Peter, I understand what you are saying, but that assumes all of my custom board hardware is working and that I have u-boot working already working. I'm talking about the first time I attempt to put u-boot (or any flash image) on the board; since my flash is different than that of the DVEVM, how do I do that? I can't use the DvFlasher as that was meant specifically for the AMD28LV256 flash on the DVEVM. TI told me that I have to modify the DVFlasher code to work for my flash which can take me a while since there's no support.
Yeah, I understand if I have u-boot already working on my custom board, I'm pretty much far along in bringing up my board. That's why I wonder if anyone has tried using a boundary scan tool to flash their brand new board (we have a boundary scan setup expert) and not having to deal with writing software (DVFlasher) to flash the initial u-boot image.

Worked fine for us. As long as your flash is CFI compliant this should work with nearly every flash chip.
