Im almost done porting U-boot to a custom HW
but I have a problem getting the Ethernet port to
correctly. Im using a 857T with a Realtek 8201BL
transceiver. If I run U-boot and press a key so I
to the prompt and then type tftp I see the following
5 ARP requests are sent but no response is received
and it times out and tries again.
An ARP response is never received.
If I stop U-boot with the BDM and changes RINV in
GSMR_L and start again I receive an ARP request and
tftp gets called but the transfer stops.
To get the tftp transfer to continue I need to
RINV back to normal and run again.
The tftp transfer then completes.
I can now issue a tftp transfer over and over
making any changes through the BDM. Even the ARP
request works every time.
This behavior is consistent every time I reboot the
system. The only modifications made to the code are
Has anybody seen this behavior before or have any
