Hi,
I�m almost done porting U-boot to a custom HW platform but I have a problem getting the Ethernet port to work correctly. I�m using a 857T with a Realtek 8201BL transceiver. If I run U-boot and press a key so I get to the prompt and then type tftp I see the following behavior.
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 change RINV back to normal and run again.
The tftp transfer then completes.
I can now issue a tftp transfer over and over without 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 the pin-configurations.
Has anybody seen this behavior before or have any ideas.
Thanks,
Brian Rasmussen
