Android 13 GPIO/Edge2 IO board

Edge2
1

I need to use the GPIO pins on the IO board, i have managed to get the GPIO folders to generate using the export commands but i cant change the value(they stay hi), Im testing the GPIO pins and i get nothing from them.

Do i need to enable all this in a custom android build? Anyway you could ship the images with everythign enabled? Or am i missign something?

Im tryign to use GPIO 111/112 to drive some LED’s.

Im going by the table on Edge2 IO

|111|SPI1_MOSI|11|
| — | — | — | — | — |
|112|SPI1_MISO|12|

If these wont work out of the box can you point me to what pins i can use?

If i understand i make these changes to this file, then once i can build Android13 i can use these pins to drive my led’s?
