[U-Boot-Users] P30 Flash drivers in u-bbot

[Jayasri Sangu]

Hi ,

    We are using u-boot as bootloader for our mpc8260 board. At present the board uses  28F320C3 intel flash and it works fine.

Now we want to upgrade the flash to Intel P30 strata flash. Does U-boot have already drivers for that or do we need to write driver to support new flash.

Thanks
Sri

The U-Boot common CFI flash driver supports CFI compliant flash devices. And 
yes, the Intel P30 strata flash is know to be working with this driver.

Please check yourself - is the P30 CFI conforming? Is  it  listed  in
include/flash.h ?

Hi Stefan,

     I found strataflash driver in u-boot which is cfi compliant. Can I use that?
I tested the strataflash driver on other CFI compliant flash and it works, but the flash is listed in include/flash.h.

The P30 flash is not listed in include/flash.h. 

Thanks
Sri

I was not talking about the strataflash driver which is available in multiple 
board directories. Please take a look at the common CFI flash driver 
(drivers/cfi_flash.c). You can "clone" it's configuration for example from 
the p3p440 board (include/configs/p3p440.h). Then you can drop your board 
specific strataflash driver.

And please stop top-posting!
