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
