Dear all;
The prolem entangle me two weeks!
I am working on a C6713 based board , the host is C5402 and the DSP is C6713.
Connecting the C6713 to a Host processor C5402 and bootloader program are very
like to
"Implementing the C6xxx HPI Boot Process"(spra512).
if I load following program through HPI:
// timer1 set; The output wave can been seen in pin13 "pin_name = tout1".
#define CTL1 (unsigned int*) 0x01980000
#define PRD1 (unsigned int*) 0x01980004
#define CNT1 (unsigned int*) 0x01980008
main()
{
*CTL1= 0x311;
*PRD1=0xffff;
*CTL1= 0x3d1;
while(1);
}
the program runs fine.
But if i load following program through HPI:
// timer set program provided by 2003 Texas Instruments.
// in c:\CCStudio_v3.1\examples\dsk6713\csl\timer
void main() {
/* Initialize the chip support library, must when using CSL */
CSL_init();
/* Open TIMER1 device, and reset them to power-on default state */
hTimer1 = TIMER_open(TIMER_DEV1, TIMER_OPEN_RESET);
/* Configure the timer devices */
TIMER_configArgs(hTimer1,
TimerControl, /* use predefined control value */
0x00100000, /* set period */
0x00000000 /* start count value at zero */
);
/* Start the timers */
TIMER_start(hTimer1);
while(1); /* waiting for interrupt*/
}
Nothing happened !
if I connect the JTAG and then start above program from the JTAG to C6713 (in
Code Composer), all is good!
Why? Many thanks!
jiangyuzhong.
Please help me about C6713 HPI problem?

Before you try bootloading, you should run basic memory tests. You should write some
small C5402 code that:
1) Writes a pattern to location A (try 0x1000) in C6713 internal memory. For
example, write 0x100 locations with different values.
2) Writes another pattern to location B (try 0x2110).
3) Goes back and reads first pattern from location A -- is it correct?
Furthermore you should repeat the above tests using both auto-increment and
non-autoincrement HPI modes, and you should try many combinations of locations A and
B.
Can your C5402 code do this? If your C5402 EMIF interface can't do this, then it
can't do reliable bootload.

Dear jiangyuzhong,
are you sure all initialized sections of the second program (using the
CSL) are transferred correctly during bootload? I recommend to generate a
linker map file and check the 6713 memory against the map file after
bootloading.
Does the reset vector jump to the correct program entry point (typically
c_int00) ?
Best Regards,

Dear Adolf Klemenz,jeff
I solve this problem.
remove link cmd file "-cr" item.
thank your helps!

If you remove -cr option, then your project will use -c option, which means "load-time" initialization. In this case
your C5402 host program has to initialize all C variables via HPI, as the C6713 code won't do it at run-time (run-time
= "r" in cr option).
Your problem may be Ok for now, but I think it will come back when you increase the compexity of the C6713 code.
