alt_sys_init

Altera_Forum · ‎03-18-2006

I have made my own sopc component. I have also written an device driver to that component. I have also included the rigth file to /HAL/inc, /HAL/src and src/ under the SOPC builder. I then create an new prosject in nois2 ide. When I compile it, the compiler find the device driver files. But the *INIT and *INSTANCE is not included in alt_sys_init. How does I do that?.

I have tried to copy the /HAL/inc, /HAL/src and src/ to own folder under altera\quartus51\sopc_builder\components folder. But that doesent seems to help. I have also tried to copy the same files to the project directory in nios2 ide.

When I se in the component.mk the device drivers I made is there but not in alt_sys_init:

You should provide "init" and "instance" function for your own component.

For example, init and instance function

from altera_avalon_cf.h# define ALTERA_AVALON_CF_INSTANCE(name, dev) extern int alt_no_storage# define ALTERA_AVALON_CF_INIT(name, dev) alt_avalon_ide_cf_init( (void*)name##_CTL_BASE )

I recommend you to skim source codes in nios2\components

about init and instance source code
