I have a Tiva C TM4C123GXL Launchpad EK and I'm trying to figure out how to us the DFU. I'm able to flash the device via CCS in debug mode and using the LM Flash Programmer but I'd like to be able to see how it will work on my board and we will not be using the JTAG. I thought I could simply flash the boot_usb program and after reset see the device on the Device USB port and not just the DEBUG USB port using the dfuprog application. On our board we plan to use the USB to load user programs and not necessarily have the JTAG support.
I can use the Bulk example to run the echo program through the Device USB port. Is it possible to also program the flash from this port? If so what am I missing? I want to be able to run the dfuprog app to access this USB port. What does this require?
