I2C bus CY_U3P_ERROR_LOST_ARBITRATION,
I use the I2C bus to write the image sensor device, but sometimes the returned message of CyU3PI2cTransmitBytes() is CY_U3P_ERROR_LOST_ARBITRATION. I have checked the I2C waveform with logic analyzer and the waveform looks good. I also checked the data of sensor register and it is correct.
Could anyone tell me what will cause this error ?
Thank you in advance.
