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?
Best wishes.
