[U-Boot-Users] [PATCH] ColdFire: Added M5275EVB support.

[David van Geest]

I know this is a rather long email, but I want to give all the details.
Bear with me :-).

I was under the impression that the CFI patch was already included in the
f188896c... commit and that I didn't need to apply it.  I had tried the
git-rebase, but it gave me errors and then wouldn't build.  I assumed that
the git-rebase step was only required for future patches, so figured I would
sort it out later.  I should have mentioned that in my last email, I
apologize for the miscommunication.

Here's the git-rebase output:

I have applied the CFI patch from the original email using git-am, that
seems to work fine.  U-boot compiles successfully with these warnings:

I programmed the board (an M5275EVB Rev. B) with the srec using CF Flasher,
and U-Boot boots to the prompt.

However, I've run into these problems,  and I'm wondering if guys have as
well, or if I'm doing something wrong.

1)  I can't save environment variables using saveenv.  I can change them
just fine, and saveenv runs as usual, but on reset, I get a "*** Warning -
bad CRC, using default environment "

example:

->
printenv

bootcmd=bootm
ffe40000
bootdelay=5

baudrate=19200

ethaddr=00:06:3b:01:41:55

eth1addr=00:0e:0c:bc:e5:60

stdin=serial

stdout=serial

stderr=serial

ethact=FEC0



Environment size: 156/8188
bytes
-> setenv ipaddr 192.168.1.101

->
printenv

bootcmd=bootm
ffe40000
bootdelay=5

baudrate=19200

ethaddr=00:06:3b:01:41:55

eth1addr=00:0e:0c:bc:e5:60

stdin=serial

stdout=serial

stderr=serial

ethact=FEC0

ipaddr=192.168.1.101

etc.

2) Ethernet does not seem to work.  After setting the ipaddr, serverip, and
netmask variables, I run tftpboot and don't get anything but checksum
errors.  The TFTP transfer works fine with the exact same setup (router, ip
addresses, etc.) when I use dBug.  I've run Wireshark on the ethernet
interface and haven't seen a single packet from the board while running the
tftpboot command.  I've tried pinging the board, seen the packets sent on
Wireshark, and got no response.

printenv

Anything to clear this up would help.  Do either of you have ethernet and
saveenv working? Thanks for your help and your patience.
