NIOS II and ASMI

Folks, Why is the ASMI interface considered a "legacy" peripheral in NIOS II when it has a set of functions in the NIOS II kit? Is anybody using this component with success in NIOS II?

Hi Edward,

>Did you roll your own because you could not get the supplied functions working?

No ... I never tried the supplied functions. I implemented the interface as part of u-boot

with Nios-32 ... before the IDE, and epcs programming via JTAG, etc. etc. So I just brought

the code forward and continue to use it with Nios-II.

And, as you may have detected ... it bothers me when I'm told I "must" use vendor-supplied

drivers ... I've been burned too many times 8-(

> There are no examples and I cant seem to get the library to link in.

If it's any help, you can download the u-boot code and see cpu/nios2/epcs.c:
