Any ideas why switching baudrate fails > on AXP? When 115k baudrate is specified (or no baudrate is specified) then kwboot does not inject any code for changing baudrate (as 115k is default). So it looks like that issue is with switching. I have already some more "fixup" patches for kwboot and kwbimage, which are fixing some issues which I found. So it is possible that you hit some of that issue. I will pass patches to Marek and after some testing we will send them to mailing list for review. I do not have any AXP board, so I cannot test or debug it manually.
