Is flash access Nios II/f only

[meenalkb]

Hi,

I've been using the C10LP dev kit to test out the XIP option from EPCQ flash. This works fine with a Nios II/f core but not a Nios II/e - I assume this is because II/f provides an instruction cache.

Now, my question is, for general flash access, e.g. to read/write calibration data, would I still need to use the II/f? Or would the II/e support this?

Also, I can't find any info regarding licensing requirements for II/f - are there any?

Many thanks

Nios II e/f can write and read data from flash.

For Nios II licensing, you can refer to below:
