Hi, Ti

How to do a reflash with uniflash using the command line?

I need to use the Chip Erase (Retain sectors specified in CCFG) option.

Best regards

Preston,

In Uniflash, if you click help, it will open a page in your browser that has instructions on using the command line interface. This is the latest link it will bring you to:

Hi, Evan

I failed to download it. Do I need to connect the reset pin when I reflash Self-developed board? I currently only have SWDIO (TMS), SWDCK (TCK), GND connected to the XDS110, and 3.3V externally powered.

From the error it looks like it can't get into download mode.

Best regards

Preston,

First, it would be recommended that you test to make sure your CLI arguments work with a standard TI CC2340R5 LaunchPad. Can you check this first?

But generally, yes it is highly recommended that you have the reset pin. After you reflash, the programmer will attempt to invoke a reset. You can view the programming flow here under Section 8.2.4.

Hi, Evan

I connected the CC2340 reset pin to the XDS110, and I can reflash CC2340 after connecting it.

Thanks for the answer.

Best regards
