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.
Think positive. If I can do it, anyone can :-)
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.
You can test that way though, and once you have that working you can get the kernel onto the internal mmc. It's best to take it one step at a time. The good thing is, even if you brick it, you can load a u-boot from the serial port and recover.
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 just want to check that you can install Debian on a VM or are running it on a PC or server somewhere. If that is the case, I can provide you instructions on installing a cross-compiler. These are packaged with Debian these days so all the hassle is gone. I don't mind installing a development environment on my Mirabox to build the kernel and sharing the instructions on how to do it, but we'll both get frustrated with the slow compile speed. You'd also need a USB drive attached as the kernel source is big.
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.
