More details about 40-pin Header
- Pins marked with color orange are designed for debug console.
- PWM:x7,PWM0/PWM1/PWM2/PWM3/PWM6/PWM7/PWM11
- SPI:X2,SPI0/SPI3
- I2C:X2,I2C2/I2C4
- UART:X2,UART0/UART2
- ADC:X1, SARADC_IN3
- I2S:X2, I2S1/I2S2
IO Voltage
RK3566 have three IO voltages, 1.8V/3.3V. For CM4 IO, the high level voltage of GPIO pin on 40-PIN HEADER is 3.3V.
| GPIO | Voltage Level | Tolerance | | ---------- | ------------- | --------- | | SARADC_IN3 | 1.8V | 1.98V |
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
The GPIO number can be calculated as below, take GPIO4_D1 (PIN26 on 4-0PIN HEADER) as an example:
GPIO4_D1 = 4*32 + 3*8 + 1 = 153 (A=0, B=1, C=2, D=3)
To set GPIO4_D1 output
cd /sys/class/gpio echo 153 > export cd gpio153 echo out > direction echo 1 > value # output high echo 0 > value # output low
System images and usage
Get your favorite system images from Radxa CM3 RPI CM4 IO Downloads.
And check the features of Ubuntu or Debian.
Flash images
Radxa CM3 RPI CM4 IO board supports two boot methods including booting from eMMC and booting from MicroSD. Select one of the following methods.
Troubleshooting
Check ROCK 3 FAQs first, if it doesn't help, start a new post on the forum https://forum.radxa.com/c/rock3.
