It works and I am able to create combined kernel + root fs fitting in 4 MB flash, kernel is gzipped as u-boot seems support only that and rootfs lzma-compressed. Trouble is u-boot does not like my images, so I need to investigate that, which does not seems to be easy now... Has anybody some experience in this area? There is GPL compliance tarball from TP-link with some u-boot directory in it, but is it possible to build it somehow under FreeBSD? All in this tarball seems to be 'just Linux'... Regards, Milan
