PCD: Option invalid No PLL option
PostPosted: Mon Nov 16, 2009 11:45 am     Reply with quote

This is the settings for PIC24.
Code:

#include <24FJ256GB110.h>
#device ADC=10
#device PASS_STRINGS=IN_RAM

#FUSES NOWDT                    //No Watch Dog Timer
#FUSES NOJTAG                   //JTAG disabled
#FUSES NOPROTECT                //Code not protected from reading
#FUSES NOWRT                    //Program memory not write protected
#FUSES NODEBUG                  //No Debug mode for ICD
#FUSES ICSP1                    //ICD uses PGC1/PGD1 pins
#FUSES NOWINDIS                 //Watch Dog Timer in Window mode
#FUSES WPRES128                 //Watch Dog Timer PreScalar 1:128
#FUSES WPOSTS16                 //Watch Dog Timer PostScalar 1:32768
#FUSES IESO                     //Internal External Switch Over mode enabled
#FUSES NOCKSFSM                 //Clock Switching is disabled, fail Safe clock monitor is disabled
#FUSES NOOSCIO                  //OSC2 is clock output
#FUSES HS                       //High speed Osc (> 4mhz for PCM/PCH) (>10mhz for PCD)
#FUSES NOIOL1WAY                //Allows multiple reconfigurations of peripheral pins
#FUSES WPEND_LOW             
#FUSES NOWPCFG               
#FUSES NOWPDIS               
#FUSES WPFP0   
#FUSES PR_PLL                   //Enable PLL for primary oscillator?
#FUSES PLL2                     //Divide By 2
#FUSES RESERVED                 //Used to set the reserved FUSE bits
#FUSES DISUVREG       

#use delay(clock=24M, crystal=8M)

And this is the error:
Quote:

Executing: "C:\PCD4099\Ccsc.exe" +FD "main.c" +DF +LN +T +A +M +Z +Y=9 +EA
*** Error 99 "C:\test\main.h" Line 28(5,34): Option invalid No PLL option

What I'm trying to do is to change the HW external OSC.
The external osc was 25 MHz but because of testing, I have to switch it to
8MHz. So we made HW changes but when I compile the program I get
error, written above.

You may have revealed the cause of problem by playing around with the settings...
Basically the below line is wrong:
Quote:
#use delay(clock=24M, crystal=8M)

24M isn't a valid 24FJxxGB core clock, it has to be 32M. Curiously, PCD, that is ignoring all kind of defective settings
otherwise, is very critical in this point. It's also extracting some #fuses values from the #use delay entry, but you
better specify them separately, because some are extracted incorrectly. Omitting #fuse PLL2, that can be extracted
from the delay entry gives a PLL12 value...
