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
|

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 Before Relocation
|

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
.. code-block:: bash
|
||||
|
||||
Before relocation, the addresses in the ELF file can be used without any problems
|
||||
by connecting to the gdb server localhost:1234
|
||||
gdb-multiarch --eval-command "target remote :1234" u-boot

Debugging of U-Boot After Relocation
|

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|

For debugging U-Boot after relocation we need to know the address to which

U-Boot relocates itself to 0x87fa0000 by default.
|

And replace the symbol table to this offset.
