General purpose input-output (GPIO) connector

ROCK 5B has one 40-pin expansion header. Each pin is distinguished by color.

GPIO number

Rockchip RK3588 GPIO has 5 banks, GPIO0 to GPIO4, each bank has 32 pins, naming as below:

GPIO0_A0 ~ A7 
GPIO0_B0 ~ B7
GPIO0_C0 ~ C7
GPIO0_D0 ~ D7
   
GPIO1_A0 ~ A7
....
GPIO1_D0 ~ D7
GPIO2_A0 ~ A7
....
GPIO2_D0 ~ D7
GPIO3_A0 ~ A7
....
GPIO3_D0 ~ D7
GPIO4_A0 ~ A7
....
GPIO4_D0 ~ D7


For Rockchip 5.10 kernel, the GPIO number can be calculated as below, take GPIO4_D5 as an example:

GPIO4_D5 = 32*4 + 8*3 + 5 = 157
(A=0, B=1, C=2, D=3)

To set GPIO4_D5 output

# cd /sys/class/gpio
# echo 157 > export
# cd gpio157
# echo out > direction
# echo 1 > value     # output high
# echo 0 > value     # output low
