Device Manager shows "Stellaris Device Firmware Upgrade" when Tiva C TM4C123GXL Launchpad is connected

Hello Shuvo,

How are you flashing using the DFU. Are you using LMFlashProgrammer or UNIFLASH?

I am using Keil and programming using LOAD option in Keil.

Hello Shuvo,

The Stellaris In-Circuit Debug Interface is the debug interface. Do make sure that you have selected that as the emulation option in Keil. The Load of the program will happen over JTAG. The other Stellaris DFU is because you may have connected the device USB as well. If the device is empty then it will show up as a DFU.

I have connected the Launchpad in Debug Mode. I worked with launch pad flashed some programs and debugged yesterday. Everything was fine, but today the driver got corrupted and my pc does not recognize it as JTAG/COM/DFU. It is shown as "Stellaris Device firmware upgrade".I also tried some other PC the result is same.

Hello Shuvo,

Then from where is the Stellaris ICDI coming in the Device Manager?

But it is not working and as you can see in the picture it not as highlighted as "Stellaris Device firmware upgrade".

I tried to install Drivers for JTAG/COM/DFU sparately. JTAG was installed but COM port was not. When I directed Device Manger in the Driver folder then it is only shown as "Stellaris Device firmware upgrade".

No. I am a newbie in ARM.

Thank you very much, Amit. I updated the firmware and it's ok now.

hi I have the same problem exactly, can u help me ?

Hello Omar,

Is the DFU upgrade not working when you use the LMFlashProgrammer?
