Even if you dont't use U-Boot as bootloader, I'm sure that the documentation in will interest you.

Asunto: MTD Flash Howto ?

    I need to put together a filesystem driver for the flash in the Pico E-12.
    I think I have a pretty good grasp of what I need of the FileSystem end of things.

    But I am less certain of the peices needed to get from the flash to the block driver that I assume underly's the FileSystem.
    I have enabled MTD, and configured a starting address and size.
    I got a signon banner. How can I tell if it has really found my flash and if it actually knows the type of flash it found - in my 
    instance Spansion S29GL512N.

    I have found some documentation covering details, I think I am more interested in something that gives a more zoomed out view.

    Is anyone aware of a relevant howto ? Maybe some web pages on the end-end process of going from flash devices to filesystems over flash ?
