Wonderful. But now, after doing the ping, u-boot's "view" of flash memory gets corrupted. For example, look at this:

Notice how the high-order 16 bits of each long word are always "0080"? This is completely bogus. However, flash has not actually been
This is not bogus. It just seems that sopmething put one of your flash chips into command mode. Assuming your hardware is stable, then some part of the code must have written some data which happened to look like a flash comand to the flash area.
If ythis is reproducable, then some parts of your PCMCIA / network / ping code write to bogus addresses in emory space. But if it's reproducable it shpould be easy to catch: just set some "data write address range" break point on the address range where your flash resides. This should catch the illegal write.
