Part Number: TM4C129ENCZAD
Other Parts Discussed in Thread: UNIFLASH,

Suppose you write a bin file to a Vergin state TM4C129x (shipping state) using UniFlash.

TM4C129ENCZAD and JTAG connector are connected on the board.
The JTAG connector and PC are connected using XDS110.

Please let me know if there is a manual with instructions.
Also let me know which files I need to load.

Hello Kanematu-san,

This quick start guide will walk you through the steps: https://software-dl.ti.com/ccs/esd/uniflash/docs/v5_0/quick_start_guide/uniflash_quick_start_guide.html

You would select the TM4C129ENCZAD as your device and XDS110 as your connection.

Best Regards,

Ralph Jacobi

Hi, thanks for your reply.

The Session process was over and I was about to flush the files.
I would like to know the files that should be read by TM4C129x.

Personally, I would like to do a Device Firmware Upgrade after driving the TM4C129x bootloader.

After that, I would like to make the TM4C recognize the COM port so that it can perform USB communication with the computer, and to drive the UART circuit.

Is there a file that can be read like mmWaveSDK's demo.bin? (For TM4C129x only)

Uniflash + XDS110 doesn't use bootloader functionality. XDS110 is a JTAG Debug Probe. TM4C boot loader uses non-JTAG interfaces to load program code to handle scenarios where a JTAG probe wouldn't be able to be connected to the devices.

I have no knowledge of the mmWave SDK so I cannot answer this.

I would like to perform the procedure to make TM4C recognize the COM port, but is it possible using UniFlash or CCS and XDS110 Debugger?

Also, do you feel like you can't say for sure which file is the best for the program that recognizes the COM port?

Also, does the bootloader drive have anything to do with the above process?

Yes, you just need the correct firmware file.

Your use case is an application specific ask. You can review our TivaWare examples like usb_dev_cdcserial for example programs, but I don't have a 'best program' to offer. That is for you to determine.

If you are using an XDS110 probe, the boot loader has nothing to do with the process.
