-Root filesystem with BusyBox
-----------------------------
-
-This challenge is derived from our "Tiny filesystem lab". Look
-at this lab for further instructions.
-
-- First, we will setup networking between the QEMU emulated
- machine and the host.
-
- The first thing to do is to create a /etc/qemu-myifup (for example)
- script that will bring up a network interface. Here are its contents:
-
-#!/bin/bash
-exec /sbin/ifconfig $1 192.168.100.1
-
- Of course, make this script executable:
- sudo chmod +x /etc/qemu-myifup
-
- As you can see, the host side will have IP address 192.168.100.1.
- We will use 192.168.100.2 for the target side.
-
-- Then, create an empty "nfsroot" directory
- Install the nfs-kernel-server
- Modify /etc/exports to export the new directory
-
-- Then, you will need root privileges to run QEMU this time,
- because of the need to bring up the network interface:
-
-sudo qemu-system-arm -M vexpress-a9 -m 128M -nographic -kernel u-boot -sd sd.img -net tap,script=/etc/qemu-myifup -net nic
-
- Also note the new net options:
- -net tap: creates a software network interface on the host side
- -net nice: adds a network device to the emulated machine
-
-- In QEMU, interrupt the countdown in U-Boot modify bootargs to
- setup the target IP address to 192.168.100.2
- and mount the root filesystem through NFS using the directory you created.
-
- Don't forget to run "saveenv"!
-
- Still in U-Boot, you can now run "reset" to reboot and attempt
- to boot Linux.
-
- If you need to kill QEMU, you'll have to do it with "sudo":
- sudo killall qemu-system-arm
-
-- Once the NFS root filesystem is mounted, proceed by compiling
- BusyBox with your toolchain, installing it, and eventually
- test the http interface and switch to shared libraries,
- following the normal lab instructions.
-
- To enable job control, instead of adding "ttyS0" to /etc/inittab,
- you will use "ttyAMA0", which is the serial device used for
- our emulated board.
