Re: [Gumstix-users] Ash: Write Images to Flash

[James <ang...@gm...>]

Hi Ash,

Although we are moving to UBIFS for the new branch,
would you mind update the script in the website
http://www.gumstix.org/how-to/70-writing-images-to-flash.html

to amend the portion regarding the JFFS2 so as to have a closure for future
reference and new users.

A reference to Steve's page for writing UBI format will be very helpful too.

No obligation.

Cheers~!

James.
