Hi!
I recently acquired my Nokia N810, but have been having problems with my memory card. Since the first day, the mini-sd memory card has not been showing on my device. The current is the 3rd mini-sd card I try, and none seems to be recognized. I have searched on the forums but did not find this specific problem, so I am asking the expert community.

My device is running OS2008 4.2.30-2 with a 2GB Sandisk mini-sd card (actually, micro-sd with a mini-sd adapter).

I tried mounting the mmc card from the command line but it failed... actually, no mmcblk device exist.

This is the output from ls on /dev:

Code:

I was expecting to see a mmcblk device from which to mount.

This is the output from cat /proc/partitions:

Code:
[1|root@Nokia-N810-23-14|~]cat /proc/partitions 
major minor  #blocks  name

  31     0        128 mtdblock0
  31     1        384 mtdblock1
  31     2       2048 mtdblock2
  31     3       4096 mtdblock3
  31     4     255488 mtdblock4
Again, no mmc present.

Finally, the output from mount:

Code:
[1|root@Nokia-N810-23-14|~]mount
rootfs on / type rootfs (rw)
/dev/root on /mnt/initfs type jffs2 (ro)
none on /mnt/initfs/proc type proc (rw)
none on /mnt/initfs/sys type sysfs (rw)
none on /mnt/initfs/tmp type tmpfs (rw)
/dev/mtdblock4 on / type jffs2 (rw,rpsize=1024,rpuid=0,rpuid=30000)
none on /tmp type tmpfs (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
none on /dev type tmpfs (rw)
devpts on /dev/pts type devpts (rw)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
I thought that one of the mmc was mounted automatically, as it is the internal memory card... Every time I connect the usb cable is shows: Unable to connect via USB. No memory card inserted.

Am I missing something?? Or is my device damaged??

What type of the partitions created on the mmc?

Have you checked (by using lsmod) to see if the module for the mmc partitions loaded?

It looks like you need to do insmod to load the appropriate modules for partitions on the mmc, i.e. ext2 or ext2!

I don't think you have fat or vfat on the mmc.
