Can not connect icarus 9160 with JLink of 9160 DK board and flash.

[kitchen]

I'm trying to leverage the asset tracker project form nordic 9160dk to actinius icarus 9160 board, i use tagconnect 2030 to connect P19 of dk and icaurs, but the jlink cannot connect the board. I already register the board at actinius I/O, i'm sure i connected the tagconnect tightly. but here is the output of JLink:

Hi,

 

Have you set the "VDDIO" dip switch into 3V position? It is located just to the right of the power switch on the nRF9160-DK.

i'm sure i connected the tagconnect tightly.

If used often, these cables will degrade over time. Do you have another tagconnect to test with?

The dk number is visible via nrfjprog --ids, but any --memrd or --recover command fails.

Could you try to run recover in a loop via a batch script?

:loop
nrfjprog --recover -f NRF91
goto loop

 

Then power cycle your external board (icarus) and see if this is able to recover it.

 

Kind regards,

Håkon
