Hi AKAYA, Normally, your program’s entry point is the function main(). There is an alternate entry point, alt_main(), that you can use to gain greater control of the boot sequence. The difference between entering at main() and entering at alt_main() is the difference between hosted and free-standing applications.

thanks for the reply....

 

can we use both alt_main() and main() in same project?

if its possible then will the alt_main() fuction calls the main() function by default or we need to call the function explicitly

Hi AKAYA,

 

Kindly refer to 'Customizing the Boot Sequence' section in https://www.intel.com/content/www/us/en/programmable/documentation/mwh1416947091611/mwh1416946758774...
