Part Number: EK-TM4C123GXL

Hi. I am working on TM4C123GXL to develop firmware update software. while using the dfuprog.exe,

I execute the "dfuprog.exe -c" command to clear the entire flash memory.

Right after that the board is not detected with the "-e" command.

I tried to download program with ccs and fail.

So I need help in this problem. please assist me on how to communicate with the board again.

Thank you.

There are two micro USB connectors on the EK-TM4C123GXL board. One on the short (top) edge for the debug controller, the other on the longer (side) edge for the emulation device. Which connector were you attached to when you did the "dfuprog.exe -c" command?

Hi I connect the USB connector on the debug controller when I use the "dfuprog.exe -c" command.
