MCU is MC9S12XEQ512,compile the offical bootloader project and get one glo and one s19 file in the directory 'bin'.


In the project's prm file,I get source codes like:

VECTOR 0 _BootStart

VECTOR 1 _BootStart

VECTOR 2 _BootStart

In s19 file,i get the expected code:


But in glo file,i get the unexpected code:



Description of PPAGE register in the datasheet,i get following words:

The fixed 16KB page from 0x4000~0x7FFF is the page number 0xFD;

The fixed 16KB page from 0xC000~0xFFFF is the page number 0xFF;

The 16KB page from 0x8000~0xBFFF mapped range is 0x780000~0x7FFFFF;


Upgrade processing use the glo file,but there is no Reset Vector Value(0xFFFA~0xFFFE) in glo file,how does this work?
