BB C4 doesn't boot after nand erasing

My C4 has not been used for a long time. After reboot, it got stuck in kernel as follows,

[ 21.720794] regulator_init_complete: incomplete constraints, leaving VAUX3 on
[ 21.728179] regulator_init_complete: incomplete constraints, leaving VDAC on
[ 21.736297] twl_rtc twl_rtc: setting system clock to 2000-01-01 01:51:11 UTC (946691471)
[ 21.744812] Waiting for root device /dev/mmcblk0p2…

Then I erased nand completely at boot prompt. Since then, there are only werid characters and 40W even if user button is held down.
I tried some, but no luck. Can anyone recommend how to get it work from a bare board?

I just found my USB port is connected to network, maybe boot got stuck on USB. But it still hangs at the same place in kernel.

Have you verified that your sd card actually has a 2nd partition?

Yes, I have and installed file system. I have reformated SD card. I tried another card, it has the same problem. Bit it works on XM.
I used 2.6.32.

My C4 still got stuck there. It was returned for RMS. After I received it, I found it didn’t reboot. Since I got XM, I put it aside. I wonder
if there is hardware failure on mmcblk0p2, it used to work with my previous uboot, uImage. I tried ramdisk.gz, it seems O.K. but I can not access mmcblk0p2. I can not see it in /dev. The latest Demo u-boot, uImage 3.0.17 doesn’t get my C4 boot, Can anyone point me somewhere to download MLO, uboot and uImage working on C4

Just for verifcation, give this a try:

Do you have those for kernel 2.6.32?

Did they fix your problem?

Your own your own with that...

After

git clone git://github.com/RobertCNelson/stable-kernel.git
cd stable-kernel
git checkout origin/v3.7.x -b v3.7.x
./build_kernel.sh

I just saw zImage other than uImage. That doesn't work

Okay, that was odd.. Usually users scroll down a little farther:

http://elinux.org/BeagleBoardUbuntu#Quantal_12.10_armhf

and download the demonstration image, that:

1. Formats the SD card.
2. Installs known good bootloader
3. Copies Root File system
4. Installs known good mainline kernel..

Still no joy!, I trid old rmadisk.gz, it gives me some clues, It seems MMC has problem from boot message
