I have a project that was built in MPLAB 8 using the Hi Tech C compiler. When I load it into MPLAB 8 to program a device I get a checksum (I use Unprotected checksum), then when I load it into MPLAB X IPE I get a completely different checksum. Is there a reason for this? Is there anyway to prove that both of these checksums are from the same file?

One thing I have notices is that the first 4 digits of the ID Memory in MPLAB 8 match up with the CP=OFF Checksum in MPLAB X IPE. Is this good enough to prove that the file is the same?

I hope this makes sense – any help is appreciated
