Re: Trasnferring u-boot to P2 730

[Kevin Hilman <khilman@mvista.com>]

It's been a while since I've done this, so I don't remember the details, but 
when I was at TI, here's what we did to put u-boot on boards with sysboot.

The 'sysboot' bootloader that is flashed on the board has the ability to flash 
new images over the serial port.  There is a windows command-line tool that is 
used to communicate with sysboot during bootup in order to (re)flash the 730. 
I forget what that tool is called.

Then you take the binary you want to flash, and add a small header to it 
(includes, offset into flash, size, etc.)   Then you pass this image to the 
windows tool and power on the board.

I don't know if that tool ships as part of the 730 kit, but you should ask your 
TI FAE for it.
