get mtd name and manufacturer from high level app

get mtd name and manufacturer from high level app

[Salvatore Frizzoli - IMS Italy]

Hi all,

I am working on an application under a uClinux kernel.
This application would read name, manufacturer and id of the mtd flash 
device.
I have seen that it is not possible to do this by ioctl, so I don't know 
how to do.
I have also seen the get_mtd_device function, but i cannot know how to 
fill the
mtd_info struct that get_mtd_device takes as input parameter.

Is there a way to get theese infos similar to ioctl?

Thank you all.
Bye.
Salvatore

Take a look at the mtdinfo utility in mtd-utils/ubi-utils. It reads most
of the data from sysfs.

Manufecturer ID is not available though, and you need to teach the
kernel to export it.

Look inside of mtdinfo to find out how it does things. You can also
extend it and send patches.
