"No device detected" in nRFgo studio (can't flash S110)

[hassan789]

Hi, I'm trying to flash the S110 onto my nrf51822 SoC, but nRFgo gives me the following error. (Also, hitting recover just gives me an error: "an error condition was detected in the JLinkARM DLL").

I am using a standalone J-Link plus debugger with only the SWD pins connected to the SoC.

EDIT: This is a brand new chip. This is the first time I am attempting to connect to it.

May be the chip is stuck. It can happen if there’s no specification in firmware about how it can come alive after reset.

Referring to the solution answered here: devzone.nordicsemi.com/.../cannot-recover-with-nrfgo-could-not-read-ahb-ap-id-could-not-connect-to-target

Try to open J-Link Commander from the start menu, and write the following:

r

w4 4001e504 2

w4 4001e50c 1

w4 4001e514 1

qc

Hope it would work. It did for me everytime.

Best,

ok, i will check this. But this is a brand new chip. This is the first time I am attempting to connect to it.

Unfortunately, I get the same issue after trying this. It did say something like "successfully written" 3 times when I ran those commands

99% chance, the line is not well connected.

check the soldering.
