ERROR Origin Exceeds $1F0 limit - what does this mean?

Chris_D

Hi everyone,

I just did a bunch of editing to my program and now when I compile it I get the following error

ERROR Origin Exceeds $1F0 limit

This pops up on a line where I declare a variable with the RES statement...

DY Res 1

Which is in the middle of a several more Res statements.

What is this error and what should I look for to fix the problem?

Thanks
Chris

So far I did not face this problem.

But it looks like you exceeded the boundaries of PASM. As you know you only have a limited amount of COG-RAM. The variable reserved with the RES statement simply popped out of the usable COG-RAM. The last 16 registers of COG-RAM are already reserved by the special function registers.

The assembler keeps a program counter which can be reset with the ORG statement. When this counter reaches $1F0 and you try to assemble something there, you get this error message. Essentially, your cog program is too big for the available cog memory.

Thanks much guys, I was afraid that was what the problem is. Looks like I have to figure out another way to "Skin this cat".

Thanks again!

One way I have used is to re-use the initialisation portion of pasm as variables once that particular instruction has executed.

Cluso99,

I never thought about that angle. I do have a number of variables being setup at the start of the code. Once that step is done, I don't need that code. I don't know if that would free up enough space buy I will have to look into that.


Thanks

Chris
