TMS320F28388D: F/W update of hundreds of product at once

Tool/software:

Hi,

Customer is using 280039 as DCDC controller and 28388 as main controller.

Now they update f/w trhough JTAG or EasyDSP for each 280039.

1 28388 controls hudreds of 280039 so much time is spent for f/w update.

Customer would like to update it at once through CAN.

Could you guide for this request?

Thanks.
