TMDSCNCD28335: I have error after execution of program.

The warnings are because you have not defined these sections in your linker command file.  They are not errors - your program will still build and run, but these sections may not be where you expect them because the linker will place them where it can in program memory.  You should have lines in your linker command file so the linker knows what to do with these sections.  For example:

ramfuncs : > L0SARAM, PAGE = 0
dclfuncs : > L0SARAM, PAGE = 0

There are examples of coefficient initialization in the DCL (make sure you have the latest DCL release In C2000Ware).  The simplest way is to write directly to the coefficients in the controller structure in your main program.  There is a DF22 example of this in the /examples sub-directory which shows how you can initialize the coefficients.  The DF23 controller is similar but with another two variables:

DCL_DF22 controller1 = DF22_DEFAULTS;

main()

{

// initialise full controller
controller1.a1 = -1.9417f;
controller1.a2 = 0.9417f;
controller1.b0 = 9.8549f;
controller1.b1 = -19.4165f;
controller1.b2 = 9.5636f;

...

Of course your coefficients would be different.
