Working > kernel configurations and qemu command line options are welcome! I tested it with kernels and rootfs'es from pokylinux.org autobuilder, but they may have stopped working in the meantime. :( When I last tried to build a kernel for spitz outside OE, I had to apply ASoC patches from opensource.wolfsonmicro.com because ASoC was not in mainline yet (2.6.19 I think). > > Are there any other options to get both framebuffer and sound support > with qemu-system-arm? Not any of those which have full Linux mainline support. Otherwise there is the PalmT|E (cheetah), MusicPal and Neo1973.
