How to use NX emmc module i2c1

How can to use i2c1(189, 191ping)? I can’t measure i2c1_scl and i2c1_sda signal when i exec i2cdetect -y 1.
kernel.log (58.8 KB)

Try i2cdetect -y 8

Hi,
You are right, exec i2cdetect -y 8. It can measure i2c1_scl and i2c1_sda signal. Can you send the other i2c correspondence? Thanks.

Another i2c0_xx is map to i2c bus 1
