Dave (and the list)- Thanks for the insight. I believe I have everything I asked about figured out, but I am still not having any luck getting the new u-boot to load. I see the processor go and start fetching the u-boot image off the flash and it comes out of reset, then soon after a hard reset is issued. I can not wrap my head around why the new u-boot (2009-8) will not boot versus the old u-boot (1.1.3). I didn't really change anything to get the stock Freescale u-boot to boot on this board except change the flash size information. One interesting thing running the new u-boot code is I don't ever see it try to read the BCSR (on CS1). Speaking of, why did the BCSR get mapped to 0xE2400000 from 0xF8000000? I know I'm being vague, but I've trying so many things and had no luck, so I just wanted any ideas from the crowd. Oh, and your paper you linked to earlier is a wealth of information! It takes reading a lot of Freescale documentation over and over again to grasp some concepts you summed up nicely in a few pages. Thanks in advance!
