Despite numerous reinstalls nrfjprog fails with the error code nrfjprog DLL load failed.  Command line was nrfjprog -f NRF52 --readcode test1.hex.  Windows 7 64 system.

Hi,

What is the full (verbatim) error message?

Can you run the nrfjprog command with the "--log" option added at the end, then provide the resulting log file (named "log.log")?

Hi,

No,  I am unable to run the log command.  Despite changing permissions I receive this error message - No logging will be possible since nrfjprog.exe has no write permission

Hi,

There was a permission issue with an earlier version of nrfjprog, but that one was fixed two years ago. I assume that you have been installing the latest version, e.g. v10.2.1 (part of nRF Command Line Tools with same version number.)

As part of the installation process, you get asked about installing J-Link V6.44e. It is important to accept this as well, as the J-Link software from Segger is what communicates with the programmer MCU on our DK.

Can you check that the install directory of nrfjprog is in the "path" environment variable? Standard location for 64 bit windows is "C:\Program Files\Nordic Semiconductor\nrf-command-line-tools\bin". You can also check that the following files are all present in that directory:

Hi, confirmed these files are in the bin directory and are the most current versions.

Hi, is this the error you're getting: "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."  There can be several reasons for this error, have you tried with other commands, different programmer, different PC, etc?
