assembly crashes

Erik Friesen

Why in the world would adding an unused object in the top cog crash the assembly cog?· For example why should adding an object to fullduplexserial cause a crash?·

Is there anyway aside from using wr-byte-word-long the crash outside cogs?

Here is some code.· It is not complete, only to show how I am passing and using my pointers.· It may very well be flawed.

I am calling it like this,· object.start(@led,@code,@batlow,@bathigh)

var
long pointers[noparse][[/noparse]4]
 
pub start (ledpointer, codeokpointer,batlow,bathigh)
pointers[noparse][[/noparse]0]:=ledpointer
pointers[noparse][[/noparse]1]:=codeokpionter
pointers[noparse][[/noparse]2]:=bathigh
pointers[noparse][[/noparse]3]:=batlow
 
cognew(@entry, @pointers)
 
dat
 
                    org
entry   mov     t1,par
        rdlong  ledp,t1
        add     t1,#4
        rdlong  codep,t1 
        add     t1,#4
        rdlong  bathip,t1
        add     t1,#4
        rdlong  batlop,t1
 
'to send to the outside world
 
        wrlong    missed,codep
        wrlong    blo,batlop
        wrlong    bhi,bathip

hippy

That code looks okay to me, so the problem is likely elsewhere.

And what happens when the last wrlong is executed ? is there a cogstop instruction, and endless loop or just nothing ? Chrashing may happen when the clk register is rewritten.

It was a (call main) instead of (call #main). duh.

call main, without '#' gives a compiling error last time I checked....
