Overview
This chapter lists troubleshooting tips for the Nios II Flash Programmer. Each section
in this chapter describes a common issue you might run into when using the Nios II
Flash Programmer.
Start Button Grayed Out in the Flash Programmer GUI
In the Nios II Flash Programmer GUI, even after a flash programmer configuration is
opened, the Start button appears grayed out.
Probable Cause
You have not fully specified the required parameters for programming flash memory.
Suggested Actions
■ Check the Problems tab for any information about what may be missing or
incorrect.
■ Make sure that your JTAG cable settings are correct. Specify the connection in the
Hardware Connections dialog box, by clicking Refresh Connections and Resolve
Names
, and selecting the Nios II processor that matches the value in CPU to
program flash .
■ Make sure that you have selected a file to program to the flash memory, and that it
appears with the correct Conversion Type and Flash Offset values.
"No Nios II processors available" Error
When you run the flash programmer, you get the error: "There are no Nios II
processors available which match the values specified. Please check that your PLD is
correctly configured, downloading a new .sof file if necessary."
Probable Cause
The flash programmer is unable to connect with a Nios II JTAG debug module inside
the FPGA.
Suggested Actions
■ Make sure that the FPGA is running a valid flash programmer target design. If not,
you need to configure the FPGA using the Quartus II programmer. Refer to
“Flash
Programmer Target Design” on page 1–3 .
■ If using the flash programmer from the command line, ensure you have specified
the proper --device, --cable, and --instance parameter values. Refer to
Chapter 3, Using the Flash Programmer from the Command Line for details.
