I have a TM4C1294XL launch pad that will not exit the firmware update mode.
Setup:
The Board is connected directly to a computer over usb only, nothing else is connected to the board. I am using windows on a mac in a virtual machine (using parallels), It has worked perfectly for me. Normally when plugging the board into my mac, it is discovered as a"In-Circuit debug interface #X" with x being the particular number of the board I am using and I forward the hardware to my virtual machine. I have never had an issue doing this over the past year.
Circumstances:
I was trying to upload a program and CCS locked up, I force quit CCS and unplugged the board. Now the board will not program in CCS anymore when starting a debug session(I get the error: frequency out of range), but it recognized as a In-Circuit Debug interface by my mac and windows. I thought that I might have screwed up the debugger interface so I tried to do the xdsdfu utility to update the firmware for xds110 using xdsdfu -m and xdsdfu -f firmware.bin -r . Now the device won't exit firmware update (DFU) mode. I do have another 1294XL programming with CCS now. (It did not want to at first, but programed it with the MAC OS CCS 'hello world' program and it now is recognized and programing in my windows environment.)
I realized now that the firmware I loaded is most likely the wrong firmware and that is probably why it won't exit DFU mode. Is there a way to salvage this board?
