Hi All,

I wanted to let anyone trying to make a new DFU project know that there seems to be an error in the quick start guide (QSG) included with the DFU library.

Cypress Device Firmware Update (DFU) Middleware Library 4.0: Cypress Device Firmware Update (DFU) Mi...

Step 3.2 Specifies for a post build signing command to be added to the App0 project. I found that if I included this command then the the chip programming would fail saying it tried to write a part of memory it didn't have access to. After removing that step I was able to successfully setup the example.

Perhaps a CY_SECTION(".cy_app_signature") is needed but I did not go back and try to add this.

Best,

Dave

I tried the steps listed in the QSG, and it's valid to setup the dfu process in MTB2.0.

I don't notice any problem after Step 3.2 adds that command to makefile and then program the app0 on the board.

Attach my Dfu projects here for your reference.
