new driver

[Dominik Schröder]

Hello

 

I want to design a new driver for the At25DF641 SPI flash. I think the
needed protocol is a bit like the protocol of the At45 Flash.

How do I start implementing a new driver for this device?

Eventually somebody can give me a short tutorial.

 

Best regards

 

Dominik Schröder

Hi!

Copy the driver from another best matching device and modify it as
needed. If you later see many parallels, that try to unify or merge the
drivers. And keep an eye on the entry functions. They should not be chip
specific or if the chip has some more functionality than the standard
flash drivers provide, provide them as an extra.

Best regards,
Ulrich
