Hi,
I'm using nrf52840, try to program using Jlink SWD programmer but fessing some issues.
over hardware connections are like below.
When I try to Connect J-Link, I get an error that says "Failed to connect to target. No idcode detected. Please check connection and Target Interface Type".
so could you please tell me this is hardware problem or software problem, if this error solve using software then could you please provide a steps to solve connection error.
Hello,
You can try to update nrf command line tools to see if that helps:
https://www.nordicsemi.com/Products/Development-tools/nrf-command-line-tools/download
Try to run "nrfjprog --recover".
Also try to connect nRESET directly to VDD in case it's been accident set as output low.
Kenneth
Hello Kenneth,
Try to run "nrfjprog --recover".
could you please describe more how i can run "nrfjprog --recover" ?
Hi,
Example:
Can you try to connect RESET pin directly to VDD in case you by accident have enabled/configured this pin as output low. You have not by accident swapped SWDCLK and SWDIO?
Kenneth
Hello,
I can measure voltage like below.
VDD-3.3V
SWDIO-3.3V
SWDCLK-0V
SWO-1V
RESET-3.3V
You have not by accident swapped SWDCLK and SWDIO?
No, its not swapped accidently.
Have someone reviewed your schematic and layout? Do you see the same on all boards or only some boards? Have you tried a different j-link? Do you have any other nRF52 board you can use for test?
Kenneth
i have sent schematic earlier.
I got this problem in only 2 board out of 10. this 2 board earlier works fine but after some test its not connect with jlink.
In all likelyhood something have happend to the boards, it could be some mechanical or electrical damage that now cause the boards to now not work (e.g. ESD). What can you tell me about the handling of the boards? Is it possible they might have been damaged during use?

Kenneth
i think you are right. its looks like damage during test. But we are using ESD band to remove static.
Please find attached log file, if u find any error on it.

I suggest "nrfjprog --recover --log"

nrfjprog --readcode dump.hex --clockspeed 500 --log
