Unfortunately the Ubicom board is not supported in the mainline. So I would have to report it. Does this work on a board that supports Mainline code? I would like to eliminate that as the problem. My guess Is that there is a bug in the Ubicom port, probably dealing with The USB. I seem to be able load small files 40k with no problem. I really would like to know if anyone has loaded large files With mainline code so I can eliminate u-boot code .

Dear Dennis Kerrisk,

Please restrict your line length to some 70 characters or so.
version of u-boot was supplied by Ubicom for their chip. Every time I try t o load the file into ram from a FAT formatted USB drive, no matter what the starting address, u-boot crashes. What I need to know is this even possible? Has anyone else had this problem ? Should I attempt to try the latest version of u-boot? Ubicom has been no help at all.
Of course it is possible that U-Boot crashes, for example when there are hardware problems, or when there are bugs in the port to your board, or eventually even if you are running into a bug in common code.
If your board is supported in mainline, then running the latest version is strongly recommended.
