What does No Cortex-M Device found in JTAG chain mean?

Doug HIlton

When I try to execute the Blinky program

On menu, select Debug -> Start/Stop Debug Session

I get a dialog box:

JLink - Cortex-M Error

No Cortex-M Device found in JTAG chain.

Please check the JTAG cable and the connected devices.

The LPC-Link2 board is connected to the LPC4330-Xplorer board correctly.

Blinky compiles with no errors.

What should I look for?

    Hello Christopher,

    After speding some time in other aspects from my project, I´m returning to the J-LINK issue.

    I´m still stuck on that. Can you help me explaining how to re-flash the J-LINK FW?

    I already downloaded in my desktop the JLink_OpenSDA_V2_2015-04-23.bin, indicated for my Freescale FRDM-K64F.

    Many thanks in advance and Congrats!!! for the great Support for the community since the beginning.

    Chees,
