40W is a sign the boot rom is not finding what it wants on the SD card..
So starting with the basic's.. On what system are you running the
netinstll "mk_mmc.sh" script? ubuntu/debian/fedora/etc,
vmware/paralles/native?
sudo fdisk -l /dev/sdb would also be handy..
Regards,
Scott for reference:
sudo ./mk_mmc.sh --mmc /dev/sdb --uboot beagle_cx --distro quantal-armhf
http://pastebin.com/BWW8yu9H
bootlog: (debian-installer is redirected to the dvi/hdmi monitor so
not much on serial)

(ignore the zippy2 and the ancient Beagle name, this was just a board
i had at home in the office..)
Regards,
Funny I now get this same issue after doing nand erase on my C4
I built with Vmware
lazarman@ubuntu:~$ lsb_release --all
No LSB modules are available.
Distributor ID: Ubuntu

lazarman@ubuntu:~$ dpkg --print-architecture

I used these instructions http://eewiki.net/display/linuxonarm/BeagleBoard#BeagleBoard-SetupmicroSD%2FSDcard
sudo fdisk -l /dev/sdb produced

The SD card that I had booting Ubuntu no longer works after the nand erase

LOL!!! that is so screwed up!!.. There is NO way that’ll ever boot… I don’t know who to blame VMWare or ubuntu. I’m installing ubuntu raring on a fresh disk, so i won’t be able to confirm anything till the install finishes…
Regards,
So now I am trying to understand why the old card that worked and booted Ubuntu before I did the nand erase No longer boots
here is it
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/sdb1 * 63 144584 72261 c W95 FAT32 (LBA)
/dev/sdb2 144585 31535594 15695505 83 Linux
lazarman@ubuntu:~$
It “was not” booting from your sd card before:
Texas Instruments X-Loader 1.4.4ss (Sep 22 2010 - 16:12:19)
Beagle Rev C4
Reading boot sector
Error: reading boot sector
Loading u-boot.bin from nand ← “nand; aka both MLO and u-boot.bin where loaded from nand”
u-boot on the other hand has no issues reading your partition that the bootrom could not boot…
Regards,
As a follow up to the beagleboard group, Mark please actually follow the directions as is and stop using VMware…
The directions for just fine with Ubuntu Raring as is:

(used a pre-built u-boot binary as sleep was more important at the time of testing)
