More details about 40-pin Header In V1.0

Pins marked with color orange are designed for debug console.

GPIO number

Rockchip RK3566 GPIO has 5 banks, GPIO0 to GPIO4, each bank has 32pins, naming as below:

GPIO0_A0 ~ A7 
GPIO0_B0 ~ B7
GPIO0_C0 ~ C7
GPIO0_D0 ~ D7
   
GPIO1_A0 ~ A7
....
GPIO1_D0 ~ D7

For Rockchip 4.19 kernel, the GPIO number can be calculated as below, take GPIO4_A7 (PIN26 on 40-PIN HEADER) as an example:

GPIO4_A7 = 4*32 + 0*8 + 7 = 135
(A=0, B=1, C=2, D=3)

To set GPIO4_A7 output

cd /sys/class/gpio
echo 135 > export
cd gpio135
echo out > direction
echo 1 > value     # output high
echo 0 > value     # output low

NOTE

GPIO0_D5 GPIO0_D6 GPIO2_C2 pin voltage is 1.8V
