Hi,
Im trying to use an interrupt on MCA-gpio 1 (configured as active high) to wake up my Connectcore 6UL SBC pro from standby. The interrupt pulls the line low.
I run:
gpiomon --num-events=1 --falling-edge mca-gpio 1 &
standby
The problem is, when standby is run, the MCA gpio pins voltage drops to ~0.8V, triggering its own interrupt and waking it up near instantly. If I run standby without setting the interrupt, the voltage drops too.
Am I missing something to configure the MCA to maintain its voltage regulation etc?
