Hello All,
I am trying to find out the maximum code address used after linking. Is there a global that the linker produces that contains the code size?
This is to speed up a program checksum calculation routine which can ignore the unused area after the end of code.
At present the code size is 256K, but can grow to 512K, I need the time to be as short as possible.
Obviously as time goes on the routine will take longer to execute, but initially will be shorter.
Thanks in advance.
if you're not using IAP, why not rely on the map file / scatter file ?
Tamir,
Thanks for the info, however this is a runtime calculation that I need to perform.
To ensure that the code version and the code integrity is correct we have to request a checksum routine periodically/manually.
This is to ensure that the code in the unit is 100% correct.

Shouldn't your integrity test walk through the full flash?

HI.
yes. i always put a copywrite msg and version infermation at the end of image and do a check sum test on all of it.
Always yo're freind.
