Hello guys,
I'm having trouble booting from an SD card generated from DVSDK 4.03 on my Technexion TDM-3730 (basically, a DM-3730) board. The SD card is a 8GB SanDisk simply created by running this from the DVSDK directory:
sudo ./bin/mksdboot.sh --device /dev/sdc --sdk /home/myuser/dvsdk
It boots just fine until it tries to mount the root filesystem, then I get a classic "VFS: Unable to mount root fs":
[ 4.456390] Waiting for root device /dev/mmcblk0p2...

Any suggestion would be appreciated...what puzzles me is that the mmcblk0p2 seems to be listed as a valid partition in the error message from the kernel. Could it be an SD card problem as mine is a 8GB one? Also I have a revision G1 hardware it that matters.
Thanks!
