It worked with the -O0 on the command line of the eth_head interface.
I had to exclude the -O0 from the command line of eth_am as it caused
the system clock of the AM to have the 37s offset.

I ran a quick test with PPS on both ends (GM/AM) and there is an
average offset of ~200us offset
between the timestamps of GM and AM (~100us with HW TS on the GM),
which is excellent for my
application (1ms would still be fine).

Thank you very much for your help.
