Post by thread:[EE] Raspberry Pi getting Icecream Sandwich

That was my immediate thought. There should be DSI hardware available at some point, as a quick search indicates: <www.raspberrypi.org/phpBB3/viewtopic.php?f=7&t=5493> I designed a carrier board for a compilab cmx-270 at one time, and configuration was as simple as choosing the correct LCD header file, or editing it. This might be a different interface though. Should be do-able for someone with a bit of time for research. I set up a cross-compile environment on a Debian virtual machine last night and was able to actually build the kernel. Getting that onto an SD card and working will be another story. This would be to cut down the kernel size and eliminate unneeded modules and peripheral firmware to squeeze it onto smaller cards.

Unless there comes a modification to Raspbian that will use GPIO's as the touch panel/screen interface, it's probably the -ancient- DSI interface. > > I set up a cross-compile environment on a Debian virtual machine last > night and was able to actually build the kernel.

If it's not a commercial one, I might like to check it out

The PXA-270 ARM processor I used previously had a lower level interface with RGB buses and framing signals. I don't know anything about DSI buses, other than the brief wikipedia page. > >> I set up a cross-compile environment on a Debian virtual machine last >> night and was able to actually build the kernel.

I just used the existing config as in 'make oldconfig', which had me simply pressing return to accept the already set up options of the latest raspbian release. I followed instructions from here: <http://elinux.org/RPi_Kernel_Compilation> the cross-compile software for debian I got here: http://wiki.debian.org/EmdebianToolchain using: apt-get install emdebian-archive-keyring Add this to /etc/apt/sources.list: deb http://www.emdebian.org/debian squeeze main apt-get install g++-4.4-arm-linux-gnueabi This last line might not be exact, I think 'g++' could be 'gcc' and finally: make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- oldconfig or, you can make menuconfig finally make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- -k To make the kernel and modules (specified in the .config) I may do more when a need for a $35 computer presents itself.
