Dear all,
My device is Voipac VMX51 machine based on i.MX51 CPU.
Previously I use Poky-Dylan-9.0.2 and custom linux kernel 3.8.5 with
Real Time patch 3.8.4-rt.
Kernel works fine if it was compiled by GCC-4.5.3 (some very old
OpenEmbedded) or GCC-4.7.2 (poky-dylan-9.0.2).
At some moment I decided to upgrade onto Poky-Dizzy-12.0.0 or
Poky-Fido-13.0.0, but encounter an issue with kernel operation.
Kernel compiled by GCC-4.8.2 or GCC-4.9.2 simply does not work at
all. No anyone message was printed at terminal after loading of
kernel by boot-loader.
To confirm issue, I intentionally compile same kernel source tree by
hands with GCC-4.7.2 and it works fine.
This is made by small script like following:
PATH=$PATH:..../yocto-build-poky-dylan-9.0.2/tmp/sysroots/x86_64-linux/usr/bin/armv7a-vfp-neon-poky-linux-gnueabi
"make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi-"
Does somebody experience similar issues with kernel compiled by old
and new compilers?
Unfortunately I does not know a way how to resolve this issue with
new compilers.
Can you recommend how to resolve issue with compiler version in
newest Poky?
Check to make sure your kernel has these two patches applied
