Thanks Daniel, I will definitely try your DVFlasher; I just hope the custom
board boots up without problems to begin with ;)

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

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.
Regards,
Andy
