16f690 doesn't work with second Page

Hi community,

I have a problem with my PIC 16F690. My program is now 2000 lines tall, and now I must use the second page. Normally it shout be no problem, but in my case it is.

The problem is that if I programming my pic with the source code form the MPLAB then the Pic doesn't work correctly. In the debugger of MPLAB it works correct.

I specify the second page at the program memory (org 0x800). When I'm looking in the listingfile, then i see that the source code of the second page is located at 0x800 forward.

Has someone a idea why it doesn't work in the physical Pic but in the debugger? or what is may mistake ?

cheers

I have scanned very quickly ! the data sheet and done a Google (Piclist), are you setting the registers needed to point to page 2 directly before you do a call to code there, and presumably, vice versa when going back to page 1. Some of your code would be helpful.

PBP takes care of paging ...

soooo, may be wrong forum for this kind of behaviour ??? :D

Hi Guys thanks for the response!

befor I change to another page I do pagesel "name of function" (page 2) and after a return I do an pagesel to page 1. At the end of page 1 i declare with org 0x800 the program memory for the second page.

org 0x800
#include <Main_Init.inc>

Everything after this lines is on the second page, right ? So all program code which is called will be called with pagesel, alternative with lcall.

That is an example for a call to the second page.
pagesel Init_ALL
lcall Init_ALL ; initialized all important registers
pagesel $

What is wrong on my version ??
