[U-Boot-Users] Help with TSEC on MPC8343

[Johnson, Justin M (GE Infra, Energy)]

I ported U-Boot 1.1.6 to a custom board I am having trouble getting the TSECs to work.  I am using an MPC8343 with the reduced interface, and a National Semiconductor DP83848 PHY.  When I do a ping, I get the following result:

=> ping 192.168.0.100
Trying TSEC0
Speed: 100, full duplex
Using TSEC0 device
TSEC0: tsec: tx error
TSEC0: tsec: tx buffers full
ping failed; host 192.168.0 is not alive
=>

When I try with the Freescale evaluation board running U-Boot 1.1.3, it works, so I am fairly confident of the network IP addresses, etc.

=> ping 192.168.0.100
Speed: 100, full duplex
Using Freescale TSEC0 device
host 192.168.0.100 is alive
=>

I am new to all of this and an not sure what I am forgetting to set up.  My board's config file is based on the MPC8349ADS.h file.  I have read the README file and searched the mailing list, but haven't found (or completely missed) what I need.  Below are some register values at the time the Tx Error occurred.  Any help will be greatly appreciated.
