Andy,
I wrote the DVFlasher host application and the UBL that is associated with it. The UBL is written to support CFI compliant Flash devices that adhere to either the AMD or Intel command set. I have personally tested with both types of chips, as the newest DVEVMs come with Intel Strataflash devices, instead of the older AMD devices. If your custom boards have serial connections, then this is an attractive way to go. In fact a good initial sanity check for a custom board is to set your DM644x device to UART boot mode and verify that you see BOOTME messages on the serial line. SPRAAI0 and SPRAAI4 have details of how to use the serial interface for basic diagnostics. The latest DVFlasher is available from the DVEVM update site. Regards, Daniel Daniel J.

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.
