The standard firmware for the BDI2000 does not provide this feature. But I know that Abatron provided such a solution as part of their excellent support - within less than a day AFAIR. I guess this solution is still available. > My current plan is to use custom Flash programming code running in SDRAM, > but it would be nice if there was a tool that let me bypass this process. We encountered similar problems before; this is one of the very few cases where I think that starting with a version of U-Boot that gets loaded to RAM first actually makes sense. > Again, I hope this message isn't too far off-topic. Thanks for any help. You are welcome.
