Hi,

Greetings and welcome to Intel's forum.

May I know if you have include the header file <sys/alt_cache.h> so that the function alt_dcache_flush_all() can be called?


Hope to hear on your response.


Thank you.

Regards,

Kelly Jialin, GOH

Thanks for the update - I added the header file and the alt_dcache_flush_all() API call in my code but during compilation I get error like:-

undefined reference to `alt_dcache_flush_all'

Do we need to add any specific library for same to resolve?
