Title: watchdog on 52259
Post by: neil on May 20, 2009, 05:57:20 PM

Hi Mark,
   I have enabled the watchdog on the 52259, with  "#define  WATCHDOG_DISABLE()       0".  Is it not possible to do breakpoint and stepthrough with this enabled?

  I am also about to test the bootloader, so I can do online firmware upgrades. Does the bootloader also use the watchdog?

Regards
Neil

Hi Neil

It is not possible to debug with enabled watchdog. See also the following: http://www.utasker.com/forum/index.php?topic=505.0

Note that the backup watchdog setting is retained through a reset so a power up is required to disabled it once it has been set running.
