#ORG error on 24FJ128GA006

I am receiving an 'Invalid ORG range' when attempting to use the full program memory space of the 24FJ128GA006 processor.

I wonder what you want to achieve with the said #org statement. Because you are assigning the full ROM area, except for the bootloader, no room is left for the application. #org statement with this syntax takes effect for the following function or const definition only.

By assigning the area below 0xc04 to the bootloader, the application code is automatically placed in remaining area.

How do you intend to assign the interrupt vectors in your design? I defined fixed vectors for all used interrupts in my application (Option A, direct mapping method in AN1157) and use #org statements to place the individual handlers to these addresses. Option B doesn't work due to limitations in PCD as far as I see.

I was trying to keep out of the area where the AN1157 bootloader is (since the PCD one is a little hokey). I read the CCS manual on the ORG command, but I think it got lost in translation as it was going to the brain (not a lot of sleep).

I will try blocking from 0x000-0xC00, since that is what I am trying to do.

I will post if otherwise.

Thanks!

I have assigned the bootloader memory range by importing it's image to the main application. The advantage is in creating a single production image containing the bootloader and the application code.

I wasn't able to get to the code last night (daughter was sick), but I hope to get to it today. I was thinking of using the non-remapped IVT code for AN1157. I was worried about the IVT range, since my initial main program with a timer did not function until I took the timer out.

Yes, as said, my example is also using direct mapping. The IVT entries are generated by the main application. Because the IVT is actually part of the protected bootloader image, all ISRs must be assigned to fixed addresses that are unchanged between software versions.
