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

[Alanarf]

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!

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?

[Alanarf]

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?

[ketiljo]

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