Re: WDT reset while in an ISR

2006-04-18 by brendanmurphy37

Jaya,

You can deny it all you want. The fact is that in:

http://groups.yahoo.com/group/lpc2000/message/15370

you made the following assertion:

"It is because the watchdog timer on LPC is not wired to the Reset
interrupt priority level of ARM7.  Thus the Data Abort exception that
you are not dismissing locks out watchdog reset."

As I pointed out, this has no factual basis whatsoever. 

All Ralph and I asked you to do was provide some proof to the 
contrary. I've now given up on this, as asking you for evidence for 
your claims gets nowhere. Denying you made them in the first place is 
downright bizarre: the evidence you made the claim is there for all 
to see.

I will agree with one thing you say: "this kind of argument gets 
nowhere".

Brendan.
