Thanks for getting back to me. I hope you are right. What little I have found via searches with Google were not comforting, to say the least.
I can't do a boot from the sdcard for this application as I will probably be using it for something else. I think that is why I was thinking I need to do something with uboot. I don't have a cross compiler, although I have heard there might be one at Globalscale. I have built cross-compilers but not since I did one to build m68000 code for a NeXT from an i486... needless to say, it took several days to do the 3 compiles to generate it. I hope the world has gotten easier in the ensuing two decades. I'm working on some stuff where I have to be quite conservative as I hope to put it into a cubesat someday if we can raise the cash for it. -- +---------------------------------------------------------------+ | Dale Amon Immortal Data | | CEO Midland International Air and Space Port | | a...@vnl.com "Data Systems for Deep Space and Time" | +---------------------------------------------------------------+
