Hi!
I have just tested this commit
commit d8bdd537220dd83912949f19ba67029bd1f11c58
Author: Lucas Stach <dev@lynxeye.de>
Date: Fri Apr 12 12:28:14 2013 +0200

This commit breaks 'usb' command --- it does not scan devices anymore, just hangs.
I have used codesourcery arm-2013.11 toolchain.
I'll try to check latest barebox from next, but just now I have no means to burn
barebox-tegra20-toshiba-ac100.img into AC100's ROM.

I haven't tested USB myself, as I'm not using second stage barebox after
u-boot and there's still things missing for USB to work on first stage.
Currently only SDMMMC is fully supported.
Are you testing exactly this commit? If so you might need to apply
431d8a247dfa63f817cda137a81dbb2244d413dc "arm: properly init alignment
trap bit", as USB might trigger an unaligned access.

You'll notice that a newer barebox won't build images for AC100 that are
suitable to burn into a boot media, because there are no BCTs publicly
available for this device. The resulting AC100 image is only useful for
starting with TegraRCM.

Um, how did you test things before? I personally haven't used second
stage for a long time. For u-boot you need to copy the barebox image
into the right spot (0x108000 for T20) and issue 'go' command. For
barebox a 'bootm /path/to/image' should do, but I won't guarantee that I
didn't break anything for second stage.

New barebox has a 'tegrarcm' command that will drop you right into
recovery mode, but obviously won't help if the machine is hanging.

How I can run barebox from barebox (u-boot) on AC100?

I work with my AC100 remotely so I can't press Ctrl-ESC on every boot for TegraRCM recovery mode.
How I can run barebox from barebox (u-boot) on AC100?

I have AC100 with u-boot burned into the flash.
Here is my AC100 test seance:
1. reset AC100 (activate reset pin for 1 second and deactivate it;
i use USB-relay board for this task at the moment);
2. wait for u-boot prompt;
3. load barebox.bin via y-modem;
4. use 'go' commmand for running barebox.
You can see that I always use barebox second stage image.

Alas! Appling of 431d8a24 does not help.
