24FJ64GA004 Code suddenly not working anymore. Possible cause Clear command

[diebobo]

Hi Les,

I got a project which doesn't run anymore with the latest compiler, and with doensn't run anymore i mean that the CPU doesn't even power up correctly. Last compiled +/- 1.5 years ago it still worked.. I managed to delete everthing except the part which makes it not working anymore.. Below the code... If i delete the ISR part ( so bottom 3 line ) OR the Clear command at the top it works just fine.

I have searched the .ASM file and found some differences but i can't determine why or what.

Any thoughts ? Using latest compiler

Les, do you have a device of this family so you can test something for yourself ? I know have multiple programs written for a 24FJ64GA004 and they stopped working all together or incorrect after the change with the Clear command. Without the clear command they work correct, except with random / or old ram values and it really drives me crazy..
