[nRF54L15-PDK v0.8.1] Problems with burning external boards

[zero]

Dear devzone,

I followed this instruction to use nRF54L15-PDK v0.8.1 to burn external boards. The wiring diagram is as follows:

Command line input: nrfutil device recover
The following error message appears:

There is no problem burning external boards with nRF52840-DK v3.0.2.
How can I use nRF54L15-PDK v0.8.1 to burn external boards?

BR,

Hi Asbjørn，

Now we know the problem. 1 pin SWD0_VTG in debug_out needs to be given a high level to be consistent with the vdd voltage of the external board. 

Thanks for your support
