Linux/AM3358: I2C timing issue

Dileep D R
Intellectual 620 points
Part Number: AM3358


Tool/software: Linux

Hi,

When I configure I2C clock frequency to 100KHz, on oscilloscope it measures 104KHz with almost 50% duty cycle.

But when I configure for 400KHz it shows 460KHz on oscilloscope, duty cycle will not be 50%. TON will be 30%.

I am only setting clock frequency in device tree file. Please let me know whether i am missing any configuration.

Regards,

Dileep
