NIOSII Boot Configuration with EPCS and JTAG-SFL

Hello, i have a problem with configuring and booting my system from an epcs device. The topic is more about the correct design-flow, so i think this should be the right sub-fourm. the test...

Hi lodentoni,

As Daixiwen told --device=EPCS128 isn't actually relevant. I checked my design and it's the same. So forget about the EPCS128.

I am also trying to program my board with FPGA configuration and NIOS s/w, but not able to succeed. You need to program the FPGA with *.sof, reset the board so that FPGA is configured before you use the Flash programmer from NIOS IDE.

If EPCS device is not getting detected even after programming FPGA, then you need to check whether the EPCS flash controller pins are exported to top level or not in FPGA design.

I tried flash programming indirectly without using NIOS IDE and itseems to be working at the moment. (used the commands from http://www.alteraforum.com/forum/showthread.php?t=31375&p=127299#post127299).

Best Regards,

Laland
