Nios V/c issue: no valid Nios V instance - Nios V/c issue: no valid Nios V instance Hi, I have synthesised a Nios V/c (3.0.0)-based SoC on a DE0-Nano board, which was successfully configured using the quartus_pgm command via a Nios V-shell terminal in Quartus Prime Standard 24.1. However, when the niosv-download command is executed after generating BSP and ELF files, the following message appears on the display: ... There are no devices with valid Nios V instance(s) ERROR: Failed to generate OpenOCD config file. ... However, if the same Quartus project is compiled with the Nios V/c (3.0.0) core replaced by a multicycle Nios V/m (26.0.0) core, this error does not appear, and the program runs successfully. Could you please provide any hints on how to fix this error for the Nios V/c IP ? Regards, Domingo. Replies: Re: Nios V/c issue: no valid Nios V instance Hi Sue, Thank you very much for your quick reply. Regards. Domingo. Replies: Re: Nios V/c issue: no valid Nios V instance Hi Domingo, I'm sorry, but the Nios V/c will not support debug features until some time mid next year. As a result, features that need debug, like download, are not supported until then. Sue
