Booting from mmc - how?

GoogleGroups
1

First I booted with the mmc inserted (FAT32 - MLO and 7 other files on
partition 1), the Angstrom demo untar'd to the ext3 partition 2, but
it always boots from the NAND. RESET/USER switches don't have any
impact.
I login as root on the serial console and get a bash prompt, the mmc
is mounted as /media/mmcblk0p1 and /media/mmcblk0p2.
I have followed other posts, setenv doesn't exist - it's bash.

The DVI display is OK, but the keyboard is not enumerated via a hub
attached to the EHCI port (self-powered or USB powered - 3 different
hubs tried).
Any pointer gratefully appreciated.

For your first problem:

  1. Make sure you hold down the USER button for a second or two after you press RESET.
  2. If X-Loader isn’t running from the SD card then its not called MLO or isn’t correctly signed.
  3. If X-Loader can’t load U-Boot from the SD card it will load it from NAND (either way it says where its loading it from)
  4. U-Boot then loads the linux kernel based on environment variables, so you might want to check what those are set to.
  5. If all else fails you can always run the command “nand erase” from U-Boot to erase everything in NAND. It definitely won’t be booting from NAND then.
  6. The setenv command is almost certainly supposed to be typed into U-Boot. To access U-Boot you need to be connected up to the serial cable and press return a few times when it says to interrupt automatic boot.
  7. If this doesn’t solve the problem then please post the serial output during boot up.

For your second problem:

  1. Not sure… should be fine… what does lsusb -v show…? Make sure you don’t connect any low/high speed devices directly to the port as it then causes the EHCI port the be inactive until you reboot.

No change there.

2. If X-Loader isn't running from the SD card then its not called MLO or isn't correctly signed.

First I checked on a Windows XP box that it was called "MLO", then I
reformatted partition 1 as FAT32 under Windows XP, copied MLO, u-
boot.bin, u-boot-f.bin, uImage.bin, x-load.bin.ift, boot.scr,
normal.scr and ramdisk.gz that were save to MyDocuments. Files exactly
as I typed them should case be a problem.

3. If X-Loader can't load U-Boot from the SD card it will load it from NAND (either way it says where its loading it from)

Booted from NAND, MMC card not inserted.
# setenv bootargs 'console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw
rootwait'
# setenv bootcmd 'mmc init;fatload mmc 0 80300000 uImage;bootm
80300000'
# savenv
Powered off, inserted the MMC card and booted as recommended.

You only need MLO, u-boot.bin and uImage (or uImage.bin if you prefer) on the SD card. The rest being there shouldn’t hurt though… not sure why X-Loader isn’t seeing the SD card… I would replace the MLO and u-boot.bin with ones from the Angrstrom demo folder (they may well be more up to date), see: http://www.angstrom-distribution.org/demo/beagleboard/

You cannot use XP to format the SD card. You need to use a special format program that can be found here:

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

It formats the card in such a way that the ROM internal to the OMAP processor can detect it. You also must copy MLO as the first file onto a freshly formatted card.

I am using the files from that directory.

Thanks, I shall try that.

MLO is also the first file copied on the MMC.

This implies that partitioning and formatting under Linux as
documented doesn't do the job though it appears to, so a mix of
Windows and Linux is necessary. Windows is as rare as rocking-horse
manure around here so I have to travel.
With SP27213.exe I picked LABEL1 FAT32 for formatting and it
reformatted the whole disk, erasing the ext3 partition. I shall go
back and try again - may be I missed something.

If you change the c/h/s as instructed, it does.

I started all over again doing all the preparation under Linux. It
seems I was using the wrong uImage (2.6.28) that didn't work with the
Angstrom distribution, couldn't find /lib/modules/2.6.28-omap1 -
uImage-2.6.29-r37-beagleboard.bin did the trick. Still USB problems,
not seeing the powered hub, keyboard and mouse on the EHCI port.

"modprobe idmouse" invalid module format with the modules that are a
part of Angstrom-Beagleboard-demo-image-glibc-ipk-2009.X-
stable-20090612--beagleboard.rootfs.tar.bz2 .
Wonder if it needs modules-2.6.29-r37-beagleboard.tgz instead.

12

The modules package finally fixed it.
The mouse is working and I used it with the on-screen keyboard to do
the setup.
The keyboard is still not being enumerated, but I shall look at that
after some much needed sleep - there were some keyboard selections
during setup, but lsusb doesn't show it.
