Hi Steve, The newest DVEVM software release 1.10.01 on the TI site has a new u-boot loader (only compiled for NOR flash, but with sources) that does fix the SW3-4 problem. It looks as if the boot loader is the only update. If you do a diff against the u-boot sources of your working version you should see the differences - when I checked it seemed they mainly changed the initialization for the internal DSP power control. It was not properly activated in the V1.10 boot loader so they gave the temporary SW3-4 workaround to set the DSP for self-boot, which as a side-effect activates the DSP power domain.
By the way: 1. Does anyone have sources for the first bootloader in NAND (the max 14 kB loader)? We only have a .bin file. 2. Does anyone know the proper U-boot configuration for NAND flash booting?

Even we can boot from NAND, our DSP algorithm can not work. Our embedded department people told me this is because we have to set SWITCH3-4 to OFF in order to boot from NAND. TI FAE seems mail us an diver to solve this, but we do not know how to use it.
