I'm getting a data-abort exception every time i access the FEC ethernet device from u-boot; it happens using tftp or just ping.

With the same source everything works fine just switching the compiler.
I'm using u-boot 2016-07, almost not customized except for a pin used to keep the board up.
For now I've tested with:
arm-poky-linux-gnueabi-gcc 9.2 -> FAIL
arm-poky-linux-gnueabi-gcc 7.3 -> FAIL
arm-poky-linux-gnueabi-gcc 6.4 -> OK
all the toolchain are generated using yocto and are know to be working correctly.
U-boot is compiled with:

without environment variables affecting compilation, build host is arch linux just updated, I've tried also in an ubuntu 16.04 chroot
but with the same result.
Any clue?
Regards.

Hi
Have a look here:
https://www.yoctoproject.org/pipermail/yocto/2018-March/040486.html
So either update your U-Boot to something newer, cherry-pick the mentioned commit from upstream U-
Boot or pin the compiler to gcc 6.4.
