Re: Soft serial 9k6 for debugging on free GPIO?

Hi Martinj,

This Zephyr example does UART over GPIO:

Here's a picture with the system overview:

However it receives the data to send via RPMsg from a second core running Linux and vice versa.
It could be possible to remove the RPMsg related part and rewrite the code into a driver and select that peripheral as a debug console in board's DTS file.
The code requires a hardware timer and supports just 8N1 format.

Best regards,
