 C:\VisSim80\cg>lnk2000 -c -x -q -mWheelchairControl.map WheelchairControl.obj -l lib\ii_F280x_fpusr.lib  -heap 414 -stack 414  -o WheelchairControl.out lib\F28062''lnk.cmd  'lib\F28062lnk.cmd', line 110: error: placement fails for object '.cinit', size 0x32b (page 0).

This link error says that you don't have enough RAM on the chip to hold your entire program. Your look-up table data becomes a constant initializer for an array, and can take a lot of RAM if you have a big table. You must check the 'Target Flash' option before compiling, then your code and initial data will be allocated to flash. There is a lot more flash than RAM on the chip, and this will free up RAM to only hold your stack, heap and variables.
After you compile for flash, you must burn your program to flash before running VisSim in debug mode. You can burn the .out file to flash using either Code Composer or TI's new Uniflash tool

Hi Anders:

I tried Flashing .out file generated. i get this error in CCSV4: C28xx: GEL: Warning loading file 'C:\Program Files (x86)\Texas Instruments1\ccsv4\emulation\gel\F2806.gel', line 102: the function 'GEL_OpenWindow' is not supported.
