Problems pasting PLL initialization from GEL to main

Include the following lines to ur main.c and call ProgramPLL_100MHz() at the beginning of the main function. Then compile, create led.bin using hex55 and load using programmer.out. I tested it yesterday and it worked.

#define PCGCR1   0x1c02
#define PCGCR2   0x1c03
#define CCR2     0x1c1f
#define CGCR1    0x1c20
#define CGCR2    0x1c21
#define CGCR3    0x1c22
#define CGCR4    0x1c23

void ProgramPLL_100MHz(void){

int i;

    printf("Configuring PLL (100.00 MHz).\n");
    /* Enable clocks to all peripherals */
    *(short *)PCGCR1 = 0x0;
    *(short *)PCGCR2 = 0x0;

    /* Bypass PLL */
    *(short *)CCR2 = 0x0;

    /* Set CLR_CNTL = 0 */
    *(short *)CGCR1 = *(short *)CGCR1@IO & 0x7FFF;

    *(short *)CGCR2 = 0x8000;
    *(short *)CGCR4 = 0x0000;
    *(short *)CGCR3 = 0x0806;
    *(short *)CGCR1 = 0x82fa;

    /* Wait for PLL lock */
    for(i=0;i<0x7fff;i++);

    /* Switch to PLL clk */
    *(short *)CCR2 = 0x1;

    printf("PLL Init Done.");

}

Thanks You for the answer.

I tried to do your comment, but the led again blinks very slowly (5-6 seconds), directly in CCS (RAM) the led blinks every second.

Have you another recomendation?

Thanks for your help.

Hi again.

I´m attaching mi principal code, thanks for your possible help.

    }

}

} 

Which version of hex55 are u using. I use 4.3.5 whic gives good speed. Refer to http://e2e.ti.com/support/dsp/tms320c5000_power-efficient_dsps/f/110/p/11099/43179.aspx#43179 to see which version of hex55 is slow.

Thanks Rijurekha for your help.

I tested the program with hex55.exe version 4.3.6, but doesn´t work. Then, i tested with hex55.exe version 4.3.5 and again doesn´t work, The last test was done with hex55.exe vesion 4.3.4 and nothing.

I am a little desperate with this, because another project doesn´t work when flashing.

Thanks for your attention.

Finally i´ve fixed the issue adding the function InitSystem() to the main code.

The blinking led is normal.

Hi  Nemanya, Am facing similar problem.

Actually am trying sample LCD code to boot from c5535 EEPROM. I now the procedure to convert the .out file to .bin.

Here i need is to include initialization part to sample lcd code. As you fixed this earlier by adding the initsystem() to main code. Can you please provide the total sample led program which having initialization to boot from EEPROM.

Thanks,

Kranthi.
