STR712 Clock

Hi All

I am using the IAR STR712 KS kit. I modified the rccu example that comes with the STRxLib so that MCLK and PCLK1/2 are all on 32MHz. The LED is also toggled. Code are listed below:

RCCU_Div2Config (ENABLE);

RCCU_FCLKConfig (RCCU_DEFAULT );

RCCU_PCLKConfig (RCCU_DEFAULT);

RCCU_MCLKConfig (RCCU_DEFAULT);

RCCU_PLL1Config (RCCU_PLL1_Mul_16, RCCU_Div_1) ;

while(RCCU_FlagStatus(RCCU_PLL1_LOCK)==RESET);

RCCU_RCLKSourceConfig (RCCU_PLL1_Output) ;

MCLKval=RCCU_FrequencyValue (RCCU_MCLK);

APB1CLKval=RCCU_FrequencyValue (RCCU_FCLK);

APB2CLKval=RCCU_FrequencyValue (RCCU_PCLK);

// Configure P1.8 as Output Push-Pull

GPIO_Config(GPIO1, 0x0100, GPIO_OUT_PP);

GPIO_BitWrite(GPIO1,8,1);

while(1)

{

delay(); // simple for loop

GPIO_BitWrite(GPIO1, 8,~GPIO_BitRead(GPIO1,8));

}

My problem is that the code is executing for a few minutes and then it stops. Does anybody know what can be wrong?

Cheers

Hi All

I have found the problem. In the end it had nothing to do with the clock setup, but it was due to faulty HW!!

Hi Zouh

Yes, I can confirm that there was some hw fault (dry joint, or something) on my STR712 KS kit. I had it replaced and my code is working fine now.

Thanks,

Gawie
