019fda639, using
BR2_GLOBAL_PATCH_DIR.

Regards,
Yann E. MORIN.
