hi,

The problem as follows:

#pragma PERSISTENT(firststartflg)

#pragma location = 0x20002144

char firststartflg = 0 ;At this point, Why is the generated bin file 512M ?

However,

#pragma PERSISTENT(firststartflg)

#pragma location = 0x2005

char firststartflg = 0 ;

#pragma PERSISTENT(firststartflg)

#pragma location = 0x20002144

char firststartflg ;At this point,the generated bin file 512M;

My requirement is to define a variable in memory that will not change at every startup, and the generated bin file should be 128K;

Thank you very much!

Please see this forum thread for some background on binary files. When the variable firststartflg is placed at a high address, and initialized, it amounts to creating an initialized section far away from all the other initialized sections. This means a large hole in the binary file, which must be filled. In your case, I suspect the best solution it to put firststartflg at an address right next to all the other initialized sections.

Thanks and regards,

-George

Thank you very much for your reply！
now，The starting memory address of cc1310 is 0x20000000，I want to keep the variable firststartflg is placed at memory. Any good solutions？

I still don't understand why you cannot put all the initialized sections, including the one for firststartflg, close together in memory.

Thanks and regards,

#pragma PERSISTENT(firststartflg)
#pragma location = 0x20002144
char firststartflg = 0 ;

I use it this way；How to make the generated bin file is 128K?

If the variable firststartflg must be persistent, and at an address far away from all the other initialized sections, then I do not see a way to solve your problem.

Thanks and regards,
