Just FYI, it seems that template is currently broken, as eCos won't build 
successfully with "ecosconfig new edb7xxx net". I'll redo it and send a 
make.out if you want, but it should be easy to reproduce.

Anyway, I got everything built OK, but it seems that more configuration is 
required. When my app starts, it hangs repeating "CS8900: Tx interrupt lost".

To gather a little more info, I set up a (different from previous) bogus 
MAC address of 0x00:0x14:0x49:0x18:0x14:0x00 using fconfig, and I enabled 
boot-time network debugging. Power up and I get several repetitions of this:

Tx event: 8

RedBoot>

The link LED is on, everything should be working I think. Is there 
something else I've forgotten?

One issue that I don't understand here is the following quote from 
< http://sources.redhat.com/ecos/docs-latest/tcpip/tcpip.3.html#pgfId=1132625 >: 
"This assumes that the MAC address is already defined in the serial EEPROM 
or however the particular target implements this; there is no (tested) 
support for setting the MAC address in this release." Does the networking 
code in eCos [not redboot] read the MAC address set by fconfig and saved in 
main flash store? If not, then how is it possible to bring up eth0 on the 
Cirrus board?
