R9A02G021 jlinkexe error "Could not connect to the trget device"

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:

Connecting to target via cJTAG

Failed to identify target. Resetting via Reset pin and trying again.

****** Error: Timeout while waiting for core to halt after reset and halt request

Did anyone else have these problems? Any ideas of how to fix this?

Thanks for any help
