Brand-new FRDM-K64F board not working

I just got a FRDM-K64F board.

I closely followed the Getting Started Guide (Get Started with the FRDM-K64F | NXP ).

I connected the PC to the debug adapter USB port. The device should have come flashed with a demo that should flash the RGB LED according to readings from the on-board accelerometer, but nothing happened.

Next I installed the development tools, and, again following the guide, tried the Hello World example. The example compiled fine, and the IDE could talk to the on-board debug adapter, but it failed to communicate with the target chip. The messages from the debugger can be found below.

I am on Windows 10. I am using the latest version of the SDK and MCUXpresso toolchain and IDE.

Please advise.

Many thanks & best regards

Pol

I have found a solution.

The MCU stuck in reset was something I could look for with Google. Turns out it is a common problem. Even though the board is new (date codes suggest manufacturing no earlier than mid 2018) it apparantly came with an old version of the OpenSDA bootloader and firmware.

For any future reader: follow the instructions here OpenSDA Serial and Debug Adapter | NXP  and here DAPLink bootloader update | Mbed .

I can now program the device via the IDE just fine.

I noticed that the red LED D1 is dimly lit as soon as I power the board. (It lights up much brighter when I push the Reset button.) Per the schematics, I gather this means the K64 is held in reset.

EDIT: Just measured it, the RST pin of the K64 sits at 1.6V.

I guess my board is faulty?

Hi Pol,

 

Please try to execute a mass erase by doing the following.

Hi Felipe,

Thanks for the hint.

It's still failing with a similar error.

Best,
