Re: [ECOS] Problems with JFFS2 mount

["Manoj Abraham" <manojkabraham at india dot com>]

Hello,

        I have unlocked the flash and tried. The file system mount is succeeded but erasing my entire flash including redboot data,fis dir.. etc. It writes  0x00800080 to all flash locations. Whether the mount process will scan entire flash or only the image area?

Thanks

Manoj K Abraham
