VoCore MicroSD Slot

Sat Jul 04, 2020 2:34 pm

Dear all,

I have a VoCore2 + USB & MicroSD Slot, and trying to mount a micro sd card.
With
Code: Select all
 fidsk -l
command, I see:

Disk /dev/mmcblk0: 119.1 GiB, 127865454592 bytes, 249737216 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes


I can also format the card into ext4 by using the
Code: Select all
mkfs.ext4 /dev/mmcblk0
command,
all works fine.

Now when I enter
Code: Select all
mount /dev/mmcblk0p1 /overlay
, I can't come past this error:
mount: mounting /dev/mmcblk0p1 on /overlay failed: Invalid argument


Also tried to mount on other folders as /root/mnt, but with the same error.
Is it a problem of the large SD card size?

I do not have that big SD card for test :) maybe you can try a small one?
and make sure the firmware has ext4 driver installed, sometimes if no driver or broken it will show that error.

Thanks Vonger,
the ext4 driver was missing. I somehow thought I already had it :roll:
Keep up the good work!
