Honored Contributordid you rebuild the kernel with,
make make romfs make linux image ? What is your boot message now? May be you have to add busybox sleep, and wait several seconds for usb disk to be detected before mount usb. sleep 15 mount -t vfat /dev/sda1 /mntHonored Contributormake
make romfs
make linux image ?
what is your boot message now?

--- Quote End --- Sorry,hippo. I can't solve the problem. The mount command always be executed before the usb disk be detected. my step: 1. add the mount command into vendors/Altera/nios2nommu/rc . 2. make menuconfig busybox-->[*]sleep 3. make 4. make romfs 5. make linux image Is there any problem? Thank you.
Honored Contributoradd "make -C user/busybox clean" after step2.
boot uClinux, run "busybox", to see what you have built in busybox. What is your rc now?
