Honored ContributorHow to use an EPCS Flash
Hallo together, I'm actually trying to save data from NIOS II into an EPCS64 device. My system contains an EPCS controller. But now the confusion is complete, there are so many files for usin...

The behaviour you described is quite strange... I can't explain it... It still seems that all init following last TIMER init are empty...

Maybe it is only a problem of presentment of eclipse, because the JTAG-UART for example (and anything elese which comes after EPCS Controller) works well. And this wouldn't be if the init wasn't called. Right? But with the call of the macros in main() I'm now able to debug the init. sequence. I will try that tomorrowar for epcs device.

Are there any other things to think about? Any other ideas why the open command always returns NULL? Because I can boot from this flash, it should work principally with this device!? Right?
