TM4C1294NCPDT: Have trouble enabling the USB port of tm4c1294ncpdt

Part Number: TM4C1294NCPDT
Other Parts Discussed in Thread: EK-TM4C1294XL

Hi!

I am new to TM4c1294NCPDT and I am trying to enable the USB port (not the debugger usb port). I don't know how to enable it. At first I think after I load the boot_loader to it the usb port will be enabled. But it didn;t work. Can you please tell me how to enable it or where should I start?

Thanks a lot!

    Hi,
    Please try the usb_stick_update example. This example should be first loaded into the flash acting as a bootloader. Once running, it will read an application named FIRMWARE.bin from a usb stick and program it into another area of the flash memory. The usb_stick_update example can be found under <Tivaware_Installation>/examples/boards/ek-tm4c1294xl/usb_stick_update. The usb_stick_demo is an application that needs to be renamed to FIRMWARE.bin and first saved to your usb stick by PC. You will then insert the USB stick to the usb port on the board. The usb_stick_update will then read and program this FIRMWARE to the flash.

    Hi!
    I am sorry but I can't quite understand the meaning of "The usb_stick_demo is an application that needs to be renamed to FIRMWARE.bin and first saved to your usb stick by PC."
    regards,
