  The only thing I can see is that your res should come after your float declaration.
  
  

  delay   long  40_000_000
  time    res   1
  
  

  
  
  
  Its one of those things.

  you have to place RESs after anything else that's on the same cog. The long "delay" gets overwritten now - RES increments program counter but doesn't take up any space.

  All res declarations need to come at the end of an orged DAT segment. The way you've written it, the 40_000_000 you meant for delay gets loaded into time when the program is started via cognew.

  Two things are wrong here:

  My code is as follows:
  
  

  CON   
  
    _xinfreq = 10_000_000
    _clkmode = xtal1 + pll8x 
  
  PUB Main
  
    cognew(@entry, 0)
                                       
  DAT
  
  entry   org   0
  
          mov   dira, #1
          mov   time, cnt
  [b][color=red]        ADD   time,delay      'YOU NEED TO SET THE INITIAL CNT TARGET
  [/color][/b]        
  :loop   waitcnt time, delay
          xor   outa, #1            
          jmp   #:loop
  
  [b][color=red]delay   long  40_000_000      'ALL DECLARED DATA MUST PRECEDE ANY RES's[/color][/b]
  [b][color=red]time    res   1
  [/color][/b]
  

  
  
  
  I'm trying to toggle an LED on pin 0, the debug LED on the Hydra. But, it's not working, for some reason. Can anyone show me what I'm doing wrong?
