This is a quick little blog post for how to install QEMU for ARM on Debian 7.0 (Wheezy).
Installing Toolchains🔗
Edit /etc/apt/sources.list and add
deb http://emdebian.org/debian/ stable main
deb http://ftp.us.debian.org/debian/ squeeze main
The squeeze repo is for the package libgmp3c2 that is unavailable on wheezy.
Install the emdebian public key
# apt-get install emdebian-archive-keyring
# apt-get update
Install ARM toolchains
# apt-get install linux-libc-dev-armel-cross libc6-armel-cross libc6-dev-armel-cross binutils-arm-linux-gnueabi gcc-4.4-arm-linux-gnueabi g++-4.4-arm-linux-gnueabi
Installing QEMU🔗
Install QEMU
# apt-get install qemu qemu-user-static
Optional: Install QEMU GUI
# apt-get install aqemu
Hello ARM🔗
Time to test everything is working.
helloarm.s
.text
.globl _start
_start:
mov r0, #5 @ Load register r0 with the value 5
mov r1, #4 @ Load register r1 with the value 4
add r2, r1, r0 @ Add r0 and r1 and store in r2
stop: b stop @ Infinite loop to stop execution
Assemble, Link, Build
$ arm-linux-gnueabi-as -o helloarm.o helloarm.s
$ arm-linux-gnueabi-ld -o helloarm.elf helloarm.o
$ arm-linux-gnueabi-objcopy -O binary helloarm.elf helloarm.bin
Setup flash.bin
$ dd if=/dev/zero of=flash.bin bs=4096 count=4096
$ dd if=helloarm.bin of=flash.bin bs=4096 conv=notrunc
Launch QEMU
$ qemu-system-arm -M connex -pflash flash.bin -nographic -serial /dev/null
There should now be a (qemu) prompt, type info registers and should see something like this
R00=00000005 R01=00000004 R02=00000009 R03=00000000
R04=00000000 R05=00000000 R06=00000000 R07=00000000
R08=00000000 R09=00000000 R10=00000000 R11=00000000
R12=00000000 R13=00000000 R14=00000000 R15=0000000c
PSR=400001d3 -Z-- A svc32
R02=00000009 Register 2 has the value 9 in it so everything is working.
