hi,The design is cyclone iii 3c55 with EPCS128. There is epcs controller in NIOS design. The sof and elf is ok when i use "run as hardware". But the software did not automatic load when power-up. The steps are most followed in this forum: " sof2flash --epcs --input=hw.sof --output=hw.flash elf2flash --epcs --after=hw.flash --input=sw.elf -output=sw.flash # flash EPCS first with FPGA configuration nios2-flash-programmer --cable='USB-Blaster [USB-0]' --epcs --base=0x21000 hw.flash# flash EPCS with Nios firmware nios2-flash-programmer --cable='USB-Blaster [USB-0]' --epcs --base=0x21000 sw.flash " I also tried the jic file. the software still cannot load after power-up. One thing I noticed, after power-up, when i run "nios2-terminal", I can see the result of software running. To my understand, nios2-terminal did not download the software (am i right?). But if i did not run "nios2-terminal", software did not run. What is the problem with my steps? or is there anything I need to check based on the thing of "nios2-terminal"? I use nios2-10.0 sp1. I suppose there should no epcs patch issue like 9.x. Thanks very much,
Hi,I have almost the same problem. Does your software start if you do: nios2-flash-programmer --epcs --base=0x21000 --go after power up? This will poke my software into starting, but I can't get it to start automatically at power up. Mark.
The nios2-flash-programmer has a bug in it, 9.1SP2. When you program EPCS with it, it does not work. Create programming file using Altera Stand Alone Programmer, then burn the file into EPCS.
