Why does the Nios® V software fail to run after consecutive niosv-download commands on the same Nios V hardware? - Why does the Nios® V software fail to run after consecutive niosv-download commands on the same Nios V hardware? Description This issue may be seen in the Intel® Quartus® Prime Pro Edition Software version 21.3 and later when subsequently downloading and running the Nios® V software on the same Nios V hardware system. This is due to HAL or C runtime library not being initialized properly during the 2nd download. Resolution To work around the problem, follow the steps below: Edit the niosv-download source code (<Intel Quartus Prime>/niosv/bin/niosv-download-files/main.py) with the bolded argument. # Run GDB to load the program. GDB = 'riscv-none-embed-gdb' gdb = GDB gdb_args = [ gdb, '-batch', '-ex', 'set arch riscv:rv32', '-ex', 'set remotetimeout 60', '-ex', f'target extended-remote localhost:{gdb_port}', '-ex', 'load', '-ex', 'set $mstatus &= ~(0x00000088)', elf_file, ] Invoke the GDB server with the argument below when downloading the Nios V software using OpenOCD and GDB server. -ex ‘set $mstatus &= ~(0x00000088)’ This problem is scheduled to be fixed in a future release of the Intel® Quartus® Prime Pro Edition Software.
