I installed ubuntu server 18.04, and I am trying to run ros melodic on it. However, the magni is not booting up because the GPIO are not operating properly. are there specific packages I need?
Hi…the RPI4 has precisely the same GPIO pinout as the RPI3.
However, on the off chance that you need them, there are various new equipment fringe drivers that can be alloted to GPIO’s, relatively few individuals use them yet, so there isn’t a lot of information about them, however
Notwithstanding the heritage peripherals we have:
4 new PL011 UARTs with fair measured FIFOs
4 new I2C regulators with fixed (or diversely broken) clock extending
4 duplicates of the old SPI regulator

For my update to Noetic on Ubuntu 20.04 on both Pi 3 and Pi 4 I needed to do this to get the Ubiquity Magni nodes working - needed for the sonar board, Wifi LEDs and OLED.
