Description
Due to a problem in the Quartus II software® version 13.1, some of the NIOS® II EDS utilities may fail with no error output or messages when run on a Windows PC.
The affected utilities are: sof2flash, elf2flash, elf2hex and bin2flash
Resolution
To work around this problem in the Quartus II software version 13.1 on Windows:
- After opening the NIOS II Terminal, set an environment varibable called QUARTUS_BINDIR to /bin
- export QUARTUS_BINDIR=/bin
- Open the Nios II Command Shell from Qsys via the Tools menu, then run the required utility
- Run the required utility from a Linux installation of the Quartus II software version 13.1
This problem is currently scheduled to be fixed in a future version of the Quartus II software, and this solution will be updated as other workarounds are finalised.
