CCS/CC2650MODA: Adding I2C driver to "simple_peripheral" cc2650stk for CC2650MODA

Part Number: CC2650MODA
Other Parts Discussed in Thread: CC2650STK

Tool/software: Code Composer Studio

Hello all,

I am trying to add I2C driver in simple_peripheral project for CC2650MODA.

1. Firstly I have made changes in board files for simple_peripheral, compiled - build - debug, SUCCESS (able to discover CC2650MOD on mobile app).

2. Then I added I2C driver folder in "Driver " section, Sensor folder in Middleware, added required header files " .h ", solved all compile queries,  compiled - build - debug, Success (able to discover CC2650MOD Aon mobile app).

3. Then I added SensorI2C_open() in SimpleBLEPeripheral_init, compiled - build - debug, UnSuccess (Not able to discover CC2650MODA on mobile app).

4. To solve this I commented line " // i2cHandle = I2C_open(Board_I2C, &i2cParams);"  from SensorI2C_open function,  compiled - build - debug, Success (able to discover CC2650MODAon mobile app).

So, problem is in file "I2C_Handle.c" - function "I2C_open(unsigned int index, I2C_Params *params)" on line

return (handle->fxnTablePtr->openFxn(handle, params));

When I press Ctrl+Left_Mouse_Button, (Expected is to open definition of function) , instead it gives error as

"An internal error occurred during: "Open Declaration.
java.lang.NullPointerException" Please find attached image and board files for reference."

I this application is getting crashed over here...

Can anyone help in solving this?
