UNIFLASH: dslite: select device when using --mode cc13xx-cc26xx-mass-erase

OK, seems like it's not supported as of last year. https://e2e.ti.com/support/wireless-connectivity/bluetooth-group/bluetooth/f/bluetooth-forum/914862/uniflash-how-to-use-uniflash-cli-to-mass-erase-cc2652rb-with-locked-debug-interface

BTW, The reason I'm asking is that I'm having trouble with the erase functionality in the "regular" mode when there is already some firmware on the board (even if the JTAG interface is wide open) and I was hoping to use the cc13xx-cc26xx-mass-erase to properly reset the chip into a clean state.

Executing the following command:
> "c:\ti\uniflash_6.3.0\deskdb\content\TICloudAgent\win\ccs_base\DebugServer\bin\DSLite" flash --verbose --config uniflash_L40007FS.xml --before Erase

For more details and examples, please refer to the UniFlash Quick Start guide.

The help text for this mode does not list a way to specify which board to use, and when 2 boards are connected, it selects one apparently at random. How can I specify which of the 2 connected boards to erase?

Please see:

Alternatively, can I get it to perform the erase on all connected boards?

Only on a per device basis.

Thanks

Sorry, but I don't see how the link answers the question. It describes how to make a configuration XML, and that works for other commands, but the cc13xx-cc26xx-mass-erase subcommand does not take a --config parameter:

c:\>dslite --mode cc13xx-cc26xx-mass-erase --help
Executing the following command:
> "c:\ti\uniflash_6.3.0\deskdb\content\TICloudAgent\win\ccs_base\DebugServer\bin\DSLite" cc13xx-cc26xx-mass-erase --help

For more details and examples, please refer to the UniFlash Quick Start guide.

Options:
  -d [ --debugProbe ] arg Debug Probe (XDS110, XDS100v3, XDS200)
  -h [ --help ]           Print this message.

oops, ah, yes.

Are you able to normally connect to the devices or is the mass erase to restore a device that you are unable to connect to (like unlock a device)?

It's the latter - sometimes the debug probe isn't able to connect, resulting in an error message like the one shown in my first reply to this post. I haven't figured out what causes this problem, so I was hoping to just work around it with the mass-erase command.

(this is for an automated test setup by the way, which is why I'm trying to do everything through the command line)

Aha! That worked. The Linux version has similar files, so I suppose it will work there as well. Thanks!

Great!

By the way, I filed an enhancement request to officially support the workaround in the product. Tracking link: https://sir.ext.ti.com/jira/browse/EXT_EP-10498

Thanks
