I’m completely lost in the domain of Pinout Management of the Jetson Nano.
There is the Jetson Nano Datasheet here: Jetson Nano Datasheet
Page 39 summarizes the complete Pinout.
My Example:
- SPI1_CS0 is on Pin 110 and
- SPI1_CS1 is on Pin 112
I wanted to use these two ports for switching a LED (output) on off with a trigger (input).
When I printout the gpio definition: sudo cat /sys/kernel/debug/gpio
I find these two ports as
gpio-15 (SPI1_CS0 )
gpio-232 (SPI1_CS1 )
But this number gpio-15 and gpio-232 have nothing in common with the Pinout of the Jetson Nano Datasheet? How are they related? How do I know which Nano-IO port corresponds to which gpio?
with the help of the image below, i was able to determine that SPI2-CS0 & SPI2-CS1 (Names changed??) corresponds to Linux gpio-15 → BCM 24 and gpio-232 → BCM 23.
But I’m lost to do this for all the other ports. Could you please shed some light on this topic?
