K64F I2C driver Ignore NAK when sending 1 byte

unknowncoder — Thu, 07 Jun 2018 19:19:07 GMT

I think I may have found a bug in the in the K64F i2c driver, specifically fsl_i2c_edma.c.

When the I2C_MasterTransferEDMA() is called to only send 1 byte it doesn't check for NAK after it sends. Is this a bug or was this done for a reason.

I've add the call result = I2C_CheckAndClearError(base, base->S); after while (!(base->S & kI2C_IntPendingFlag));

According to I2C bus specification, for the last byte, I2C don't care the NAK
