Occasionally, you'll run into a problem where AS7 won't connect/run the target device.
Common error messages look like this:
I have yet to solidify what causes this. But, the fix is usually as simple as doing one (or more) of the following:
- Disconnect and reconnect the SWD cable from the target device and the J-Link. Wait a few seconds for the J-Link and the backagent to sync up.
- Close AS7, then re-open your project.
- If those don't work, starting over completely (rarely requires Windows restart) is the ultimate fixer.
- And if nothing is still working, you may need to check the "Fuse" settings in the Device Programming window.
