Unable to find or open JLinkARM.dll after wrong p20 SWD connection

Hi all,

i have two units of a custom board project that i made.

In the first board, I plugged the pins in the right position as you can see in the figure below, a). nRFgo find the board, and i can program it normally.

However, in the second board, i wrongly connected the pins as you can see in figure b). nRFgo cant find the board even after i put the pins in the correct position. After i clicked the Recover button, it shows the message "Unable to find or open JLinkARM.dll".

I tried to erase the dk board and the custom board but nothing worked.

I am powering both externally. My board DK version is PCA10040.

Any ideas of how can i get my board working normally again?

Thanks!

It looks like maybe the device is broken since you can't connect to it. Can you try to replace the device?

Have you tried to use nrfjprog in a command line instead of nRFgoStudio?

Hello ketiljo,

thanks for the reply and sorry for my delay to answer.

I tried nrfjprog, it returned the same message, here is the print;

Actually any command that I type returns this message.

Here is part of the log.log file :

It looks like maybe the device is broken since you can't connect to it. Can you try to replace the device?

Hi Ketiljo,

do you mean the nrf ? because i also have an AD7147 in the board.

I will replace the nrf chip, but do you think that just this wrong connection that i made is enough to broke the chip?

It depends what do you did to it then. Also make sure the power supply on your PCB is ok.

i just connected both DK and my custom board in the wrong way, as i put in the image of this ticket.
I verify my power supply always, and it is on 3.3V. The power supply is ok at least.
