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

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,

    I´m still having an issue with my freescale and I´m not able to upload the code from apnt_271 sample, to continue my project.

    I still cannot read the JLINK version number, from the JTAG Device Chain panel, in the Debug tab from Debug Settings.

    Please, any link or direction to guide me in the re-flash process?

    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.

    Cheers,

    Waldemir.
