Hi Jiri,
I have two Fujitsu different FRAMs running with the stock at25 driver. I set
the page size equal to the device size (as FRAMs have no pages).
Are you able to run your FRAM with the unmodified driver?
I assume that getting the device geometry from the chip is vendor specific (in
contrast to flash devices which have standard commands for this). I suppose
that there is no much value getting vendor specific information from a chip. If
the drivers knows the vendor, it should also know the chip (e.g. from the dt).
Hi Christian,
main purpose of this patch is to get serial number from this chip. I
don't have it done yet, in older kernels I expose it as separate file in
sysfs, but in this kernel no luck. So a post first things while I'm
working on sernum exposing.
Does your chip has serial number? Can you read it?
Any help welcomed.
Thanks
Jiri
PS: If standard EEPROMs has some commands to get size etc., why it's not
used? I guess that size is increased as time goes while board is still
the same, so isn't it annoying changing dt every new lot with bigger
eeproms.
