Description[edit | edit source]

i.MX6 can handle external pins in many different ways and most of them can be configured as GPIOs. When a pin is set as a GPIO, it is possible to read its value, change its direction or change output value directly from the shell.

Signals[edit | edit source]

The following table describes some GPIOs signals available on J33:

Pin# SOM Pin# Pin name Pin function Pin Notes
28 J10.191 EIM_D26 GPIO3_IO26
30 J10.193 EIM_D27 GPIO3_IO27
32 J10.50 GPIO_17 GPIO7_IO12
34 J10.40 GPIO_6/I2C3_SDA GPIO1_IO06

Device mapping[edit | edit source]

GPIOs can be used directly on Linux kernel device driver or can be configured on the device tree.

Device usage[edit | edit source]

See the GPIOs page on the DESK-MX6-L Software Manual.
