Lpc2000

Hello everybody,

I am starting to evaluate LPC2100 family and I've got a question 
about interrupt vector 0x14, which is checked by the bootloader. Is 
there a way to tell the linker, that it must be an inverted checksum 
of remaining vectors? Or Philips ISP utility automaticaly sets it to 
a proper value?
Isn't there also a shortcomming in a bootloader logic? Suppose for 
example that the flash is unprogrammed (all vectors are 
0xffffffff's). So their checksum is 0, which for the bootloader is a 
valid program! Or may be the checksum, which is used is not simple 
EORing of all 8 vectors?

Regards,
Ivan
