Hi,
Thanks for the reply. I changed the code as shown below but still WDT is not
enabled.
void start_wdt(void){ PM->APBCMASK.reg |= PM_APBAMASK_WDT;
WDT->CTRL.bit.ENABLE = 0; while(WDT->STATUS.bit.SYNCBUSY == 1);
WDT->CTRL.bit.ALWAYSON = 0; while(WDT->STATUS.bit.SYNCBUSY == 1);
GCLK->CLKCTRL.reg = (uint32_t)((GCLK_CLKCTRL_CLKEN | GCLK_CLKCTRL_GEN_GCLK4 |
(WDT_GCLK_ID << GCLK_CLKCTRL_ID_Pos))); while (GCLK->STATUS.bit.SYNCBUSY);
WDT->CONFIG.bit.PER = 0x7; WDT->CTRL.bit.WEN = 0;
while(WDT->STATUS.bit.SYNCBUSY == 1); WDT->INTENSET.bit.EW = 0;
WDT->CTRL.bit.ENABLE = 1; while(WDT->STATUS.bit.SYNCBUSY == 1);
return;}

Subject: Re: [riot-users] enabling WDT on SAM R21
Hi Abdul,
I haven't got a concrete answer for you but:
Is the APBA clock for the WDT enabled in the power manager
(APBAMASK register)?
Is the GCLK generic clock selection enabled (CLKCTRL register)?
Best,
Peter

Hi,
Can anybody help me in enabling the wdt sam r21? I tried
the following code segment but didn't enable the WDT. Am I
missing anything here?
void start_wdt(void)
{
WDT->CONFIG.bit.PER = 0xB;
WDT->CTRL.bit.WEN = 0;
while(WDT->STATUS.bit.SYNCBUSY == 1);
WDT->INTENSET.bit.EW = 0;
WDT->CTRL.bit.ENABLE = 1;
while(WDT->STATUS.bit.SYNCBUSY == 1);
}
and in the main loop, I used WDT->CLEAR.bit.CLEAR = 0xA5;
to clear the WDT counter.
Thanks
Abdul

Hi Oleg,
Thank you.
Hi Hauke,
Can you please help me in this?
I fear I can not really help, aside from telling you that I
have just taken on the work to fix the radio driver. I hope
I will be able to pull request a fixed version next week...
Cheers,
Hauke
Thanks

Just yesterday I learned that there is probably a bug in the SPI driver that
may cause this problem. Maybe Hauke can tell more about this issue.
Cheers,
