Hi everyone, a good news for you. Linux in running successfully on qemu-omap3. Following is the screenshot.

However, MMC/USB/audio/LCD display/keyboard emulation are not ok . I will work on it.

In the following I will give you some informations of how to run qemu-omap3.

1. checkout qemu-omap3 from svn. Tag v0.01 is working.

svn checkout http://qemu-omap3.googlecode.com/svn/tags/v0.01 qemu-omap3

Or you can download it from http://qemu-omap3.googlecode.com/files/qemu-omap3-v0.01.tar.bz2 .

2. make qemu-omap3

cd qemu-omap3
./configure --target-list=arm-softmmu
make

qemu-system-arm will be generated in directory qemu-omap3/arm-softmmu.

3. download the x-loader/u-boot/kernel image.

cd qemu-omap3/arm-softmmu
wget http://qemu-omap3.googlecode.com/files/image-v0.01.tar.bz2
tar jxvf image-v0.01.tar.bz2

4. download the rootfs from beagle board site.

wget http://beagleboard.googlecode.com/files/rd-ext2-8M.bin

5. make nand flash image

cd qemu-omap3/arm-softmmu
cp ../bb_nandflash.sh .
cp ../bb_nandflash_ecc .
./bb_nandflash.sh x-load.bin.ift beagle-nand.bin x-loader
./bb_nandflash.sh u-boot.bin beagle-nand.bin u-boot
./bb_nandflash.sh uImage beagle-nand.bin kernel
./bb_nandflash.sh rd-ext2-8M.bin  beagle-nand.bin  rootfs
./bb_nandflash_ecc beagle-nand.bin 0x0 0xe80000

6. run qemu-omap3

./qemu-system-arm -M beagle -mtdblock beagle-nand.bin

7. During the graphical emulation, you can use the following keys:
Ctrl-Alt-f
Toggle full screen
Ctrl-Alt-n
Switch to virtual console 'n'. Standard console mappings are:
1
Target system display
2
Monitor
3
Serial port
Ctrl-Alt
Toggle mouse and keyboard grab.

Using Ctrl-Alt-3 to switch to beagle board serial port. You can see x-loader and u-boot booting message. When u-boot command line appears, type the following commands.

OMAP3 beagleboard.org # nand read 0x80000000 0x280000 0x400000
NAND read: device 0 offset 0x280000, size 0x400000
4194304 bytes read: OK
OMAP3 beagleboard.org # nand read 0x81600000 0x680000 0x800000
NAND read: device 0 offset 0x680000, size 0x800000
8388608 bytes read: OK
OMAP3 beagleboard.org # setenv bootargs 'console=ttyS2,115200n8 ramdisk_size=8192 root=/dev/ram0 rw rootfstype=ext2 initrd=0x81600000,8M nohz=0ff'
OMAP3 beagleboard.org # bootm 0x80000000

Linux will boot with some debug information of qemu-omap3. Enjoy it.

Update: 2010-02-20

I am too busy to do omap3 emulation these days. The guy at maemo has made great improvement in qemu omap3 emulation. Go to this page for more information. I do not know whether the steps in this artilcle can be used in the new version of qemu-omap3.

    I am unable to do a checkout of the omap3 directory for getting the source code to build it. SVN returns an error that PROPFIND could not connect to the server. But, i can see the dir and its contents on the web site. Do u have a tar zipped copy of this source dir which i can copy through my browser?

    thanks

    Hi satheesh, You can download it from http://qemu-omap3.googlecode.com/files/qemu-omap3-v0.01.tar.bz2 . Thanks.

    Hi,
    I am using ubuntu host machine for this purpose.
    I'm getting some error while launching
    ./qemu-system-arm -M beagle -mtdblock beagle-nand.bin -nographic

    All other steps worked flaw-less but while launching I'm getting this error

    @Badarinarayan
    Hi Badarinarayan, that's because script bb_nandflash.sh is not compatible with ubuntu dash. Two tips for resolving this problem. You can try ANY of these.

    1. dpkg-reconfigure dash
    choose Install dash as /bin/sh? with NO.

    2. change bb_nandflash.sh
    #! /bin/sh
    ->
    #! /bin/bash

    Wish it helps you.

    hi yajin,
    I am able to build and run the qemu-arm-system exec, but on Linux boot up, the processs hangs. I tried 3 times - in the first attempt it hung with a kernel panic and in the next two attempts it hangs after few "block prints"related to "omap3_cm_dp114_update". Following is the full log (sorry for pasting it here as i can't find an option to attach a file!). Any info to debug this would be very helpful. I compiled qemu using gcc ver 4.1.1 on Fedora.

