You can access the mounted usb disk as normal file.

So just include stdio.h and stdlib.h should work.

You can add the mount command or other initialization into vendors/Altera/nios2nommu/rc .

it will be installed to romfs/etc/rc .

Hi,hippo.

I have added the mount command(#mount -t vfat /dev/sda1 /mnt)into vendors/Altera/nios2nommu/rc ,but it need to execute mount manual all the same,and there is nothing under the path of /mnt .

please help me!

thak you!

did 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 /mnt

Sorry,hippo.

I can&#39;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.

add "make -C user/busybox clean" after step2.

boot uClinux,

run "busybox", to see what you have built in busybox.

What is your rc now?
