[SOLVED] Error - section 'MAIN_PROG' can not fit the section. Section 'MAIN_PROG' length=0x000

JohnJohn20 · May 15, 2016

Hi. I am building a project using the PIC16F818 and when I try to build the asm code I get this error:

Code:

Error - section 'MAIN_PROG' can not fit the section. Section 'MAIN_PROG' length=0x00000462

My script contains tables and when I trim them down a bit (about 40 lines) the script builds OK so it looks like my main program is too big.

However, when it does build OK and I check the memory usage it is using less than half.

So, is it possible to put parts of the program in other memory blocks or do I just need to trim it down a bit for this chip.

I have attached a copy of the asm file.

Thanks Chris

A came across a similar issue a long time ago programming in C, and had to turn around by splitting a big array into several smaller ones. In assembly everything becomes even more difficult to manage.

Thanks Andre. I guess what I am really asking is how should I know if it is a matter of my script being too long.

The 16F818 datasheet says it has a program flash memory of 1k x 14. How does that relate to the number of lines in my asm script?

And splitting the table into doesn't help.

That is the problematic file, but here it is copied and pasted straight out of the MPLAB application:

Code:

Thanks Xenos for doing all that, I am still not sure why it doesn't build. The program size is 0x462 bytes = 1122 bytes.

Mine will build when the program file is less than 1024 bytes. The 16F818 datasheet says that it has a program flash of 1k 14 bit words which must be enough to hold the 1024 bytes of program instructions.

But it is unclear to me why your MPLAB allows a program script size 0x462 (= 1122 bytes) to build.

Are you sure you are not building it for a 16F819 (which is the same as the 16F818 except it has a 2k program flash)?

Just a guess:

Are you running the code in Debug or Release mode ?
In general, debuggers take some part of the microcontroller's resources.

Chris

of course, Check message #6 again, it's there:

Code:

Make: The target "T:\dropbox1\pic\eda7m8.cof" is out of date.
Executing: "C:\Program Files (x86)\Microchip\MPASM Suite\mplink.exe" /[U][U][U][FONT=Arial Black][B]p16F818[/B][/FONT][/U][/U][/U] "main7e.o" /u_DEBUG /z__MPLAB_BUILD=1 /z__[B]MPLAB_DEBUG=1[/B] /m"eda7m8.map" /w /o"eda7m8.cof"

Debug information is on.
Why don't you post the entire project in a .7z file?
