SWD with GPIO

TEMCEFF — Tue, 03 Mar 2020 05:08:14 GMT

Is there any one implemented Serial Wire Debugger with GPIOs?

(My idea is to implement SWD with GPIOs for Gang Programming purpose).

Regards,

Muralidhar.

Hi Muralidhar,

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
I'm not very clear with your question, whether you want to use the GPIOs to simulate the SWD to program target MCU.

Have a great day,
TIC

Hi jeremyzhou,

Yes, I want to use GPIOs to simulate SWD peripheral.

Hi Muralidhar,

Thanks for your clarification.
After a round of research, unfortunately:smileyplain:, there's no similar application note as you want.

Have a great day,
