Hi all,
Thank you for all of yours input. I was able to compile the built-in doc
driver kernel image to recognize the doc on chip. By the way, I just found
out that I had DOC Millenium not DOC 2000. Well, now I have a problem of
mounting the doc. When I try to mount doc, it tell me that "/dev/fla1 has
wrong major or minor number."
I used
mknod fla b 100 0
mknod fla1 b 100 1
mknod fla2 b 100 2
to create the special file system device.
Before I corrupt the doc filesystem, I have notice that its major is 100 0
for fla and 100 1 for fla1. Are there any temporary block device major and
minor that the diskonchip? Basically, I just wanted to be able to mount my
doc and switch out my root filesystem. Any other idea to help me mount the
diskonchip would be appreciate. Thanks again, guys.
Ky
P.S. Has anyone create a diskonchip rescue disk for your embedded box?
