Using the (nearly) mainline kernel (net-next, closely tracking 3.9), one can almost build a working kernel for the Ben. "Working" here means that it gets to a shell on the serial console.
In the OpenWRT build process, a fairly large number of kernel patches gets applied. They live here: http://projects.qi-hardware.com/index.php/p/openwrt-xburst/source/tree/master/target/linux/xburst/patches-3.3 I found that just one of them is essential for getting the system to boot: 0020-qi_lb60-NAND-add-data-partition.patch I also used 0008-qi_lb60-Don-t-use-3-wire-spi-mode-for-the-display-fo.patch to get fewer complaints from the kernel. To boot a mainline kernel, I also had to override the boot command line and add init=/etc/preinit (OpenWRT traditionally had a kernel hack that added this directly to init/main.c, but I don't know if they still use this. In any case, our u-boot setup seems to expect the kernel to find preinit on its own, which it doesn't.) With this, I get to a shell and can play with ATBEN and such. Since I'm using a "headless" board, I don't know whether the screen would actually work. The absence of 0007-Add-ili8960-lcd-driver.patch in mainline suggests that it won't. Another thing that's missing is the USB driver, 0002-Add-jz4740-udc-driver.patch The rest of those 3.3 patches are mainly about NAND optimizations, audio, power saving, wireless, and assorted minor changes. I wonder what the status of all those patches is. Have they been submitted towards upstream ? If yes, have they been accepted by the respective subsystem maintainers and just haven't propagated into Linus' tree yet ? Is someone tracking them ? - Werner _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
