The internal storage and the SD card are not exported as mass storage, so you can't mount it from a linux pc.

The internal storage is exported via MTP, see also https://together.jolla.com/question/282/usb-file-transfer-support-for-mac-os-x/ it has some infos for Linux how to access it.

MTP is unfortunately not mentioned in Jolla's guide. Internal memory works now.

Is there a solution how to access the sdcard? I can see only folders "Phone Memory" and "Playlists" when accessing the device using mtp.

What I did was enable developer mode from my Jolla, SSH connection to the phone, use the "devel-su" command to gain root access (same passwd as the "nemo" user that you set from enabling the ssh connection!)

And then I created a symlink to "/mnt/sdcard" into the "/home/nemo" (which is shown at USB plug in with windows) and voilá -- I can access the sdcard.

How to mount it directly, "don't ask me", but that's how I solved it for me. ;)

Note that /mnt/sdcard is a link to /data/sdcard and you can view it e.g. via WinSCP once you set up the SSH connection.

Yes, that works of course. I was expecting Jolla to expose the SD card content using MTP protocol.

@hana You can use a graphical explorer like WinSCP or just PuTTy. Note that to use SSH you need to enable Developer mode on Jolla and setup the password in Developer mode settings. You will be able to login as user "nemo" (and the password you set).

Nux ( 2013-12-29 22:59:39 +0200 )edit

@Nux I tried PuTTy before but I don't know how to connect to Jolla, I tried to connect to the IP address that is shown in Jolla's developer settings but nothing happens. I will take a look at WinSCP next.

hana ( 2013-12-29 23:02:39 +0200 )edit

OK now I got WinSCP working, I need to edit Windows network settings for "Remote NDIS..." to set an IP address manually for the machine (I chose IP address close to Jolla's address). So now it can connect to Jolla's IP address and it seems to work fine.