    Hi satheesh,
    Firstly, I suggest you using gcc 3.4 to compile qemu.
    Secondly, the bootargs in u-boot is wrong.
    You must set bootargs as following:
    setenv bootargs 'console=ttyS2,115200n8 ramdisk_size=8192 root=/dev/ram0 rw rootfstype=ext2 initrd=0x81600000,8M nohz=0ff'
    Please notice initrd=0x81600000,8M not initrd=0x81600000,3M.

    hi Yajin,
    Sorry for the trouble. Looks like the issue was related to a typo that i did with the bb_nandflash_ecc command. Now I am able to reach the Linux prompt. I want to check whether the network interface support has been added. Primarily, I am trying to see whether I can run tftp from QEMU-beagle and get my app executable from another PC and then run the executable. If its not ready yet, how can i run an app as of now? Do i need to rebuild the rootfs for Linux with my app in one of the directories?

    Great work from your side!

    thanks
    satheesh

    The USB network emulation is not supported right now. So you can not use tftp to upload applications to rootfs. Currently, you should rebuild rootfs although it's boring......
    I am working on MMC/SD and USB emulation. After finishing, you could put applications into emulated SD card image or using usb net to upload your appliation.
    Thanks for your interest in qemu-omap3.

    Do you have the source for the busybox RD file system which you are using for qemu-omap3? I couldn't find the source code on Beagle Google site.
    Sorry for the repeated trouble!

    It works! I just followed your instructions and it worked.

    I did get the following errors when starting qemu:

    I also got the following from the boot loader:

    ***** Warning - bad CRC or NAND, using default environment

    However, linux still booted up.

    Now, what's next? Can I fire up X windows?

    Thanks for the qemu / omap3 info. I am able to get the OMAP3 system up using the instructions above.

    What I need to do is re-compile the kernel and bring the system back up. Can you provide me with information about how to rebuild the kernel ?

    I have an actual OMAP35x board and tried to restart the qemu/omap3 system using the default kernel from the system and with one I rebuilt. The qemu system will hang right after the kernel load (using bootm). Also, I have tried with a kernel I build from OpenEmbedded.org for OMAP.

    Basically, I just need to know where the source is for your original kernel and build instructions so I an reproduce it.

    Thanks,
    David

    Hi Yajin,

    I was trying to build the qemu...I am running into an error whenever I try to do a make for qemu-omap3...It gives me an error saying:

    make: *** No rule to make target `../libqemu_common.a', needed by `qemu-system-arm'. Stop

    I use the kernel from http://www.beagleboard.org/uploads/2.6_kernel_revb-v2.tar.gz.

    make CROSS_COMPILE=arm-none-linux-gnueabi- distclean
    make CROSS_COMPILE=arm-none-linux-gnueabi- omap3_beagle_defconfig

    And then diselect MMC/I2C/USB support in kernel. It may works.

    Hi Mark, not yet right now. Currently qemu-omap3 is not complete and many works need to be done first.

    Hi, I am trying to use the linux framebuffer driver with the beagle emulator. The driver is present in the kernel listed above. Moreover, when i write into the framebuffer device (/dev/fb0), it actually writes to the right physical memory space, but nothing appears on the display. I verified the OMAP display controller registers through the QEMU monitor and they seem to be well initialised. Where could be the problem?

    Maybe the display controller emulation is not correct. You can add some debug information into qemu and see what has happened.......

    I found what could be a bug in the display controller emulation (hw/omap_dss.c). After the fix, i managed to install DirectFB and SDL on the ramdisk and to make them work.
    Thank you for the tip .

    Hi yajin:
    I compile qemu and do everything in your user manual.
    But when I boot, qemu hang up at picture of beagle board.
    So I press ctrl+alt+3, and input
    "OMAP3 beagleboard.org # nand read 0x80000000 0x280000 0x400000
    OMAP3 beagleboard.org # nand read 0x81600000 0x680000 0x800000
    OMAP3 beagleboard.org # setenv bootargs 'console=ttyS2,115200n8 ramdisk_size=8192 root=/dev/ram0 rw rootfstype=ext2 initrd=0x81600000,8M nohz=0ff'
    OMAP3 beagleboard.org # bootm 0x80000000
    I can see the below
    Uncompressing Linux..........................................................
    .......................................... done, booting the kernel.
    Then system hang up.
    why?
