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....
