I do use PlanetCore to boot the system. Basically the only funtionality in my own custom boot loader with this board is to carry the image of the Linux kernel, decompress, and launch it. I have disabled all the initialisation code since it was previously written for another board, and PlanetCore does all the initialisations anyway. I didn't care to erase PlanetCore from the flash just yet, since I can just as well develop the real initialisations later with the custom board. PlanetCore itself is not usable for booting any other Linux kernel than the pre-installed one. It just allows me to launch some launcher of the Linux kernel... Probably it's the launcher that does the tricks to make Linux run correctly. > Of course, if you are doing your own boot rom and have a board to > bring up, > you should have invested in something like a BDI2000 long ago because > it will > have paid for itself many times over by the time you are done :-) It > would have > also allowed you to debug this problem rather quickly. > You are right, this would be a lot easier with a good debugger. I just have delayed purchasing it since I wasn't previously sure if we'd use the PowerQUICC II family or not. I already have Lauterbach for 8xx, but the Linux community seems to prefer the BDI2000. Do you know if it fits better in Linux development? At least it seems to be a lot less expensive than a new Lautherbach license for the 82xx family.
