=== 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

===Requirements===

* ROCK CM3 IO
* USB 3.0 or 2.0 male type A to male type A cable
* Host PC running Linux OS

===Software preparation===

* Kernel version

USB gadget driver must be enabled to configure usb net. You need to update the kernel to at least version 4.4.143-46-rockchip.

* Stop conflicting services

So far, Type-C OTG port only supports one Gadget function. To use use USB net, here need to stop rockchip-adbd service.

<pre>
root@radxa-cm3-io:~# systemctl stop rockchip-adbd
root@radxa-cm3-io:~# systemctl disable rockchip-adbd
root@radxa-cm3-io:~# reboot
</pre>

===Load kernel module===

* Connect the ROCK CM3 IO to PC with a USB to USB A cable.
* Install kernel module on ROCK CM3 IO

<pre>

===Requirements===

* ROCK CM3 IO
* USB 3.0 or 2.0 male type A to male type A cable
* Host PC running Linux OS

===Software preparation===

* Kernel version

USB gadget driver must be enabled to configure usb net. You need to update the kernel to at least version 4.4.143-46-rockchip.

* Stop conflicting services

So far, Type-C OTG port only supports one Gadget function. To use use USB net, here need to stop rockchip-adbd service.

<pre>
root@radxa-cm3-io:~# systemctl stop rockchip-adbd
root@radxa-cm3-io:~# systemctl disable rockchip-adbd
root@radxa-cm3-io:~# reboot
</pre>

===Load kernel module===

* Connect the ROCK CM3 IO to PC with a USB to USB A cable.
* Install kernel module on ROCK CM3 IO

===Remind===

If you can't ping the PC or rock pi.You should check your gateway.

Here's how to check for hardware problems.If it is successful, then the hardware is ok.

In Rock CM3 IO

<pre>
root@radxa-cm3-io:~# route add -net 10.0.1.0/24 gw 10.0.1.1 dev usb0
root@radxa-cm3-io:~# iperf3 -s
</pre>

In PC

<pre>
radxa@x86_64_pc:~$ radxa@x86_64_pc:~$ route add -net 10.0.1.0/24 gw 10.0.1.2 dev usb0

=== 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
