Piasiv1206 5:0801179037cd 12 Use pull up resistors
Piasiv1206 5:0801179037cd 13 Test Sample I2C with Tiva
Piasiv1206 5:0801179037cd 14 Learn about the I2C in freescale boards
Piasiv1206 5:0801179037cd 15 Check I2CReceiveData and I2CSendData compatibitily with Tiva
Piasiv1206 5:0801179037cd 16 Now Use ROM boot loader
Piasiv1206 5:0801179037cd 17 if it works get the flash code from CDMS people and try with that
