[Direct Test Mode] The failed result of for nRF54L15 via SDK v3.0.0

[Paul Lin]

Hi Support team:

I am new for using the Nordic Design kit of nRF54L15-DK. 

And I would like to use the app "Direct Test Mode" v2.4.2 built-in the "nRF Connect for Desktop" v5.1.0 on my Windows OS.

But I followed up the instruction to install the SDK with v3.0.0 and burn the .hex into the board and power-on still show the error message.

Cannot communicate with the device. Make sure it is not in use by another application, that the correct serial port has been selected, and that it uses firmware compatible with Direct Test Mode.

Hi Support Team:

Do have any recommended samples for Direct Test Mode?

Hi Support Team :

This is the file I compiled from Samples/Direct Test Mode and burn into nRF54L15 but the App "Direct Test Mode" still can`t communicate it.
