Dear Casperites,
Unfortunately my problem was not resolved so quickly. Upon running the 'run
new root command', I received the following issue when attempting a y-modem
connection via minicom:
## Ready for binary (ymodem) download to 0x04000000 at 115200 bps...
CCCCCCCCCC Timed out
xyzModem - Cksum mode, 0(SOH)/0(STX)/0(CAN) packets, 20 retries
## Total Size = 0x00000000 = 0 Bytes
............................................................
............................................................
.......................e
Erased 512 sectors
Zero length ???
Then, whether this was right or wrong to do (I'm new to using this device
and using FPGAs at all), I exited and reset minicom and shutoff the Roach2
using the power button on the front of the device. When I went to turn it
on, my kernel was messed-up:

Wrong Image Format for bootm command

=>
Following the instructions from this Casper thread
<https://www.mail-archive.com/casper@lists.berkeley.edu/msg06085.html>, I
tried resolving the kernel image-issue by running the 'run tftpkernel'
command. I received a timeout error during the running of this macro:
=> run tftpkernel
Waiting for PHY auto negotiation to complete... done
ENET Speed is 1000 Mbps - FULL duplex connection (EMAC0)

Retry count exceeded; starting again
(This 'retry count exceeded' error happens until the program times-out; I
posted the above snippet of printout rather than the full-printout for the
sake of space).
I've made sure to setup minicom exactly as described in this document
<https://docs.google.com/document/d/1tqw4C6uZ6EULl1OykTFL_vQTnK52UBr0aYqTg44E5wg/edit>
.
At this point, I'm at a loss for what to do. Do any of you all have
suggestions? Thank you Jason and Shanquan for your help thus far.
Best,
Alec
