Project: Make the bl602 into a advanced TTL adapter

This is my first project idea. Creating a page for it.

In case it's helpful, a very similar idea to this has already been productized. https://www.cnx-software.com/2021/06/21/rv-debugger-plus-uart-jtag-debug-board-bl702-zigbee-ble-risc-v-soc/ https://github.com/pine64/bl602-docs/pull/38

The product kind of pivots around the JTAG signaling, but there's another half of the device that provides enough serial TTL to be used at moderate speeds. The hardware has an undeniable resemblance to Pine Nut: https://www.pine64.org/pinenut/, which trades the second serial for Wifi.

Combining the USB-C with 2 serial ports and a capable RISC-V engine between them opens lots of possibilities for MITM, filtering, conversion, capture, logging and more. The SDK is already there. I think a lot can be done with this idea.

Good luck with your project.
