own api flashing dsp 2812

Hello,
I work on  a 2812 dsp board, I make a c# application to test it and now i
want to flash it.

On this board i have four Dsp (not interconnected), i use SDFlash with
four com port and four sdp project.

I can create a process which will launch four SDFlash.
Does SdFlash can take arguments in a command line, like this ?
\SdFlash clientprjCom1.sdp
...
\SdFlash clientprjCom4.sdp

An other idea is to create my own window working like SDFlash.
In this case, do you know if it's possible to have SDFlash source code
or informations about c++ input methods that i can call to flash dsp.

A last question, does it exist an industrial method to flash more fastly
several dsp.

thank you for your help.

Good idea.

The procedure of the bootloading of the TMS28xx is quite simple and well 
described in the application notes. There is no problem to develop it 
from scratch. You can use the resident flash API from TI or develop the 
flasher of your own.

The parallel programmer is much faster.
This could also be done with the ATE on the production line, if your 
board supports for that.
