Running Linux for AR7 in QEMU MIPS emulation ============================================ The QEMU MIPS emulation permits running AR7 firmware without a real system. This package contains everything needed for a first start under Linux (tested with Debian). Filelist -------- flashimage.bin FLASH image with SQUASHFS (compressed filesystem) qemu-ar7.tar.bz2 sources of patched QEMU qemu-system-mipsel precompiled QEMU README this file vmlinux precompiled Linux kernel Put these files in one directory. The examples given below are started from this directory. The Linux kernel and SQUASHFS are based on OpenWrt. Other distributions work, too. How to run QEMU for AR7 ----------------------- Run QEMU from a command shell like this: ./qemu-system-mipsel -L . -kernel vmlinux -nographic You should see the boot messages from the Linux kernel and get a shell prompt after pressing ENTER. You may also try the QEMU GUI like this: ./qemu-system-mipsel -L . -kernel vmlinux If you want to connect a debugger to the emulated system, use ./qemu-system-mipsel -L . -kernel vmlinux -s -S See the QEMU documentation (part of the sources) for more options. How to compile QEMU for AR7 (not needed for first try) --------------------------- Unpack the patched QEMU sources, change into directory qemu, configure and compile with ./configure --cc=gcc-3.3 --target-list=mipsel-ar7-softmmu make How to test other firmware -------------------------- The emulation uses several locations for the firmware to run: * mips_bios.bin This file is optional. It is a binary image of the firmware in the AR7 internal ROM (located at 0x1fc00000). * flashimage.bin This file is a binary image of the FLASH. 2 MiB and 4 MiB flash were tested with images from different AR7 based routers. You will need this file if your kernel wants a filesystem in FLASH, but also if you want to test bootloaders. * vmlinux This is an elf image of the kernel to run. If you have a full flashimage (one with bootloader and kernel), vmlinux is optional. What works, what does not work ------------------------------ AR7 hardware is only emulated partially. Only the serial ports work nearly fully (they emulate a 16450 instead of 16550). Ethernet hardware emulation is partially available, but still not usable. There is a rudimentary flash emulation, so Linux detects a 4 MiB Intel flash.
