Hi all,

I want to store both hardware (FPGA configuration data) and software image into EPCS.

There is nothing wrong with me and you. The error is due to a bug of Nios II version 1.1. You'll find infos at Altera.com->support->intellectual property->NIOS II->NIOS II Development Kits Errata. A patch is needed to correct that problem.

Now I have downloaded the patch and I can boot from EPCS now. The patch can be obtained from ftp://ftp.altera.com/outgoing/download/ni...oader_patch.zip (ftp://ftp.altera.com/outgoing/download/nios/nios2_1.1_epcs_boot_loader_patch.zip).

There are many bugs inside Nios II 1.1. So if any question, you can first go to see errata info at altera.com. Perhaps nios II 5.0 can avoid these mistakes. Quartus II 5.0 and Nios II 5.0 will be released recently.

Especially thanks to Mike for his help!
