Call to qapi_I2CM_Open hangs

Hi,

The call to qapi_I2CM_Open() hangs and never returns.

Specifically, I'm calling:

int  res = qapi_I2CM_Open(QAPI_I2CM_INSTANCE_002_E, &client_handle);

 

What would cause this call to never return?

Thanks,

Tom

Kindly help to confirm the behaviour using QCLI_demo if I2C Open hangs.
The unexpected hang behaviour might be result of clock/platform/hardware resource not being enabled.
