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. b
adding
libraries,asm files, C files,linker file, and the header files).He the
says that
we need to replace the asm file and the command linker file with th
files
<vecs_int_flash.asm> and <c6713dsk_flash.cmd> respectively, after whic

we are to build the project. It is at this point that i get the followin
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 failure

Build 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!!!!!

Hello Ameesh,

Are you using the first or the second edition of the book? 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.
