U-Boot versions

Hi...

I just noticed that the instructions for board validation have 2 versions of u-boot. On the download page at http://code.googlegroups.com/p/beagleboard/downloads/list they are described as:

• u-boot_revc_v3.bin - u-boot for REV C
• u-boot-f_revc_v3.bin - u-boot to flash on NAND

What are the differences to these files? Do you normally need to have a special u-boot.bin for the flash and a different one for the SD card?

Btw... I also notice that these scripts and wiki instructions for rewriting the flash use a command "nand unlock" which doesn't seem to exist on my board. I always get a usage message.

Sorry, I mistyped that link. It was supposed to read: http://code.google.com/p/beagleboard/downloads/list

Hello...

Does anyone have any insights on this? Can the same u-boot image be used on the Beagleboard's NAND as on a MMC/SDHC card, or are there necessary differences?

Thanks...

Somebody has to know about this. Please?

I'm not sure what the differences are because I'm rather new, but
these two pages should help:

http://code.google.com/p/beagleboard/
http://code.google.com/p/beagleboard/wiki/BeagleboardRevCValidation

I'd say just stick with what is outlined there and it should work.

yeah, I started there and was hoping someone could explain the
differences between the 2 versions of u-boot that can be put on the
validation image MMC/SD card, particularly if it is significant or not.

while reading threads here, it sounds like people are typically
flashing the NAND with the same one they use on an SD card, so this
raises the question in my mind.

I'm not sure what the differences (if any) are
between the two files. In general, there is
nothing special about apps that run from NAND
rather than from SD, and I'm pretty sure I've run
the same uboot code from both places. I think the
"to flash on NAND" version might automatically be
copied to NAND by one of the scripts, but I'm not
sure why that would need to be special.
The files are slightly different (comparing the
binaries), but I don't know why. I would just
give it a try with one of them and see if there are any problems.
