Hi,

I'm trying to put RTAI kernel in a TS-7260 and I'm getting the following kernel 
panic:

Kernel panic: VFS: Unable to mount root fs on 1f:01

The command that I'm passing to RedBoot is:

exec -c "console=ttyAM0,115200 root=/dev/mtdblock1"

I have already tried many different versions of RTAI kernel from Embedded ARM 
(ts8, ts9 and ts11) and everyone show the same error.

For information, I'm using ymodem to transfer the kernel to redboot with the 
command:

load -v -r -b 0x00218000 -m ymodem 

Can anyone help me?

I'm also having the problem already described at this forum about the 
resolution of usleep (10ms). But I really need something that sleep my program 
with a resolution of, at least, 10us, because I have to generate a very specif 
wave at DIO1.

Thanks,
Ronan.
