FRDM-KL25Z project link error Undefined symbol Driver_I2C0

Bruce Graham

I created a project for my FRDM-KL25Z board.
In "Manage Run-Time Environment", I added I2C using CMSIS Driver | I2C | Multi-Slave.
My app code includes "Driver_I2C.h".
My code compiles, but I get a linker error:

Error: L6218E: Undefined symbol Driver_I2C0 (referred from i2c_multislave.o).

See details below.

I guess Driver_I2C0 is declared in a library that is missing from my project.

Can somebody point me to some uVision docs that would help me correct the problem?

Thanks,
Bruce Graham

    I know how to add I2C support in other IDE projects. I just don't know how to do this in Keil.

    Since I added I2C to my project using the "Manage Run-Time Environment" dialog, I am assuming that this would have added the required I2C library to my project.

    Since the error indicates that the linker is looking for an object named "Driver_I2C0", I am guessing that a library, or some Keil provided source code, needs to be added to my project.

    What additional steps do I need to do to add I2C to my project?

    Thanks,
    Bruce
