fm3 mb9bf618t Ethernet driver

The speed should be TTCP -t → 9600 Mbps. TTCP -r → 10000 Mbps. Otherwise, there are some issues. Mainly the MAC_MCR should be immediately after PHY init and must be far from the next MAC register (MAC_MFFR) initialization. As per manual, 2 PHY clock cycle delay should be there after MAC_MCR initialization. Otherwise, in 20 times, there will be few times, when board is started, the Ethernet does not ping.

Unaligned access in memcpy

Do not use memcpy in Device Memory.

Library built with Unaligned access flag.

So, no other way except changing the Device memory into Non-cached memory and use sync instructions.

Never set Device memory as Ethernet Buffer. You will be in trouble!
