CFI-Flash & EPCS-programming in production

Hi, if the hardware consists of an EPCS device (for FPGA configuration) and a CFI-flash (for Nios software and serial number), how do I program both after hardware production via JTAG? In ...

damc,

Check out the Nios II Flash programmer's Guide for version 5.1 software.

http://www.altera.com/literature/ug/ug_nio..._programmer.pdf (http://www.altera.com/literature/ug/ug_nios2_flash_programmer.pdf)

It is located in the Nios II literature page - under Related Documents section.

http://www.altera.com/literature/lit-nio2.jsp (http://www.altera.com/literature/lit-nio2.jsp)

In Appendix C it covers "How to Install Nios II Stand-Alone Flash Programmer". I think this covers what you are looking for to save harddrive space for production programming.

You only need to install the Quartus II Stand-Alone programmer (on the Quartus II CD) along with the nios2-flash-programmer.exe copied from a PC that has the NIOS II kit installed. Then you can use the flash programmer in CMD line mode which should be the most basic way to program the flash using the Altera utilities.

I recommend to read the whole document as there are many improvments in the new flash programming tool - for example if you have the minimum system componets to interface with a flash chip you can use your own design to program the flash chip (it can save a step in the production programming flow and should make flash upgrade programming out in the field easier).
