I've been trying to instantiate a Nios II/e core with no success. I am using external SRAM, one 16 bit PIO, and a 50Mhz clock. I am able to synthesize the design, generate the sof file, and con...

Other than the LED I/O pins not being constrained, all timing requirements were met.

Same result: /s works, /e does not.

I don't remember how I connected the JTAG module. I'll check when I get home.
