No PLL option error - V4.128
PostPosted: Sat Jul 25, 2026 4:16 am     Reply with quote

Hello
I have an old program that I need to modify. The original was compiled with V4.128 (PCWHD). The problem is that the compiler has started giving me an "Option invalid No PLL option" on the #use delay line:

#use delay(crystal=25000000, clock=140000000, RESTART_WDT)

I am using the 33EP512MU810 chip. My chip selection and fuses are:

#include <33EP512MU810.h>
#device adc=12
#FUSES
#FUSES
#FUSES HS
#FUSES PR_PLL //Primary Oscillator with PLL
#FUSES CKSFSM
#FUSES BROWNOUT //Brownout reset
#FUSES NOPROTECT
#FUSES WRT
#FUSES NOAPROTECT

I suspect that the problem may be have been caused when I updated the other version I have installed (V5.082) to V5.124. I did try uninstalling both version and re-installing just V4.128 but I still got the same error. I need to use V4.128 as the old code does not work correctly with the newer compiler.

Any suggestions as where the issue may be?

Thanks
