RTC doesn't work?

Lukas Riezler
Hi ecos-guys :)
 
I've a question depending on the real time clock in eCos (I try a port for FM3).
It seems it isn't working!
 
The returned value of cyg_current_time() is always 0!
It also seemy cyg_thread_delay(100) doesn't work...
 
I tried a "hard" read of the value of the systick register, and this isn't 0!
 
while(1)
{
HAL_READ_UINT32(CYGARC_REG_SYSTICK_BASE+CYGARC_REG_SYSTICK_VALUE, timerVal0);
timerVal2= cyg_current_time();
 
printf("%u\n", timerVal0); //it's okay...i counts down!
printf("%u\n", timerVal1); //always 0 :-(
}

Any ideas where my problems are?

With kind regards, Lukas

i found a issue in your code, but i this is only a typo in the demo:

while(1)
{
HAL_READ_UINT32(CYGARC_REG_SYSTICK_BASE+CYGARC_REG_SYSTICK_VALUE, timerVal0);
timerVal2= cyg_current_time();
 
printf("%u\n", timerVal0); //it's okay...i counts down!
printf("%u\n", timerVal1); //always 0 :-(
}
