Tool/software: TI C/C++ Compiler
I need to port a function from the DSP core to the PRU0.
These are the steps performed:
- created a test.c file with the function
- compiled test.c using: clpru test.c, this generates a test.obj file.
- created a c array file using hexpru --array test.obj
- on main() of the DSP code c array is called by
PRU0_DisableAndReset();
PRU0_Load(PRUCode, (sizeof(PRUCode)/sizeof(int))); //PRUCode is the c array
PRU0_Run();
the PRU code is:
void PRU0_DisableAndReset(void){
HWREG(SOC_PRUCORE_0_REGS) = PRU_CONTROL_ALLDISABLE;
}
void PRU0_Load(const uint32* pruCode, uint32 codeSizeInWords){
uint32 i;
uint32 *pruIram;
pruIram = (uint32 *) PRU0_PROG_RAM_START;
for(i=0; i<codeSizeInWords; i++)
{
pruIram[i] = pruCode[i];
}
}
void PRU0_Run(void){
HWREG(SOC_PRUCORE_0_REGS) = PRU_CONTROL_COUNTENABLE|
PRU_CONTROL_ENABLE|
0x00000001;
}
The function ported is not executed after PRU0_Run(), what could be the problem?
Note creating a c array using pasm PRU_gpioToggle.p and using it with the PRU0 functions actually works, is there a parameter that must be set when running the clpru and hexpru tools?
