Hi Erwin and all,
here is the link of my flash, http://www.sst.com/products/?inode=41416
The datasheet talk about CFI compatibility, so the CFI probing should be
enough to detect it ?
Yes, the jedec probe is showing nonsense values in the mfid and devid
fields. Seems to display the flash memory address, so something is
really confused in the kernel, i will try to make clean.
I will going to disable 8 and 32 bit access, also, as you suggested.
Thanks,
Angelo

Hi,
of course you can add your own entry, you just need to know the erase
sectors of your flash. The preferred way is to use CFI, if your flash
supports that, however. I think that the missing jedec_probe entry isn't
the real problem in your case, since the manufacturer/device id from
your log do not sound reasonable. If you are using 16-bit mode only, you
can disable 1-byte and 4-byte access in the kernel configuration, that
will avoid some unnecessary probing.
I couldn't find your flash on the SST site, there's a SST39VF3201B
only??

Well, i am finding out that in jedec_probe.c, SST29VF3201B is not
supported, so ID cannot be detected.
Do you think i can add an entry for this flash by my own ?
Many thanks,
Angelo

I have a 16bit word, 4MByte flash, mapped at 0xffc00000.
Do i have to set this address somewhere in the kernel, to allow
mtd to
detect it ?
It would also be useful to know the manufacturer and part # of the chip.
Apologies if this wa mentioned and I missed it.
