Hi, Are you aware of pin-muxing subject?
You can change GPIO settings in U-boot with gpio_* functions. You can change them in DTS with gpio-edm driver from Wandboard kernel ( https://github.com/wandboard-org/linux/blob/4.1-2.0.x-imx/drivers/input/keyboard/gpio_edm.c ) You can also change them in running Linux environment, i found this resource quite complete http://www.variwiki.com/index.php?title=DART-6UL_GPIO Best Regards, Vincent 2018-01-13 5:55 GMT+01:00 Mathew K Tharakan < [email protected]>: > Hi, > > I'm using iMX6ULL evk.
