EPCS Flash Access on DE0 Nano (Qsys)

To support newly released flash memory devices which might have problems in the

CFI table, the Nios II Flash Programmer provides the ability to override CFI table

entries with flash override files. A flash override file lets you manually override

erroneous information in the CFI table, which enables the Nios II Flash Programmer

to function correctly.

you will need to create a text file that includes the missing informations:

<nios2_install>/bin/nios2-flash-override.txt

For example for DE0 NANO:

[EPCS-010216]# EPCS64N (Spansion-lead-free) S25FL064P

sector_size = 65536

sector_count = 128
