"No CFI table found at address 0x00000000" with S29GL064A flash

hi,

I get "No CFI table found at address 0x00000000" with my custom board using S29GL064A flash.

this board was working during 2 years.

When I want to program its flash via JTAG (and Nios II), I get the error.

Have a look at the NIOS manual, It talks about override file for CFI flash. But where Can I get it for my S29G064A ?

I tried to search in Forum too.

Have you got a work around ?

Explications ?

Regards.

    I am verifying deeply SOPC Builder (CFI Flash, Tsetup, Twait, Thold...tri-stated bus) and Quartus design files (connections, Byte_n...)

    I am manually writing an override_S29GL064A.txt with all CFI infos from Flash Datasheet.

    I think you should assign the base address of flash as 0x00000000 in SOPC builder that will solve your issue

    Thanks for answer. The Flash address base is already forced at 0x00000000.

    I think my Flash has its CFI table overwritten by bad commands. Is it possible ?

    Hello mmTsuchi,

    I think you have a simple hardware problem: it seems that D10 of your data bus has no connection to the Flash. Search for soldering problems and look if D10 is configured to the right I/O pin...

    Pin D10 problem because I get "0x04" data ? I hadn't thought before. Thanks you very much for reading, observing, answering and giving the clue (1.5 years after ;-))

    I had an oxidation on few boards, I will look at...
