Direct Read/Write of flash from uClinux app

I am trying to use the flash on the development board to store some user settings that remain between boots, but can't figure out how to directly access the flash device. I see that there are fun...

Hi mtmurphy,

There are a bunch of ways to do this. The easiest would probably be to use mtd and do direct

access via the character mode driver (ie -- through the /dev/mtd inode). You would then be

able to read/write and use ioctl for erasing.

A step up from there would be to add jffs2 and just create-read-modify-write a file -- more kernel

config here, but it doesn't get much easier from a programming point-of-view.

Regards,
