I2CDXR not getting cleared while Performing I2C Communication

B M Mohan

Hi,

I am using the F28335, I2C module for my I2C Communication. The unit works well. But some Times the data is not getting transmitted out of the I2CDXR of the I2C Module.

Because of this XRDY never gets set, and the whole communication is stalled.

The same code was fucntional from past one year. The issue re-appears on Power Reset, and as well on I2C reset using the IRS bit.

This is at critical level to my Project.

Any help is greatly appreciated.

Regards,

Mohan

Guys,

I found out the reason, the date is not sent out, as the Clock is not generated in the I2C Module.

Now I need to know, why the Clock is not generated.

Please some one provide me input, why the clock is not generated.

Thanks,

Mohan

Hello,

I have a very similar situation to yours with the I2C. Did you finally found what was the issue with the clock?

Thanks
