sir,
i have included gpio header file csl_gpio5502.h
in that a structure has been explained as follows :

typedef struct {
#if (_GPIO_PARALLEL_SUPPORT)
     Uint16 ioen;
#endif
     Uint16 iodir;
} GPIO_Config;
 
for that structure i have created an object and called in my program as below
GPIO_Config pincfg;

 void GPIO_init()
  {
   pincfg.iodir=0x00FF;   // all the GPIO pins as  output pins
  }            
  
void main()
{
 CSL_init();
GPIO_init();
}
 
wts wrong with this code  kindly explain me abut that IOPORT keyword

  Hi Shanthi,
   
  Regarding you GPIO problem, are you using IOPORT key word?
  All MMR registers are in IO memory.
  To access any MMR registers, you must have to use IOPORT key word. Otherwise it will write on
location of data memory rather then in I/O memory.
   
  About command file, you have to only create one file with extension *.cmd and add it in your
project. The syntax of command file can be found from TI's documents.
   
  Hope this will help you.

    sir,

    i am using the TMS320VC5502 processor & i am using CCSV3.1......the problem is about hw
to create command file & wt r all the files i have to include with the source file besides
the header files.........and another one problem while debugging my code suppose for example
    if i have initialized a register say (GPIO reg) IODIR=0x00FF;in my program
    while debugging the data is getting updated but the memory address is incorrect.actual
address of that reg is 0x3400 but the data get updated in location0x240A.........so i need a
clear idea about the cmd file.........so can u help me abut hw to create or modify cmd
file....
