Dear Sebastian,

I am sorry for late reply due to customer meeting.

That's great process in your side.

I am still working for porting i.MX6Q FEC driver after I added FreeBSD's i.MX6 FEC driver code on rtems-libbsd.

But, Because my custom board have different PHY chip(RTL8201E), I did't port FEC drier on i.MX6Q board. I used fdt loading method, too.

If possible, please could you let me know i.MX6Q hardware board information which you are successful for porting FEC driver ?

On referencing, I am working to port SMP for i.MX6Q.
At this time, current version is not stable. I am looking technical reason.

Best Regards,
JunBeom Kim

I found the problem. The i.MX7D needs a 64 byte receive buffer alignment in contrast to the 16 byte alignment required by previous FEC versions.
