TMS320F28035: PIE interrupt funtion name need change?

Part Number: TMS320F28035
Other Parts Discussed in Thread: CONTROLSUITE

I use ccs3.3 with dsp/bios 5.41.2.14, and some PIE interrupts used in my project, the question confuses me is that I could not use the default pie interrupt function name, 

i need to change the name, or the system collapses when power on. Take ADCINT1_ISR() for example.

In the .tcf PIE_INT1_1 configuration, the function is _ADCINT1_ISR, and "use dispatcher" is selected, in the DSP2803x_DefaultIsr.c, the function is like this:

void ADCINT1_ISR(void)

{

...............

}

Then build the project and program the flash, when power on, the system runs totally abnormally.

But if I change the funciton name in .tcf and DSP2803x_DefaultIsr.c, for example, change to ADCINT1_ISR0, then the system runs smoothly.

    You don't need to use the underscore '_' for the HWI functon.

    But if I detele the prefix ' _ ' in the HWI function, build error.

    Sorry, I'm a little confused. Can you list the .tcf and source code for working and not working? Your last post seems to contradicts the first post.

    In the non-working case, can you look at the mapfile? Is it pulling in ADCINT2_ISR from ControlSuite?

    Yes, map file can be seen, the project build process have no problem. what is the mean of "Is it pulling in ADCINT2_ISR from ControlSuite?"

    Thank you.

    I've placed ADCINT2_ISR0 in tsk.c. When I look in the mapfile I see this

    .text 0 0000962c 000000d0
    0000962c 00000028 tsk.obj (.text)

    ...
    0 0000962c _ADCINT2_ISR0

    So I know that I'm supplying the function.

    Are you using ControlSuite also? It has a ADCINT2_ISR function (which does nothing). When you are building are you using that function? You can look in the mapfile to see what source file the function came from.

    In my project ADCINT2_ISR is placed in DSP2803x_DefaultIsr.c, the map file:

    .text      0    003e85b3    00003555    
                      003e85b3    00000a26     ........obj (.text)
                      003e8fd9    00000793     ..........obj (.text)
                      003e976c    000005a8    ...........obj (.text)
                      003e9d14    0000052c    ............obj (.text)
                      003ea240    000004d9     ............obj (.text)
                      003ea719    000003dd     .............obj (.text)
                      003eaaf6    000003ae     DSP2803x_DefaultIsr.obj (.text)
                      003eaea4    00000317     ............obj (.text)

    003eab5a   _ADCINT2_ISR

    seems no fault found in map file.

    DSP2803x_DefaultIsr.c come from ControlSuite, I only made some modifications,

    for ADCINT2_ISR, only remove the interrupt key word, and insert my code:

    void ADCINT2_ISR(void)

    {

      PieCtrlRegs.PIEACK.all = PIEACK_GROUP1; 

     AdcRegs.ADCINTFLGCLR.bit.ADCINT2 = 1;

     Adc_Calc(); 

    }

    Where did you change the ADCINT2_ISR code? In ControlSuite or do you have it in a different file. Can you set a breakpoint in the ADCINT2_ISR function? Do not open any files though. Instead, open the disassembly window in CCS and enter ADCINT2_ISR into it. Then set a breakpoint on the first asm instruction. Run. What file is opened when the breakpoint is hit. Does the assembly match the C file?
