Hi, I want to upload the code to external nrf52832 chip(which is on the custom-made PCB) using nrf52DK board.
First, I tried to check uploading the nrf52832 chip on nrf52DK board (nrf52DK-to-nrf52DK) using nrf52DK board following the figure below.
And it worked properly.

Next, I tried to upload external nrf52832 chip on my PCB with the same way. However, the error appeared.

I only soldered nrf52832 chip and tried to upload code. Should I assemble all the other parts(ex) crystal, inductor) to upload the code?
Is there any solution for this, please?
