We recommend you to use [[gpiod]] and libmraa, which support accessing GPIO pins by 40-pin header number, instead of SoC defined GPIO number.

  • I2C_EE_M1 (/dev/i2c-1)
  • I2C_EE_M3 (/dev/i2c-3)

I2S device (1)

  • TDMB

PWM devices (4)

  • PWM_B (/sys/class/pwm/pwmchip6/pwm1)
  • PWM_C (/sys/class/pwm/pwmchip4/pwm0)
  • PWM_D (/sys/class/pwm/pwmchip4/pwm1)
  • PWM_F (/sys/class/pwm/pwmchip2/pwm1)

To use PWM_C and PWM_D together, please use meson-g12b-pwm-c-d-gpioz-1-2 overlay instead of individual overlays.

UART devices (3)

  • UART_AO_A (/dev/ttyAML0)
  • UART_AO_B (/dev/ttyAML6)
  • UART_EE_C (/dev/ttyAML7)

if you enable UART_AO_B only or only enable UART_EE_C, the UART device is /dev/ttyAML6, if you enable UART_AO_B and UART_EE_C at the same time, the device of UART_AO_B is /dev/ttyAML6, and UART_EE_C is /dev/ttyAML7

SPI device (1)

  • SPI_B (/dev/spidev0.0)

GPIO number

GPIO Chip
 GPIO Name
 Base Offset Formula
First GPIOAO_x 412 0-11 Base + Offset
First GPIOE_x 424 0-2 Base + Offset
Second GPIOZ_x 427 0-15 Base + Offset
Second GPIOH_x 443 0-8 Base + Offset
Second BOOT_x 452 0-15 Base + Offset
Second GPIOC_x 468 0-7 Base + Offset
Second GPIOA_x 476 0-15 Base + Offset
Second GPIOX_x 492 0-19 Base + Offset

Take GPIOX_10 as an example.

The base is 492 and the offset is 10. So the GPIOX_10's GPIO number is 492+10=502.

We recommend you to use gpiod and libmraa, which support accessing GPIO pins by 40-pin header number, instead of SoC defined GPIO number.
