Typically, I erase the flash first with this: nios2-flash-programmer --epcs --base=0x00000000 --instance=1 --erase-all and then program the hardware design with this: nios2-flash-programmer --epcs --base=0x00000000 --instance=1 ETF.flash and then add in the software design with this: nios2-flash-programmer --epcs --base=0x00000000 --instance=1 ETF_CPU1.flash When everything is working correctly, I get this output: <div class='quotetop'>QUOTE </div> --- Quote Start --- Erasing flash memory...
