Programsize problems in FlowCode 7?

[Andreas]

Hi

Recently i have started using FlowCode 7, instead of FlowCode5, and in connection to this i have some programs in FlowCode 5, which i would like to continue to work with in FlowCode 7. But this isn't all without problems:

I have a file which was perfectly compiled, and worked fine on my PIC-microcontroller, when I was working with it in FC5. The compiler even said that about 13% of the ROM-space and more than 50% of the RAM-space was unused on the PIC.

When I tryi to compile the same program through FC7 i get following error

After searching the internet, i may have found out that it is because the microntroller is running short on space
I would like to hear if someone here can confirm this. The reason i'm curious is that the assembly-file tells me the following

And to me that looks like none of the banks is full. Maybe these details are not updated correct when the error occurs, but the whole file seems to be updating every time i try to compile.

Hi Andreas,
Could you attach the project.msg.txt file?
This has a Memory Summary section that will help.
The different compilers used between V5 and V7 can easily be 10% different in memory usage, both up and down,
so that 13% free ROM space sounds tight if the V7 compiler is using more ROM space for your particular application.

Hi

Thanks for the answer

The error was on my shoulders. I had forgotten that i had in-commented some code wich was not used, and because it was driving a LCD-display, this of course took a lot af program space.

But everything works fine now.
