Hi Folks,
Recent Beagle (and also Panda) boards don't ship with usable NAND flash.
This makes sense, given that the chip can boot from MMC and it's a cost
reduction. U-Boot was modified to read the boot.scr from the MMC too.
But I wonder about something. A saveenv doesn't do what you want it to
with the U-Boot images I have seen. Is anyone looking at allowing
on-target boot script updates? Did I miss something that required me to
run mkimage each time I wanted to change e.g. console settings?

you can run mkimage on-target as well, no?
Sure. After booting 
But I (and I'm sure many others) are used to
using U-Boot as it was always done in the past, editing the env and
saving it before booting any kernel. If this is something that isn't
done today for Beagle, I'll see what's involved.

Jon - pleease pleeeeease do this
u-boot supports env on SD, provided you get the magic partitioning right
Can't be a lot of work then to do what I want it to Taking the card
out to change settings is just not cool enough for school.

u-boot supports env on SD, provided you get the magic partitioning right
and can you provide some guidance for it?
When I enter saveenv in the latest u-boot, the board hangs. If there is no HW support at XM then does not u-boot understand it and it could at least complain about the absence of NAND.
