ROM-6881 has two I2C-PIN-Header channels.
- I2C1对应底板SOM-DB2510的CN7
- I2C2对应底板SOM-DB2510的CN8(Note:需要在ROM-EG70上增加一个Jumper(I2C_Addr_Slt1的PIN1-2短接))
I2C Num | BUS Num | address |
I2C1 | 5 | 0X51 |
I2C2 | 8 | 0X51 |
Using ROM-EG70 Test Board to read I2C flash. Using I2C1 as an example:
# /tools/test/adv/i2c/iic_pin_test.sh 5 0x51
Using ROM-EG70 Test Board to read I2C flash. Using I2C2 as an example:
# /tools/test/adv/i2c/iic_pin_test.sh 8 0x51
