Our firmware experiences failed CRC checks occasionally. Using scope and logic analyzer, we tracked down to the I2C2 device issuing a NAK when firmware sent a "Continue" command. Does not occur on any other I2C port. What may be causing this problem?
Using LPCopen library. Using I2C1, 2, & 3 as SMBus running at 100KHz.
