Hi
I recompiled the kernel for my TS-7260 to support v4l
and loaded the image using tftp. I used the kernel
src and modules from TS and crosstools compiled for
linux provided by seiner.com. To compile I did:
make ts7200_config
make menuconfig (added v4l)
make dep
make vmlinux
make modules
and then tftp'd vmlinux over to the board.
The problem is that I get this error on boot:

I don't think I messed with the root filesystem but
I'm new to this.
Here's what Redboot shows:
RedBoot> fconfig -l
Run script at boot: true
Boot script:
.. fis load vmlinux
.. exec -c "console=ttyAM0,115200 root=/dev/mtdblock1"
My hunch is that I don't have support for the NAND
flash. How to I make sure this gets compiled in? Is
there something in menuconfig (or elsewhere?) that I
missed?
Any suggestions appreciated.
Ollie
