I'm using some code (https://review.coreboot.org/c/coreboot/+/35523/55/src/mainboard/acer/aspire_...) to set the GPIO pins.
can you elaborate on that. How did you figure out the GPIO pins? why are you using this system76 sequence?
the dGPU should show up on the PCI bus
Although the GPIO settings work,
How did you confirm that?
the PCI device does not appear.
Hmmm, looking at the code, it doesn't seem to leave much time. IIRC, a PCI device should be given 100ms (or was it 200ms?) to show up.
Neither I2C controller appears either (15.0 and 15.1).
That is really odd, now I'm a little bit concerned about the well- being of your board.
