Since the LEON3 is a SOC it is hard to support all different configurations on a board, so the boards supported are though to support the template design of GRLIB. The LEON3FT is not supported in the current u-boot available in the sparc git repository at denx.de. Some extra steps must be taken when running the fault-tolerant LEON3, one must clear memory and registered for example so that the CRCs of the registers are correct. I have a version that supports LEON3FT available at ftp://ftp.gaisler.com/u-boot/u-boot-sparc-vxworks-1.0.0.tar.gz, currently I'm working with generating patches for the LEON3 CPU/boards, I have reworked some parts of the current LEON port. I suggest you wait one day or so until I push the patches onto the SPARC-u-boot git repo, after that I will also add the LEON3FT patches. In the meanwhile you can try the FTP link. Regards, Daniel
