Unfortunately, I think something is going wrong in the initialization with CONFIG_DM enabled for SPL because I get no text data, and it doesn't appear to boot. I tried enabling DM in SPL and using the older platdata method without success. I have disabled DM_SERIAL in SPL and tried enabling the serial debug stuff, and I get nothing. I don't have a debugger, so it's a bit more difficult to troubleshoot. The main difference between the am35 and omap3 is the memory controller, and I've tried to model the am35 after the omap3 boards I also maintain. I was hoping someone might have any suggestions on how to track down the issue. As of right now, I have OF_CONTROL working in U-Boot and with DM disabled in SPL, everything is good. adam
