DE0 Nios II EPCS boot

Hi crts1973,

Have you solved the problem?

Recently, I got the same mistake.

I have successfully used the flash programmer to load my .sof and .elf files onto my epcs64 chip with Nios II SBT. I used Cyclone IVE EP4CE6F1717.

My SOPC builder has SRAM,EPCS controller, sysID,JTAG,PLL,CPU,pio_led.I have set the reset vector to the EPCS controller,exception vetor to SRAM.

The question is when I used the niosII command shell order :nios2-flash-programmer --base=0x00000000 \--epcs hello_world.flash

There is an error:No EPCS registers found: tried looking at address 0x0000100, 0x00000200, 0x00000300 and 0x00000400

I have tried ensuring the jtag_debug_module_reset output from theNios II Processoris connected to the EPCS Serial Flash Controller reset input, but donnot work!

Can you give me some help?

Thanks !

Sincerely Luke.
