Hello,
There is 2 UART on GPIOs one(18,19) for Linux logs, and one(pin 15,16) is mux with SPI, I need SPI and now there is no UART left for general propose, Now to access other GPIOs as UART, I found some drivers but thats for Raspb Pi kernel and its a bit difficult for me to bring up.
As per I know, there is no UART in M.2. slot as well. So only thing left is to bring software UART on GPIOs, Can someone guide me for the right drivers, or if there is what changes I should make.
I am trying this one
Please let me know if someone have done this already.
Thank you.
