Hi

We have been performing some tests under Linux with the CY7C65215A running in i2c master mode.

When no receiver is present with the transmitted address or the receiving device is busy and unable to respond so a NACK occurs that the CY7C65215A appears to be holding the SCL line low until a USB timeout occurs.

 

Would you please advise how to overcome this issue?  We are running under Linux.

 

Thanks

 

Malcolm

Hi Malcolm,

Apologies for the delay in response.

Can you please probe both the SDA and SCL lines and share the traces?

Regards,

Mallika
