Why RockPro64 I2C Port does NOT work?

[xwang2019]

I tried RockPro64 Images from 7.9 to 8.0 and not able to get I2C port to work. Does anyone have a successful experience using I2C port on RockPro64? Thanks.

Hi FrankM,

Thank you very much for your help. It is my mistake to use Pin #3 and Pin #5 (I2C_8) instead of Pin #27 and Pin #28 (I2C_4). Your instruction and example helped me to correct this mistake. I am now able to use I2C port on ROCKPro64 successfully. I am very appreciative for your help.

Regards,

Xiaoming

I am very happy if it works for you now. Have fun with your ROCKPro64

I think that it must work with pin #3 & #5 too. Will test it later this week.
