hello @Tolga, please refer to the setting below. It’s not necessary to use uart1, uart2 or uart4 can be used, too. Using uart3 however is not suggested, since it’s used for uart log output https://github.com/TinkerBoard/TinkerBoard/wiki/User-Guide#gpio-config-table-for-tinker-board-and-tinker-board-s First, modify the /boot/config.txt file as follows, and then reboot to enable I2C1 and I2C4. ##### Hardware Interface Config ####### Note: fiq_debugger and uart3 use the same pin. Set fiq_debugger first while bb oth on. ## ## Note: uart4 and spi0 are the same pins. Set the latter one while both on. ## ## Note: uart2 is the same pins to pwm2 and pwm3. Set the latter one while both on. ## intf:fiq_debugger=on intf:i2c1=on intf:i2c4=on #intf:spi0=off #intf:spi2=off #intf:pwm2=off #intf:pwm3=off intf:pcm_i2s=on intf:uart1=on #intf:uart2=off #intf:uart3=off #intf:uart4=off Chip,line Device Path GPIO number Function2 Function1 GPIO Pin# Pin# GPIO Function1 Function2 GPIO number Device Path Chip,line --- --- --- --- VCC3.3V_IO --- 1 2 --- VCC5V_SYS --- --- --- --- 8,4 GPIO:/sys/class/gpio/gpio252 I2C:/dev/i2c-1 252 --- I2C1_SDA GPIO8_A4 3 4 --- VCC5V_SYS --- --- --- --- 8,5 GPIO:/sys/class/gpio/gpio253 I2C:/dev/i2c-1 253 --- I2C1_SCL GPIO8_A5 5 6 --- GND --- --- --- --- 0,17 GPIO:/sys/class/gpio/gpio17 17 --- TEST_CLKOUT GPIO0_C1 7 8 GPIO5_B1 UART1_TXD --- 161 GPIO:/sys/class/gpio/gpio161 UART:/dev/ttyS1 5,9 --- --- --- --- GND --- 9 10 GPIO5_B0 UART1_RXD --- 160 GPIO:/sys/class/gpio/gpio160 UART:/dev/ttyS1 5,8 5,12 GPIO:/sys/class/gpio/gpio164 SPI:/dev/spidev0 UART:/dev/ttyS4 164 UART4_CTSN SPI0_CLK GPIO5_B4 11 12 GPIO6_A0 I2S_SCLK --- 184 GPIO:/sys/class/gpio/gpio184 6,0 5,14 GPIO:/sys/class/gpio/gpio166 SPI:/dev/spidev0 UART:/dev/ttyS4 166 UART4_TXD SPI0_TXD GPIO5_B6 13 14 --- GND --- --- --- --- 5,15 GPIO:/sys/class/gpio/gpio167 SPI:/dev/spidev0 UART:/dev/ttyS4 167 UART4_RXD SPI0_RXD GPIO5_B7 15 16 GPIO5_B2 UART1_CTSN --- 162 GPIO:/sys/class/gpio/gpio162 UART:/dev/ttyS1 5,10 --- --- --- --- VCC3.3V_IO --- 17 18 GPIO5_B3 UART1_RTSN --- 163 GPIO:/sys/class/gpio/gpio163 UART:/dev/ttyS1 5,11 8,9 GPIO:/sys/class/gpio/gpio257 SPI:/dev/spidev2 257 --- SPI2_TXD GPIO8_B1 19 20 --- GND --- --- --- --- 8,8 GPIO:/sys/class/gpio/gpio256 SPI:/dev/spidev2 256 --- SPI2_RXD GPIO8_B0 21 22 GPIO5_C3 --- --- 171 GPIO:/sys/class/gpio/gpio171 5,19 8,6 GPIO:/sys/class/gpio/gpio254 SPI:/dev/spidev2 254 --- SPI2_CLK GPIO8_A6 23 24 GPIO8_A7 SPI2_CSN0 --- 255 GPIO:/sys/class/gpio/gpio255 SPI:/dev/spidev2.0 8,7 --- --- --- --- GND --- 25 26 GPIO8_A3 SPI2_CSN1 --- 251 GPIO:/sys/class/gpio/gpio251 SPI:/dev/spidev2.1 8,3 7,17 GPIO:/sys/class/gpio/gpio233 I2C:/dev/i2c-4 233 --- I2C4_SDA GPIO7_C1 27 28 GPIO7_C2 I2C4_SCL --- 234 GPIO:/sys/class/gpio/gpio234 I2C:/dev/i2c-4 7,18 5,13 GPIO:/sys/class/gpio/gpio165 SPI:/dev/spidev0.0 165 UART4_RTSN SPI0_CSN0 GPIO5_B5 29 30 --- GND --- --- --- --- 5,16 GPIO:/sys/class/gpio/gpio168 SPI:/dev/spidev0.1 168 --- SPI0_CSN1 GPIO5_C0 31 32 GPIO7_C7 UART2_TXD PWM 239 GPIO:/sys/class/gpio/gpio239 UART:/dev/ttyS2 PWM:/sys/class/pwm/pwmchip3 7,23 7,22 GPIO:/sys/class/gpio/gpio238 UART:/dev/ttyS2 PWM:/sys/class/pwm/pwmchip2 238 PWM2 UART2_RXD GPIO7_C6 33 34 --- GND --- --- --- --- 6,1 GPIO:/sys/class/gpio/gpio185 185 --- I2S_LRCKRX GPIO6_A1 35 36 I2S_LRCKRX UART3_RXD --- 233 GPIO:/sys/class/gpio/gpio223 UART:/dev/ttyS3 7,7 7,8 GPIO:/sys/class/gpio/gpio224 UART:/dev/ttyS3 224 --- UART3_TXD GPIO7_B0 37 38 GPIO6_A3 I2S_SDI --- 187 GPIO:/sys/class/gpio/gpio187 6,3 --- --- --- --- GND --- 39 40 GPIO6_A4 I2S_SDO0 --- 188 GPIO:/sys/class/gpio/gpio188 6,4
