[U-Boot-Users] "Question on expansion of Flash"
Hi All,
I am working on walnut board which is having 4MB flash . Currently it is working fine. We are trying to place 8MB Flash to accomidate some extra software components. Now my question is , what are the necessary modifications to the existing u-boot files to make it work with 8MB flash insted of 4MB flash?
Can anyone help me in this regard?
Thanks in Advance, Nagi Reddy

If U-Boot is already know about the new 8MB flash then the new 8MB Flash will be detected seamlessly. Otherwise, you have modify the U-Boot's board specific flash detecting part by adding the Manufacture id, Protect id and size info.
See: ./board/walnut405/flash.c -> flash_get_size()
HTH :)

Adapt the flash configuration in the board config file and the flash driver for your board.
