Hi folks,
Happy new year 2012 to you all.
I was able to get my beagleboard c3 to work with a ubi rootfs. Details below:
ubifs in the link that you provided, but I have been using the
information in http://processors.wiki.ti.com/index.php/TI-Android-GingerBread-2.3.4-DevKit-2.1_UserGuide#Creating_ubifs_images,
3) When I attempt to load my ubifs image into memory from the mmc with
this u-boot the system hangs:
fatload mmc 0:1 0x80300000 ubisystem.img
reading ubisystem.img
[hangs forever here]
I can confirm Khr's observation that TI's u-boot hangs with above. I
tested on a beagleboard RevC3. I used the u-boot that was included in
the aforementioned Devkit 2.1 Gingerbread release. That is:
U-Boot 2010.06 (Dec 31 2011 - 21:04:15)
OMAP3430/3530-GP ES3.0, CPU-OPP2 L3-165MHz

[shows that reading 2.7MB is fine]
OMAP3 beagleboard.org # fatload mmc 0 0x80300000 ubi.img

[hangs here, waited up to 20 minutes]
(same also happens with pre-built version of u-boot provided in the
devkit release):

This issue was also posted on the e2e forum,
Booting Android from nand with ubifs root file system on BeagleBoard Rev C4 - Processors forum - Processors - TI E2E support forums
.
It would be good if someone from TI could provide feedback on the
issue. Is the inability to load a 60MB file to memory with the TI
u-boot a known issue? Khr solved that portion of the problem by using
the mainline u-boot. Is that what we should be doing?
I was able to get this to work. Here's what I did:
- same u-boot sources as before (same as prebuilt)

[ I used a different target address this time 0x8400_0000 instead of
0x8030_0000 which I had copied from Khr. I am not sure how long it
took to read it as I wasn't paying attention, probably less than 10
minutes. It would be great if someone could explain why the
0x8400_0000 address makes it work. ]
Ok, so then I went on to flash the ubi.img to NAND as follows.
OMAP3 beagleboard.org # nandecc hw 1
HW ECC [Kernel/FS layout] selected
OMAP3 beagleboard.org # nand erase 0x780000 0x39A0000

OMAP3 beagleboard.org # mmc init

[ I just wanted to test if it is able to boot off the ubi partition so
just changed bootargs rather than trying to flash xloader and u-boot
to nand as well. ]
