I've been trying to implement the watchdog timer on my Sharp79524 and it appears that the mutt is sleeping on the job! I believe I have it set up to trigger after about 3s of inactivity but it doesn't seem to reset the system at all. My setup method is as follows: 1) Write 0x00000090 to the watchdog CTL to set up for 2^25 counts of HCLK as the timeout period. This also stops an interr...

We are using Linux. watchdog timer implementation as follows: In the software setting the watchdog timer and on timeout it clears the hardware register which is used by the hardware to check if the system needs to be reset or not.

I am trying to change the watchdog prescalar in an ATmega32 application. The data sheet implies that the watchdog timer registers can be written at time with no special requirements. Is this the case? I am finding that the following code works in AVR Studio but not in the hardware. void WatchdogInit(void) { WDR(); WDTCSR = 8; // Set prescalar to ~1/4 second timeout. } Compiler i...

Randy Yates recently started a thread on programming flash that had an interesting tangent into watchdog timers. I thought it was interesting enough that I'm starting a thread here. I had stated in Randy's thread that I avoid watchdogs, because they mostly seem to be a source of erroneous behavior to me. However, on reflection I realized that I lied: I _do_ use watchdog timers, but ...

Hi, i'm working on a AT91SAM7X-EK development board, and i'm trying to figure out if the normal at91 watchdog behavior can be changed or workarounded because: "The Watchdog Mode Register (WDT_MR) can be written only once. Only a processor reset resets it. Writing the WDT_MR register reloads the timer with the newly programmed mode parameters." due to this feature, if i disable watchdo...
