The old 5282 stuff doesn't work all that well.(At least I could never get it too) As far as that old post,
(http://sourceforge.net/mailarchive/message.php?msg_id=11392569)
Zack is correct that the structure is wrong, but there are other problems with the old code as well.
We have modified u-boot to work correctly with our 5282 based module..perhaps you could incorporate it into your design instead of starting from scratch?
Regardless, the following link is a good place to start: ftp://SoM:sompublic@ftp.emacinc.com Here you'll find lots of stuff specifically for the 5282, including Zach and EMAC's u-boot code modifications. There's also datasheets for our SoM-5282EM module, which could certainly save you some time designing with the 5282.....
I'll try to break out individual stuff into patches and get it into the main tree at some point, but compatibility with the main source tree's flash drivers is still an issue as I understand it.
thx, NZG.

Hi,
My name is Daniel Alomar, I'm from Barcelona, and I'm working with a Motorola Coldfire 5282 (AVNET) board with U-Boot as a bootloader.
I was using an older version from Alan Carvhalo modified to this board and it works ok (0.4.0 release). Now I was trying to port to the newest version (1.1.2) and I achieve my goal, but I've one little problem: With this loader, I can't connect through TCP. If I try to upload another version through tftp, I've some Timeout errors:
MFC-SERRA> tftp 20000 loader.bin; protect off ff800000 ff81ffff; erase MFC-SERRA> ff800000 ff81ffff; cp.b 20000 ff800000 $(filesize) TFTP from server 172.27.26.9; our IP address is 172.27.26.202 Filename 'loader.bin'. Load address: 0x20000 Loading: TX timeout T TX timeout T TX not ready ... TX timeout
Retry count exceeded; starting again TX not ready TX timeout TX not ready ... TX timeout (I type Crtl+C) Abort MFC-SERRA>
I was searching through the list, and I found one solution (http://sourceforge.net/mailarchive/message.php?msg_id=11392569) that made U-Boot didn't work at all.
Does anybody know how I can solve this question?
