My V4 E3 boots using Mark's tools. There were a few issues when building :
+ The buildroot "snapshots" fails to build, you need to explicitely tell it not to use snapshots of uLibc and busybox. After than you still will get a hanging boot until you fix the inittab + u-boot "examples" fails to build here, and break the build; I commented them from the Makefile and had to make clean && make to get a working u-boot.bin + The kernel config & patch as provided in the "v1" file works, however the delta-20060227.diff generates a kernel that hangs just after decompression here, no way to make it work...
Looking forward to get that LCD + Console working :D
Would it be easy to get the rootfs, u-boot and kernel in the flash ? we are fairly close to have a system that could be used to test stuff from a nfs partition or a usb flash drive; it would save a lot of time...
