Hi,
I ordered two of these boards. I used JLinkExe to download code to them and to debug programs on them.
JLinkExe no longer works with either board. I get the same error from both boards when trying to connect to them. Here are the messages that I get from JLinkExe:

Did anyone else have these problems? Any ideas of how to fix this?
Thanks for any help
