It is a +snapshot of work in progress and far from being completed. In order +to run it on the target system, it has to be downloaded using the +DINK32 monitor program that came with your Sandpoint system. Please +note that DINK32 does not accept the S-Record file created by the +U-Boot build process unmodified, because it contains CR/LF line +terminators. You have to strip the CR characters first. There is a +tiny script named 'dinkdl' I created for this purpose. + +The Sandpoint port is based on the work of Rob Taylor, who does not +seem to maintain it any more. I can be reached by mail as +tkoeller@gmx.net. + +Thomas Koeller + + +The port was tested on a Sandpoint 8240 X3 board, with U-Boot +installed in the flash memory of the CPU card.
