I’ve installed the LIBMRAA on my Buster image on Rock Pi S. And I’m accessing it from Python 3. That works fine…thanks!
But It doesn’t appear that the Pullup/Pulldown is exposed as something I can control. I’ve tried setting pin.mode(mraa.MODE_PULLUP) and PULLDOWN and they don’t appear to do anything. An unconnected GPIO line reads the same with either setting.
Board: 256M, V13 with 1G NAND, NO BT/WIFI
I’m trying to use the GPIOs on the Header 2 connector, pins 39-46
Is this correct? Can’t control the internal pullup/down? Or am I missing something?
If the mode can’t be set, can you tell me if the internal pullups or pulldowns is enabled?
I believe, looking at the schematic for V13 that GPIO3_B2,3,4,5 are connected to the NAND flash. Is this right? Does this mean I should not use those GPIOs for other purposes?
