Hello,
I have an arm64 odroid c2 board. If I build u-boot with the current OE
5.3 gcc it hangs at kernel load time. If I use 4.9 gcc it works fine. A
5.3 built kernel boots fine with a 4.9 built u-boot.
The vendor supplied u-boot is hacked up and am leaning it that direction
as the culprit so I am looking for data points.
Is anyone using a current u-boot with 5.3 gcc on an arm64 machine? if
so, any special tweaks to get that combo to work?
kind regards,
Armin

I am using one ARM 64 SoC with GCC 5.2 at this moment and it works
fine. What U-Boot version is the fork based on?

I hit the same thing and ended up using their prebuilt bootloader to
get it up for testing. There is a big C++ ABI change with gcc 5.x
(I've been using 5.3.0 for a while now) and the gold linker is much
less tolerant of underlinking than bfd is. That said, their u-boot is
funky but not actually that old, and they also have a blob 1st-stage
that is only provided as a binary.
Their wiki:
http://odroid.com/dokuwiki/doku.php?id=en:c2_building_u-boot
says to checkout branch odroidc2-v2015.01 but I didn't dig into the
commit history to see when they last pulled from upstream. The error
I get with 5.3.0 looks like their u-boot/include/linux stuff is just
way too old for gcc5 (since they're still using a 3.10 kernel fork
probably). Their build also blows up with gcc-4.8 - can you say
brittle-hard-dep on gcc 4.9?

Please try to use GCC 5.2 and see if it makes any difference. The BSP
I am referring to is currently using it and it is working fine.
The forked version is the same. Of course, it may have changes which
hides or solve the issue but it is a hint anyway.
