Loss of data during communication over I2C protocol

Question asked by Pavan Gidaveer on Jan 11, 2017



We have configured MPC5200B as a slave for I2C communication, where master is Cypress's EZ-USB.

When in slave transmit mode, multiple data bytes (14 bytes) are written in I2C Data I/O Register (MBAR + 0x3D10/0x3D50) back to back for transmitting to Master.

But on Master side some of these data bytes does not get received and this loss of data doesn't follow any proper sequence.


Could you please suggest us possible reasons which will be causing this loss of data?
