The Adafruit Metro M0 and M4 have a socket for connecting to a SWD cable built-in - you can connect (and disconnect) a SWD cable quickly.
|
|
Remove the small plastic cap cap from the SWD socket on the Metro. |
|
|
Then, connect the SWD cable from the J-Link to the Metro. |
|
|
Once the Metro is wired up, plug the J-Link into a USB port on your computer and wait for the status indicator LED to turn green.
Then, plug a USB cable into the Metro, this is required! |
