How to add USB DFU for TM4C1294 project?

Other Parts Discussed in Thread: EK-TM4C1294XL, EK-TM4C123GXL, TM4C1294NCPDT, LMFLASHPROGRAMMER

I tried to figure out how to add USB UFD to an example TiVa project, usb_dev_bulk

Following advice on http://ww w.ti.com/lit/ug/spmu301a/spmu301a.pdf, I found bl_usb.c in TiVaware folder and added to the project.

next, I added #define USB_ENABLE_UPDATE

bl_usb.c needs bl_config.h. There is template in the boot_loader folder that requires configuration according to the target, but there is none in the TiVa tm4c1294 example folder.


Any pointer for the next step or reading?


Thanks!
