Thank you for viewing my post. In my program for a PIC16f690 I am working on, I am finding the following error:

Section '.org_2 can not fit the absolute section. Section '.org_2' start= 0x00000005, length=0x00001204

I have this file listed in source file as a .asm file which is correct. All other folders in my projects folder are empty. I know that I have not gone over a page boundary as I look at my program memory in MPLABx.

I have no "code" listings as I am in absolute and use "org".

I have org 0x00, and 0x04 but no other org accept for 0x05 just after MAIN in my program.

As per the datasheet, page 0x05 is the start of page 0 and 0x800 is the start of page 1.

Any suggestions would be of help to allow me to solve this issue I am having.

Thank you.

As I was looking through your code, I noticed that...

...oh, wait. There is no code.

 

It looks like you are out of program memory.
The 690 has 1000h (4096) words of program memory in 2 banks. Your error says the length of the segment is 1204h (4612) words.

Section '.org_2 can not fit the absolute section. Section '.org_2' start= 0x00000005, length=0x00001204

Time to start squeezing.

John,
Thank you for your "constructive" advice to help me try and solve this issue. I was wondering if that(1204h) was the total amount of used words. I will continue to squeeze.

Yeah, in midrange, each bump of the program counter is one 14bit word. Your case is a bit worse than that as the segment starts at 0005h meaning 5 fewer words available (you used some in the other segments at ORG 0 and ORG 004h). Also, don't forget that the code does not readily flow across the 2K bank boundaries without manually setting PCLATH bits - burning more code.

Aside: The marketeers used to like to compute the number of bits in the program memory (14*number of words) and divide by 8 to show more bytes of program memory to better compare with byte-oriented processors like the 8051... that generated a lot of confusion for new users.

But as long as you are squeezing, my personal advice is to squeeze a few bucks out of the coin jar and upgrade to 18F or at least 16F1xxx Enhanced Midrange. The effort will be way worth it.
Have fun!

 

John,
I had ordered a few PIC18F26k22 earlier this afternoon as I was looking for an upgrade (2 euarts, more port pins, etc) in a few peripherals to give me more room to 'grow'.
Thanks again. Enjoy your evening.
