Does blackfin uClinux linux have fully support Spansion's flash ?
We currently use ST's M25P128 and we want to use S25FL128.
Thanks !

you can find all flashes supported by the Linux kernel in the driver:
linux-2.6.x/drivers/mtd/devices/m25p80.c

Just because the Linux kernel supports a specific flash - does not mean the BootROM for your specific part does. (athough the changes are pretty good).

Also check out the HRM for your specific part.

We are looking at making the same transition (from ST to Spansion SPI flash chips). We have a couple to test with, but haven't done it yet. I will report back here with the results. If you beat us to it, I would like to hear about how they work for you. Thanks.

we've tested S25FL064 and m25p64 and know they both work (for booting u-boot and using under Linux)
