GPIO Table - Bullet64 - 06-26-2021 I have edit the wiki with table for GPIO https://wiki.pine64.org/wiki/Quartz64#GPIO_Pins Can someone please check it? Thanks. Source: https://wiki.pine64.org/images/3/31/Quartz64_model-A_schematic_v1.0_20201215.pdf RE: GPIO Table - CounterPillow - 06-29-2021 According to pgwipeout, pin 7 right now is likely to just be a regular GPIO (GPIO0_A0), as he has been unable to actually get CPU_REFCLK_OUT from there. You can try this hypothesis by wiring an LED through a 220 Ohm resistor between it and GND, and then runningĀ gpioset 0 0=1 but this probably all depends on your device tree and kernel you're running. Some more notes on the GPIOs I've written up based on the schematics a while ago:
I might add those as notes to the wiki table later when I get the time. It's also important to note that these are the GPIO bus assignments for the Model A. But we can do the wiki formatting distinction when the Model B ever sees the light of day. |
