I am bringing up an EP9312-based prototype that is
essentially a subset of the EDB9312 design. The only
major difference is that this prototype has 16-bit
wide flash unlike the the 32-bit flash of the EDB9312.
I have modified the redboot and kernel patches to
reflect this change. I am able to successfully
download and flash kernel and ramdisk images (using
serial, not network). When I try to "exec", I don't
get a linux prompt, just what appears to be some sort
of redboot message (see the last line of the dump). I
am trying the run using a serial console.
+EP93xx - no EEPROM, static ESA, or RedBoot config
option.
No network interfaces found

What does this final line indicate? I have tried
various exec options but always get the same message.
Thanks for any help you can provide.
