Problem using HAL Api

I found something new.

Changing "int alt_main(void)" to "int main(void)" in modified Hello_Led project

made it to call alt_sys_init() automatically before main function.

And, devices seemed to be registered in the alt_llist* list.

But, alt_flash_open_dev() still fails.

However, when I let a person who has the "NiosII Development Kit Cyclone II Edition" board

(I am using "NiosII Evaluation Kit Cyclone Edition")

do the samething, then, it seemed to work just fine(alt_flash_open_dev is returning other than 0).
