Hi,

I am working with TC399x AURIX MCU.

I2C Channel 1 is configured in Standard Mode and acting as Master.

I am using Asynchronous mode to read and write.

here are the steps,

1.  AsyncWrite with device address (Data Transfer and Protocol Interrupt is hit) and the controller is changed to read mode

2. AsyncRead with device address (Data Transfer interrupt hit) and But the controller doesn't seem to acknowledge the received data. because of this, the MCU protocol interrupt is not hit.

The above is observed only during debugging with breakpoints.

however, if I don't set breakpoint, there is no issue as AsyncWrite and AsyncRead is working fine.

Could you please help me with this?

Thanks and Regards,

Hi,

Since the driver works as expected without the influence of the debugger, I do not see any issue here.

Could you confirm if you are using an ILLD- or MCAL-based driver?

Best Regards.
