QEMU MIPS
=========
-Qemu is a full system emulator. See http://www.nongnu.org/qemu/
+Qemu for MIPS is based on the MIPS Malta board. The built Malta U-Boot
+images can be used for Qemu and on physical hardware. The Malta board
+supports all combinations of Little and Big Endian as well as 32 bit
+and 64 bit.
Limitations & comments
----------------------
-Supports the "-M mips" configuration of qemu: serial,NE2000,IDE.
-Supports little and big endian as well as 32 bit and 64 bit.
-Derived from au1x00 with a lot of things cut out.
-
-Supports emulated flash (patch Jean-Christophe PLAGNIOL-VILLARD) with
-recent qemu versions. When using emulated flash, launch with
--pflash <filename> and erase mips_bios.bin.
-
-
-Notes for the Qemu MIPS port
-----------------------------
+The memory size for Qemu is hard-coded to 256 MiB. For Malta Little Endian
+targets an extra endianness swapped image named *u-boot-swap.bin* is
+generated and required for Qemu.
Example usage
-^^^^^^^^^^^^^
+-------------
-Using u-boot.bin as ROM (replaces Qemu monitor):
-
-32 bit, big endian
+Build for 32 bit, big endian:
.. code-block:: bash
- make qemu_mips_defconfig
- qemu-system-mips -M mips -bios u-boot.bin -nographic
+ make malta_defconfig
+ make
+ UBOOT_BIN=u-boot.bin
+ QEMU_BIN=qemu-system-mips
+ QEMU_CPU=24Kc
-32 bit, little endian
+Build for 32 bit, little endian:
.. code-block:: bash
- make qemu_mipsel_defconfig
- qemu-system-mipsel -M mips -bios u-boot.bin -nographic
+ make maltael_defconfig
+ make
+ UBOOT_BIN=u-boot-swap.bin
+ QEMU_BIN=qemu-system-mipsel
+ QEMU_CPU=24Kc
-64 bit, big endian
+Build for 64 bit, big endian:
.. code-block:: bash
- make qemu_mips64_defconfig
- qemu-system-mips64 -cpu MIPS64R2-generic -M mips -bios u-boot.bin -nographic
+ make malta64_defconfig
+ make
+ UBOOT_BIN=u-boot.bin
+ QEMU_BIN=qemu-system-mips64
+ QEMU_CPU=MIPS64R2-generic
-64 bit, little endian
+Build for 64 bit, little endian:
.. code-block:: bash
- make qemu_mips64el_defconfig
- qemu-system-mips64el -cpu MIPS64R2-generic -M mips -bios u-boot.bin -nographic
+ make malta64el_defconfig
+ make
+ UBOOT_BIN=u-boot-swap.bin
+ QEMU_BIN=qemu-system-mips64el
+ QEMU_CPU=MIPS64R2-generic
-or using u-boot.bin from emulated flash:
-
-if you use a QEMU version after commit 4224
+Generate NOR flash image with U-Boot binary:
.. code-block:: bash
- # create image:
- dd of=flash bs=1k count=4k if=/dev/zero
- dd of=flash bs=1k conv=notrunc if=u-boot.bin
- # start it (see above):
- qemu-system-mips[64][el] [-cpu MIPS64R2-generic] -M mips -pflash flash -nographic
+ dd if=/dev/zero bs=1M count=4 | tr '\000' '\377' > pflash.img
+ dd if=${UBOOT_BIN} of=pflash.img conv=notrunc
-Download kernel + initrd

- qemu_mips_kernel.patch
- initrd.gz
- vmlinux
- vmlinux.bin
- System.map
-
-Generate uImage
-^^^^^^^^^^^^^^^
+Start Qemu:
.. code-block:: bash
- tools/mkimage -A mips -O linux -T kernel -C gzip -a 0x80010000 -e 0x80245650 -n "Linux 2.6.24.y" -d vmlinux.bin.gz uImage
-
-Copy uImage to Flash
-^^^^^^^^^^^^^^^^^^^^
+ mkdir tftproot
+ ${QEMU_BIN} -nographic -cpu ${QEMU_CPU} -m 256 -drive if=pflash,file="$(pwd)/pflash.img",format=raw -netdev user,id=net0,tftp="$(pwd)/tftproot" -device pcnet,netdev=net0

How to debug U-Boot
-------------------
In order to debug U-Boot you need to start qemu with gdb server support (-s)
-and waiting the connection to start the CPU (-S)
+and waiting the connection to start the CPU (-S). Start Qemu in the first console:
.. code-block:: bash
- qemu-system-mips -S -s -M mips -pflash flash -monitor null -nographic -net nic -net user -tftp `pwd` -hda ide
+ mkdir tftproot
+ ${QEMU_BIN} -s -S -nographic -cpu ${QEMU_CPU} -m 256 -drive if=pflash,file="$(pwd)/pflash.img",format=raw -netdev user,id=net0,tftp="$(pwd)/tftproot" -device pcnet,netdev=net0
-in an other console you start gdb
+In the second console start gdb:

-Debugging of U-Boot After Relocation
