maemo.org - Talk - Campact Flash Card Reader and Nokia 770 / 800

With the 770 yes, you probably (99.9%+) can. Use a USB power injector (http://tabletblog.com/2006/01/usb-power-injector-2.html, for example), use flasher to enable USB host mode (from http://maemo.org/downloads/d3.php -- you need a Linux system to do this, I recommend the Damn Small Linux live CD). The instructions are here: http://maemo.org/community/wiki/easy...ost_hub_setup/ (read them with care).
Finally, connect the card reader, insert the card, and THEN mount the card reader on the 770 as you would under any other Linux:

Code:

gainroot

mkdir /home/user/CF

mount -t vfat /dev/sda1 /home/user/CF

These commands require X-Term (osso-xterm) and the gainroot script (becomeroot) and need to be executed in X-Term. After the first time, you only need to execute:

Code:

gainroot

mount -t vfat /dev/sda1 /home/user/CF

The card can then be browsed using the file manager / FTP client / ... (just look for the directory called CF on the left hand side). Before removing the card from the reader, or disconnecting the reader, open X-Term and execute:

Code:

gainroot

umount /home/user/CF

NB: Another way of enabling USB host mode is described here: http://www.internettablettalk.com/fo...&highlight=usb (in one of the posts by fanoush). I never used this method though.

With the N800, host mode (currently) doesn't work, so no you cannot do any of this, sorry. On my 770, I have used the above method with USB pen drives (1GB and 4GB), a 40GB hard disk and a CD-ROM drive (no disc though) -- the last two with an IDE to USB convertor -- so it *should* work with anything you might care to throw at it, including a compact flash card reader.

HTH,
Dre
