Trouble Accessing Pi's RX and TX With Serial1


#21

Not yet. I’d like to find some time soon to improve the Pi firmware and add compatibility for the Pi Zero W and Pi 1. Stay tuned for updates.


#22

Any progress ?

It’s been 6 months since last post here and firmware documentation still mention that Serial1 is incomplete…

I tried the workaround with WiringPI include, but it doesn’t compile.
Processing test.ino
Found unsafe content Found: #include "/
make -C …/newlib_nano
make[1]: Entering directory '/firmware/newlib_nano’
make[1]: Nothing to be done for ‘all’.
make[1]: Leaving directory '/firmware/newlib_nano’
make -C …/user
make[1]: Entering directory '/firmware/user’
make[1]: Leaving directory '/firmware/user’

Maybe this can help for raspberry pi 3.

I have a raspberry pi 2 and I would like to be able to use the UART.

ttyAMA0 is working in minicom, but Serial1 doesn’t seem to work in particle agent.
