Hallo,
Sorry if I broach the subject EPCS-16 again, but I have a big
problem and can not find a solution so far.
I have 2 DE0-Nano boards. One is working fine, the the other
makes problems, only when I try to flash my sof+elf design to EPC.
Enclosed, please find my test design and the error message file
from the bad DE0-Nano board.
My design is based on SD-RAM but I have the same problem if
I use the FPGA onboard RAM.
Very funny is that I am able to flash the jic file via
Quartus programmer on both DE0-Nano board. So, I think the problem
is not related to a faulty DE0-Nano board.
I am using Quartus II 11.1 SP2 and NIOS II 11.1 SP2
Does anyone know if there is a hardware revision problem within
the DE0-Nano board ? Could it be raise conditions and a fix is
already available ? I will order an additional DE0-Nano board
but if someone ca try to run my test-design on your Nano board
would also be a great help.
Any other ideas , concern is welcome.
Many thanks in advance,
Reinhard
