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.
