Thanks, Taz.

The thread you mentioned talks about using the older EPCS controller but I didn't see any new information.

FWIW I have setup a project for the Cyclone V GX Starter Kit (https://www.altera.com/products/boards_and_kits/dev-kits/partners/kit-terasic-cyclone-v-gx-starter.html) and have not been able to make it work either.

I do not see the flash data corruption on the starter kit, but I never see the NIOS boot as it should.
