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?

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

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.

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:

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 Thanks for the qemu / omap3 info.
