Hi,
Yes I have checked and double checked the settings in AN730, I am using a max10 and an n25q128 qspi. I have tried both option 4 and 5 with the nios booting from qspi and executing in place and copying to ddr.
After more investigation I think I am running into:
https://www.altera.com/support/support-resources/knowledge-base/solutions/rd03172015_883.html Where as the nios I am using is a nios/e and the qspi is in a seperate clock domain it doesnt boot. I am trying to find a workaround without having to buy the nios/f license.
The example design I looked at from rocketboards (Altera MAX10 10M50 Rev C Development Kit Linux Setup (althought I am not trying to boot linux)) uses the qspi as the boot device but has a nios/f core.
I am using quartus 15.1 so I might give the latest quartus a go in case it has been fixed in a later version.
