Why do I see the Error "Operation failed" when "Run As > Ashling RISC-V (auto-detect) Hardware Debugging" in RiscFree* IDE? - Why do I see the Error "Operation failed" when "Run As > Ashling RISC-V (auto-detect) Hardware Debugging" in RiscFree* IDE? Description Due to a problem in the Quartus® Prime Standard Edition Software version 22.1 and earlier, if a 16-bit Data Width Avalon® Memory Mapped Slave (e.g., OCRAM) is connected to Nios® V/m processor as Instruction and Data memory, it will result in below error when you run " Run As > Ashling RISC-V (auto-detect) Hardware Debugging " in RiscFree* IDE: Resolution To workaround this problem, add an Avalon® -MM Pipeline Bridge between your Nios® V and your slave memory (e.g., OCRAM) in Platform Designer.
