I want to continue on this old thread but adding new conditions for the same error.
I'm getting exactly the same error:
No EPCS layout data - looking for section[EPCS-FF]
Unable to use EPCS device
Leaving target processor paused
Error Code: 8 for command ...
But a singularity is that I'm only getting it when programming a certain system. So it should be an error in the description (Qsys). The only difference between this system is that I added SDRAM, but it works when running on Nios II HW so I'm guessing SDRAM is not the problem, or is it?.
*Should I use a tri-state?
