I am currently working on burning my CCS program on to flash. According to Mr. Rulph Chassaing, this is done in the regular sequence( i.e. by adding libraries,asm files, C files,linker file, and the header files).He then says that we need to replace the asm file and the command linker file with the files <vecs_int_flash.asm> and <c6713dsk_flash.cmd> respectively, after which we are to build the project. It is at this point that i get the following error in CCS:--------------> [Linking...] "C:\CCStudio_v3.1\C6000\cgtools\bin\cl6x" -@"Debug.lkf" <Linking> undefined first referenced symbol in file --------- ---------------- _c_int11 E:\Matlab2006b\work\Distortion_c6000_rtw\obj\vecs_int_flash.obj>> error: symbol referencing errors - 'Distortion.out' not built>> Compilation failureBuild Complete, 2 Errors, 6 Warnings, 0 Remarks.\ If anyone knows what i can do about this eror and this _c_int11 variable, Pleeeeaaase help!! Any suggestions will be greatly appreciated!!!!!

In the second edition I've attempted to expand the explanation of how to put a program into flash memory. However, I think your problem is at an earlier stage - not specifically concerned with programming flash memory. You're encountering a problem compiling and linking the program that you intend to write to flash memory. _c_int11 is the name used throughout the book for an interrupt service routine function associated with interrupt INT11 and the codec via McBSP. It is 'hooked up' to INT11 in the vecs_int_flash.asm file. vecs_int_flash.asm essentially contains an interrupt vector table (here _c_int11 is given as the vector for INT11) and a short boot function. The function c_int11() should be defined in one of your source files. In the example given in the book it is defined in flash_sine.c. Are you trying the example as described in the book or have you written a different example in which you have not defined the function c_int11()? Hope this helps. Donald
