I find I2C0xx and I2C1xx on 40-Pin Expansion Header in NVIDIA Jetson Xavier NX Developer Kit Carrier Board P3509_A01.p579520-Jetson_Xavier_NX_DevKit_Carrier_Board_Specification_v1.0.pdf (1.3 MB)
If I want to use an audio codec which I2C is recommended?
How to confirm I2C’s address？
By the way, I find it dosen’t match with the Jetson Expansion Header Tool
I also find that there are several I2C bus:
user@Jetson-xavier-NX:~$ i2cdetect -l i2c-3 i2c 3190000.i2c I2C adapter i2c-1 i2c c240000.i2c I2C adapter i2c-8 i2c 31e0000.i2c I2C adapter i2c-6 i2c 31c0000.i2c I2C adapter i2c-4 i2c Tegra BPMP I2C adapter I2C adapter i2c-2 i2c 3180000.i2c I2C adapter i2c-0 i2c 3160000.i2c I2C adapter i2c-9 i2c i2c-2-mux (chan_id 0) I2C adapter i2c-10 i2c i2c-2-mux (chan_id 1) I2C adapter i2c-7 i2c c250000.i2c I2C adapter i2c-5 i2c 31b0000.i2c I2C adapter
So I guess i2c2 Pin shows above picture stands for i2c-2 with address 3180000?
What if I want to use i2c-8 or other i2c bus ?
Which spec can tell the way to configure i2c?
