Honored ContributorAs I commented above, I confirmed that nios2-flash-programmer would fail with the same error message for the 230K board. I systematically went through the sequence of tests in the attached .txt file (it was too large post inline), and wouldn't you know it, it works fine now!
I have a second 230K board that I will try this on tomorrow. I wonder if the issue was not in the programmer, but in the NIOS processor. In the systematic tests, I configured the board with an .sof from the v11.1 zip - perhaps that design corrected the error that causes the programmer to fail ... My suggestion to you: 1) Configure your board with the factory_recovery/s4gx530_fpga_bup.sof 2) Then in a NIOS II IDE shell, change to the factory_recovery folder, and issue the command nios2-flash-programmer --base 0x8000000 --debug --dualdie restore_s4gx530_fpga_bup.flash and let me know if that works. Otherwise try the systematic steps in the .txt file and see where you differ. Cheers, Dave
