The device nRF52832 cannot connect over SWD and generates the following error.

- VTarget = 1.767V
- InitTarget() start
- InitTarget() end
- InitTarget() start
- InitTarget() end
- ERROR: Failed to connect.
Could not establish a connection to target.

Using nRFjprog i ge tthe following error.

nrfjprog --recover --log
ERROR: JLinkARM DLL reported an error. Try again. If error condition
ERROR: persists, run the same command again with argument --log, contact Nordic
ERROR: Semiconductor and provide the generated log.log file to them.

I have attached the log.log file as well.log.log

Hi,

 

From this page, it seems that your debugger probe only works on 3.3V:

Do you have the possibility to raise the voltage on your target board?

 

Kind regards,

Håkon

Hi Keludso,

Did you solve this in the end? I am having the same issue.
