My buildroot will build: at91-bootstrap, u.boot, linux, rootfs and scripts for u-boot tying things together, but is of course uClibc centric. >> If you have any suggestions/patches, then I would be happy to add that. > > I'll look at your patches and try to split them to smaller chunks... > Lets see if that's posible. > In the ftp location, there is only a tarball. I write a small utility which splits the diff into patches which will handle each file. Unfortunately, the way U-boot is structured, you will get files (like $(TOPDIR)/Makefile) which contains the result of many patches. I would prefer a structure where a Makefile fragment for the board is inside the board/ directory and the Makefile includes "board/*/*.mk". Much easier to add boards this way without beeing intrusive. > Best regards, > ladis Best Regards Ulf Samuelsson
