I have been using a TWR-K60 board with my J-Link debugger for a couple years now with no issue at all, also use the same J-Link with various other boards and a variety of processors. I searched the forums here, tried the various things suggested to no avail. J32 removed, reflashed with latest binary. Still nothing. It's a rev A0 board according the the box. I am using IAR workbench, and when I try to load an application into the K65, I just get "Failed to get CPU status after 4 retries." Debug log shows "Could not measure total IR len. TDO is constant high."
