TM4C1294NCPDT: I WANT TO Program TM4C1294NCPDT on custom board to XDS110 like LP-AM243 Evaluation board

I connected it as below.

PC --- j-link --- TM4C1294NCPDTT3R PC[3:0]
PC ---TM4C1294NCPDTT3R USB0 (PL[7:6])

I flashed boot_loader.bin in 0x0000.0000 using UNIFLASH.

And Load Image & Verify Image results in UNIFLASH are as below.

But, I couldn't find which address I should flash firmware_3.0.0.26 to...

Currently, I have the results below in J-Link Commander.

But, Windows PC didn't detect TM4C1294NCPDTT3R USB in device manager.

And, xdsdfu result as below.

what should I do?

I did it as shown in Flashing boot loader section as below URL, but PC couldn't detect it in the device manager.

I suggest using xdsdfu to flash the firmware. 

After you successfully flashed the bootloader, power cycled the target, and re-connect the cable, if you run xdsdfu, it does not find any XDS110 devices?

Okay, I found it and flashed boot_loader.bin & firmware_3.0.0.26.bin.

Now, How can I make TM4C1294NCPDTT3R as XDS110?

If the hardware connections are correct, then flashing both the firmware and bootloader should be all that is needed. 

Did you base your custom board design off another TI Launchpad/EVM that has an onboard XDS110? 

Yes, I designed the circuit the same as the LP-AM243 evaluation board.

Can I use this as an XDS110 now?

How can I check if it has flashed normally?

I tried to debug AM2431 in custom board. The following error occurred in CCS

I connected the USB to TM4C1294NCPDTT3R-USB0,

but the device manager does not detect it with the port as shown below, but only recognizes it in DFU mode.

This would indicate that the bootloader is not working as expected. Typically this could be due to a corrupted bootloader. 

Was the XDS110 found by xdsdfu after flashing the bootloader and then you used xdsdfu to flash the firmware and then the failure occured?

To be exact,

TM4C1294NCPDTT3R was not recognized at first,

so I flashed boot_loader.bin to 0x2800 using UNIFLASH.

After that, The device has since been recognized as xdsdfu,

and downloaded firmware_3.0.0.26.bin.

However, when I flash boot_loader.bin with xdsdfu, it pops up as below..... "Found 0 devices"

This is odd. You typically flash to address 0x0.

Since you have debug JTAG access to the TM4C1294, please try flashing the bootloader by connecting CCS via JTAG to the TM4C1294 device and loading the boot_loader.axf via debugger program load option. This step is documented in the "Flashing the bootloader" section under "Option 2" in the XDS110 document in resource explorer: https://dev.ti.com/tirex/explore/node?node=A__ALFqIj4dX6S.TZRERoSphA__xdsdebugprobes__FUz-xrs__LATEST

Okay, I flashed boot_loader.bin to address 0x0.

I tried to load the boot_loader.axf in CCS. The result shows an error as below.

I can explain the last message about AutoRun. The debugger tries to auto-run to the target to "main" after program load. If there is no "main" in the program, then the target will just continue to run. This is not an issue if there is no "main".

The error before that could be troublesome. What is the full error message?

If you halt the target where are you halted?

And if you shut down CCS and power cycle, does xdsdfu detect the XDS110? And if so, can you flash the firmware via xdsdfu successfully and still have xdsdfu detect the XDS110?
