on Apache RTOS might become a Feature Phone ... But first let's learn about its USB Controller

's USB Controller works like the Mentor Graphics USB Controller ... Except the USB Registers are scrambled (like eggs)

@lupyuen Spoke with meshtastic guys at discord - they said that i2c bridge is an issue. Don't know why? I'd like to get my pinephone & lora back cover in use soonest!

@exfil Yep wonder why the I2C Bridge would be a problem, since JF's driver works perfectly fine 🤔

@lupyuen I need to study this. I have LORA cover and Pinephone. My messaging application would benefit hugely if this turns possible.

@exfil I might just port Meshtastic to PinePhone on NuttX ... And prove them wrong 😂

@lupyuen Like that. I need to study that NuttX as well. What is your main motivation of using Nuttx ?

@exfil I think it might be a good educational exercise to document and explain how we build a LoRa Communicator with a real-time OS like NuttX?

Also I have a hunch that a real-time OS might work better for low-level hardware like LoRa Transceivers.

Meshtastic was designed for Arduino, so it would probably be simpler to run on an RTOS.
