I try to write I2C device driver on Android 11, I am a beginner.
Device_SCL <-> PIN_22 I2C_M3_SCL
Device_SDA <-> PIN_23 I2C_M3_SDA
Device_VDD <-> PIN_11 1.8V
Device_GND <-> PIN_24 GND
Device address is 0x45
First, use “VIM3_Pie_V210128” image
The device 0x45 was found correctly.
But, after build AOSP Android 11
The device 0x45 was not found, and device 0x30 was appeared oddly.
I use the I2C_AO(Pin 25&26), the device 0x45 can be found correctly.
What is wrong?
Should I modify some file?
