Binary file compiled with older version Bascom (quite old ac

If I ISP program (using Bascom 2.0.8.2) an old binary file that was compiled with a very old version of Bascom (oh, let's say 2.0.7.1), but haven't recompiled it in 2.0.8.2, there is nothing changed in the binary, correct? It should be loaded into the programmed processor exactly the same as it was compiled years ago, correct?

I ask because if I try doing the above, the loaded binary doesn't seem to run properly

(BASCOM-AVR version : 2.0.8.2 )

Hi,

What do mean with " doesn't seem to run properly"?

If the code that you write verifies than it's exactly the same code. The only Thing could be a small Change to the Hardware or maybe the fuse bits aren't being set correctly. Without more Information it's impossible to help more than this.

I have a 7 year old hex file that I can load onto the PCB and it works exactly the same (Compiled with 7.8? downloaded with 8.2)

hi
I had some surprises when I picked up old programs with new versions
for example Lbyte
I usually name some generic variables with a letter and type: Jbyte jword... it makes searching easier

but Mark had the same idea and since a few versions

see the help for reserved words
Additional, there are also these reserved words :

LBYTE , HBYTE, TYPE

what do you mean by binary file? the.bin generated by the compiler?
in this case take over the project and rebuild it with the new version

funny EDC I did the same comments !

Edc have you seen the comments in the forum "varius" on the HMI screens?

I think Ken is not talking about re-compiling his program.

He has the compiled program and is just downloading it to the micro, and now it doesn't work as it previously did.

As Dobson said, it is likely the Fuses are not configured as they were on the original board.

What one uses for an ISP programmer should make no difference at all.

Hi all, @KenHorse, can you tell us a bit more about the programmer you are using and other details of the binary you are having problems with - in particular its filesize and the specific micro you're trying to program, and what OS you're running?

I've discovered what I think is a bug in 2.0.8.2's programmer. The symptoms you are reporting are superficially consistent with the same problem. Rather than assume and reply here, I'll post a separate thread for the time being - but if you can answer the questions above that will help us help you - and also support (or disprove) the hypothesis that we are seeing the same problem.
