I am using the fsl_i2c driver in my FreeRTOS task application to communicate with external host processer using the MK82FN256 as I2C Slave device @400kHz and running into some missed packets. Do I need to calibrate the I2C, if so, how?
You could verify the initialization with the examples of the K82's SDK and you can find all the information of the I2C module on chapter 58 on the reference manual.
