@ Kevin

too bad that the nios forum lost the thread, there was a list what devices were working (without any modification)

Michael,

Have you searched the Google cache for the lost pages? I had a go and found a lot of threads (some by you) but wasn't sure which one you were referring to. Here's the content of one possibility:

Today i have replaced an Altera EPCS by a Spansion S25FL064A0LMFI001

If, as mentioned bevore here, flash override has the following entry :

[EPCS-010216]# EPCS64N (Spansion-lead-free) S25FL064A0LMFI001

sector_size = 65536

sector_count = 128

I can successfully Blaster this device and will receive the following output :

EPCS signature is 0x16

EPCS identifier is 0x010216

Using EPCS size information from section [EPCS-010216]

Device size is 8MByte (64Mbit)

Erase regions are:

offset 0: 128 x 64K

In Addition i have replace an EPCS16SI8N by Numonyx M25P16-VMN6P

EPCS signature is 0x14

EPCS identifier is 0x202015

Using EPCS size information from section [EPCS-202015]

Device size is 2MByte (16Mbit)

Erase regions are:

offset 0: 32 x 64K

So M25P16-VMN6P is detected as EPCS16SI8N and can be blasterd too, what tells us that ....

Thanks for all replies now i have some much cheaper first choices and a good proven Altera second source :-)
