Unlocking the AMW004 JTAG Interface

The Zentri AMW004 module requires a special procedure to prepare it for use with the ZentriOS SDK. This applies to any board with an AMW004 module.

The procedure unlocks the JTAG Interface and erases the flash.

AUX and RESET refer to buttons on the Piranha board.

  1. Plug Piranha into the PC, but disconnected from the Mackerel board.

  2. Hold down the AUX button.

  3. Plug the Piranha cable into the Mackerel board.

  4. While still holding the AUX button, press and release RESET.

  5. Release the AUX button.

  6. Press and release RESET.

You can now run the ZentriOS Setup Device Wizard.
