FRDM-K64F Open-SDA failure

[MAPC]

Hello,

I'm running into a strange situation. Suddenly, I lost FRDM-K64F Open-SDA connection. I followed several posts in this Community, but nothing works. The only thing I didn't try yet was reprogramming K20 with the Open-SDA .srec file, because I don't have a Universal Programmer like U-Multilink or a Segger J-Link.

I don't know what to do anymore.

Regards,

Marco Coelho

Hi Marco,

According to your statement, I think the issue mainly form the software of the OpenSDA interface broken.

And it need to reprogram the K20 to fix this issue, so please refer to this thread as follow for details.

OpenSDAv2

Have a great day,

Thank you very much, Jeremyzhou!

Thanks to your tips, I could bring my FRDM-K64F back to life and now I can program and debug through MBED GDB OpenOCD Debugger.7
