[beagleboard] Unable to use mmc 0:1 for fatls

[mhoyt]

Hi,

I've got a REV C2 Beagleboard that I haven't fiddled for a while and
decided to get back up and running the latest Angstrom Demo. I'm
using a 4GB SD card that worked before.

I'm following the various guides on getting Angstrom running but I
seem to be stuck on some sort of problem might be related to my mmc.

Here is what I see at boot (holding the user button):

When I try to list the files on the MMC card I get this:

OMAP3 beagleboard.org # fatls mmc 0:1

** Unable to use mmc 0:1 for fatls **


Any advice on how to proceed?

Much obliged.

Mike

Did you do 'mmc init' before the fatls?

regards,

Koen

[mhoyt]

Nope.

OMAP3 beagleboard.org # mmc init
mmc1 is available

OMAP3 beagleboard.org # fatls mmc 0:1

23976 mlo
23976 x-load.bin.ift
205364 u-boot.bin

3 file(s), 0 dir(s)

Thanks! Do I need to issue an mmc init command each time I power up?

Mike

[mhoyt]

nevermind. dumb question. I see I can do a set bootcmd.

Thanks for your help.

I am confused. I've followed the steps but the command "mmcinit" does
not appear to be a valid command. "mmc init" is valid. I tried
changing the boot command to include the space but it seems to be
entering an interactive mmc command.

Is there an updated newbie guide that reflects these changes or I am
doing something wrong?

Thanks.

Mike

bootm - boot application image from memory

Usage:
bootm [addr [arg ...]]
- boot application image stored in memory
passing arguments 'arg ...'; when booting a Linux kernel,
'arg' can be the address of an initrd image

Sub-commands to do part of the bootm sequence. The sub-commands must
be
issued in the order below (it's ok to not issue all sub-commands):
start [addr [arg ...]]
loados - load OS image
cmdline - OS specific command line processing/setup
bdt - OS specific bd_t processing
prep - OS specific prep before relocation or go
go - start OS

mmcinit is the *old* form of the command. in newer versions of
u-boot, it's now "mmc init".

I did a printenv and noticed a typo in my bootcmd variable. I fixed it
and it seems to initialize the mmc correctly but now it won't load the
Angstrom image:

Any newbie-type mistakes that would lead to this?

thanks.

I got it working. My boot partition had a copy of u-boot.bin from the
setup_boot.sh script that I experimented with. I copied over the u-
boot.bin that I downloaded with the Angstrom root file tar ball. I
also noticed I didn't have uImage on the boot partition (small
problem). I also copied that over and rebooted the BeagleBoard and
its working.

Thanks for the help and sorry for cluttering up the group with my
stumblings...

I will stumble just as much and like you, I need to get back to fiddling
with my Revision C4 Beagleboard. So I feel a little like I'm back to
learning how to read myself. I'm planning to order the Trainer board
this week and the Beagleboard XM when it becomes available.
