Settings button next to J-Link causes "uVision IDE has stopped working"

Hi. I am using a Nordic nRF51422_xxAA (Cortex-M0) and a JLink plus. When I attempt to debug,
the message "No Cortex-M Device found in JTAG chain." and "Error: Flash Download failed -
Target DLL has been cancelled". There are a couple of problems with the first statement.
First, when I use J-Flash software, I am able to connect to the part, so I
believe the hardware to be OK. Second, this device uses a SWD connection, not a JTAG.
So, I attempt to reconfigure the Flash interface (Flash->Configure Flash Tools, Debug Tab)
"Use" is selected, as is "J-LINK / J-TRACE Cortex", then I click on Settings,
and "uVision IDE has stopped working ... Windows will close the program..." appears. The
only option at that point is a "Close program" button, which closed the IDE.

Please tell me what I am missing. Thank you.

  • Hello Dave,

    it seems that you are doing the right things. I have tested it here with MDK v5.11a (I have a nRF51822_xxAA instead of the nRF51422_xxAA) and it works. I can do the Flash download and start the debug session. Settings button works as expected. Which version of MDK are you using?

    Kind regards,

    Christopher
