Unable to mount external sd card in rcS

Lucas Malor · 07-28-2014, 03:08 PM

I'm trying to backup the internal sd card using an external one, but I can't mount the external sd. I added to rcS, before

PHP Code:


			
/bin/dbus-uuidgen > /var/lib/dbus/machine-id

the following command

PHP Code:


			
mount /dev/mmcblk1p1 /mnt/sd

but I get this error:

PHP Code:


			
mount: mounting /dev/mmcblk1p1 on /mnt/sd failed: No such file or directory

After booting, if I connect to Kobo via ssh and do the command manually, it works. This is very strange. Someone has any idea?

I am only guessing. When you try to mount, the sd is not yet recognized by the system. You could trying make the script wasting some time before it tries to mount. Or maybe you could use a loop until the mount was successful, with a limited number of trials (in case this does not work).

Nope, I waited 70 second but nothing. It seems that external sd is unavailable until nickel starts.

I know from using Kobo Start Menu, that sd is available (and is automatically mounted via usr/local/Kobo/udev/sd) without nickel.

And "mount -o remount,rw /mnt/sd", works. There is a -t in there someplace as well, if I recall correctly. Don't know why mount prefers the mount point over the device name.

I'd disagree with your conclusion. When I use AdvBoot to start koreader, nickel is never started and I can read ebooks on the external uSD card.
