Das U-Boot - Universal Bootloader

Hi Wolfgang,

Yes, I should have been more specific. 
How do you find out if a flash is compatible with CFI interface? 
I have:
 AMD AM29F040
 28F256J3C

Do you know if the above flashes are compatible with CFI?
Thanks

Claudio

You should be a bit more specific. Which "flash.c"? There are  nearly
200 files by that name in the U-Boot tree!

In general, you should use the CFI driver and fix any problems /  add
any code that might be missing there.

Best regards,

They weren't that important. They were merely at the top. The  people
who  really  run organizations are usually found several levels down,
where it's still possible to get things done.

Look it up in the data sheet.

Yes.

You don't have to worry about me. I might have been born yesterday...
but I stayed up all night.

By reading the data sheets which are available for free at the
manufacturers' sites.

    Claudio> I have:

Old AMD, not CFI-compatible.

    Claudio> 28F256J3C

Intel StrataFlash, CFI-compatible.
