Hi Kelly,

a colleague managed to get an ID from the config flash. I compared his project to mine and the only difference was that in his platform designer his NIOS II, flash controller and other peripherals are all driven by a clock of 160MHz, mine was driven by 100MHz clock.

Changing my project to 160MHz seems to allow me to talk to the device. This doesn't make any sense yet.

No relevant warnings appeared during the project compilation stage, so as for why making the clock change makes it work I am unsure

best regards
