    DaveB123
    You are correct ! On the 281x devices, this flag is not reliable since the sampling window for the reset line is too short . On the 2833x/2823x devices, the sampling interval has been increased to allow more time for the reset line to go high after a watchdog reset occurs. Check Section...

    Hello, I'm finishing one of my projects on TMS320F2808 and now I want to detect situation when reset was caused by wdog. To simulate firmware stall I have added while(1); cycle into my code (inside one of events handlers). Reset occurs but WDFLAG is not set. What's wrong? Thank...

    Well, I still haven't solved this problem, but I discovered a strange fact. According to the SPRA958 if I set a break-point at the start of _c_int00 (0x3F64EF) and at the beginning of main() and program reaches the first one but never comes to the second - it's a watchdog timer issue. And I have...

    Hi there, We are currently developing the controller using F28335. And I'm implementing the Watchdog ISR code. In my WDT ISR code, I'd like to capture the address where the watchdog was occurred. I'll show the example code for your better understanding. Here is the test code...

  • Forum Post: Re: WDCR stuck during power cycle.

    Jeff Stafford
    Hi Tom, The WD is enabled at reset by default without any initialization code. If a WD event causes a reset then bit 7 in the WDCR is set as you describe the WDCR.WDFLAG bit. This bit will remain set until software resets it to 0. To reset it to 0 the code must use the EALLOW instruction to gain...

    Hi i have the following constellation. I set my device to Standby Mode and to save maximum Power i also power down the Flash. (FPWR = 0) Now i want to wakeup from Standby with the Watchdog. This works fine so far but my problem is i want a longer time for the device to be in Standby Mode before...

    Hi, Thanks for the post. My objective is to distinguish the resets caused by some external source or internal watch dog reset. As a primilinary step, without simulating any external reset code and after power up. I was checking the register WDCR if the flag WDFLAG is set or not. My observation is...

    Hello Mark, Thanks for the note. After going through some series of test, watchdog code is seems to work which means watchdog is able to reset the processor and set a flag. Due to hardware limitation, I was not able to check the XRS pin. When I changed my watchdog initilization to WDCLK = OSCCLK/512...

    Hi Jason, I tried a few things to go back to boot Rom. First I set GPIO34 to zero in code: GpioDataRegs.GPBCLEAR.bit.GPIO34 = 1; (what does digout mean?) Then I tried to cause SW reset by setting WD to zero: I did this based on http://e2e.ti.com/support/microcontrollers/tms320c2000_32-bit_real...

    Hi, I have two 28335 which behave different after watchdog reset. The first one the PLL is still active, the other one, the PLL is bypassed. The older one (DSP TMS320F28335PGFA CA – 89A23RW G4) does not reset the PLLCR.bit.DIV, so that the PLL is still active and the CPU clock frequency is...

    Hi all, I want to use the watchdog to periodic wake up from standby, check the adc and then go back to sleep. The watchdog is set to WAKEINT and works when system is not in standby.

    We're working with a TMS320F28069 ControlCard in a Rev-3 docking station, using CCS5 for debugging and DSP/BIOS 5.42. During normal stepping, after a few turns through our idle task loop, the processor appears to reset and the debugger reports the PC at 0x3FF4FA. The idle loop is simply checking...

    Hi everybody, I have the following situation: In an external interupt I must wait for a GPIO to go in H. So I have a while loop and in the condition I check the state of the GPIO.

    Hi, I am using F28335 with oscclk=20Mhz and Cpu clkin=100Mhz. If the control software crashes I need to reset the DSP in 300us time. But the shortest possible reset time for watchdog is 6,528ms in my configuration. Am i right? 6,528ms is not enough for me. So is there any other way to...

    Hi everybody! If the watchdog is set to interrupt mode, what happens if the execution hangs in another interrupt? The counter will expire, and triggers the watchdog interrupt, right? But can this interrupt be serviced? Thanks, Monica
