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).

 

http://docs.blackfin.uclinux.org/doku.php?id=bootloaders:bootrom

 

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)
