TMS320F28377D: Device Firmware Update in the field through USB

Part Number: TMS320F28377D
Other Parts Discussed in Thread: C2000WARE

Hello Everyone,

I am interested in upgrading the device firmware in the field and I know I can do it through the SCI port as follows:


where the Firmware Update decision is being taken by reading pins GPIO72 and GPIO84 as shown in the following table:


and setting BOOTCTRL register to 0x0B5A.

As SCI Firmware Update method is too slow for my purpose, I plan to use USB instead:


Is it possible to do it in an easy way, by reading pins GPIO72 and GPIO84?

Many thanks in advance,

Andreu
