56F8323 How to put code into bootsector...

Tomppi — Wed, 27 Aug 2008 18:35:05 GMT

Hello,

I am targeting 56F8323 and ran out of PMem. I am using CW 8.2 with PE and have no Bootloader.
Can I put a part of the program into the Bootloader segment? How?

Does it need large memory model?

Thanks

Tamás

Hi,

If you're using the small memory the size of code is limited:

— Compiler generates a more efficient switch table, provided that code fits into the range 0x0—0xFFFF.

There is a table showing the memory ranges:

Section Small Model Large Model
Size Range Size Range

CODE
(P: memory) 128 KB 0 - 0xFFFF 1 MB 0 - 0x7FFFF
DATA
(X: memory) 128 KB 0 - 0xFFFF 32 MB 0 - 0xFFFFFF
DATA
(X: memory)
character data 64 KB 0 - 0x7FFF 16 MB 0 - 0x7FFFFF

If small memory is limited for your project, we recommend you to switch to the large.

Regards

Pascal
