  1. NanoPi Neo2 - i2cdetect -l reports i2c-0 but i2cdetect -y 0 doesn't detect any devices (a single PCF8574A at 0x38)

    As per the Subject, the I2C bus 0 is enabled and detected, but I don't see an addresses being returned when I try the i2cdetect -y 0 command. I have a single PCF 8574A connected with address 0x38. and have double checked the wiring. The PCF8574A did respond on the I2C bus on another SBC. Thanks John
