TM4C129ENCZAD: Why is it not detected by Device Manager even when connected via USB?

Part Number: TM4C129ENCZAD

TM4C129ENCZAD

After I wrote the TM4C129ENCZAD via JTAG connection using the following procedure, it disappeared from the device manager.

First, I did the following Setup.
Debugger and IC selection
(Debugger: USB Debug Probe)
(IC: TM4C129ENCZAD)

Next, I set the clock frequency in Settings and Utilities. (I set it to 16 MHz because I connected a 16 MHz crystal.)

The flash memory settings are also set as follows.

I loaded the image from there.
(in order of boot_loader.bin and firmware.bin)

Then, even if TM4C129ENCZAD is connected via USB, the port is no longer displayed.

However, when I loaded boot_loader.bin again, the Stellaris Device was displayed in the device manager.

Is the reason why the device is not detected from here is that the address to write firmware.bin is wrong?
