Using Flash Drive as Root FS at Boot Time Fails
Okay, I'm sure there's something obvious here that I'm missing, but I can't seem to find how this should be done.
I have a flash drive that I want to mount as my root filesystem at boot time. When I'm in linux, I can run `mount /dev/sda1 /mnt`, and the kernel will mount the ext3 FS on the flash drive at /mnt with no problems.
From this I assumed I could boot my system with the kernel option 'root=/dev/sda1', but this doesn't work. My kernel has no initrd, and is booted directly by a bootloader. It has no modules, so I know that's not the issue.
The current setup that works consists of a ramdisk that the bootloader loads into RAM before booting the kernel. The kernel detects this ramdisk and the current kernel root option ('root=/dev/ram') mounts the ramdisk as the root fs with no problems.
I can see where the kernel detects the flash driveat startup, and I can't think of a reason why I couldn't just mount it as root. I can copy/paste startup logs here if necessary.
Any ideas or help would be very appreciated.
