Hi everyone,
I have an omega 2 + and I'm trying to extend the RAM memory.
After the USB is mounted to "/mnt/sda1" (i checked and there's no directory such as "/tmp/mounts/") I typed "dd if=/dev/zero of=/mnt/sda1/swap.page bs=1M count=256" and this is what I got:
root@Omega-6E16:~# ls /mnt
mtdblock7 sda1
root@Omega-6E16:~# dd if=/dev/zero of=/mnt/sda1/swap.page bs=1M count=256
dd: can't open '/mnt/sda1/swap.page': Read-only file system
Any ideas?
Thank you for your help.
@crispyoz Thank you for your prompt reply and your help. At the end it was a problem of the customized PCB, it wasn't well rooted.
Hi everyone!
I'm trying to use USB storage, so I plug in de USB device and according to the documentation it should be automatically mounted and located in /mnt/ by default, but I can't see the USB storage there (sda1)
root@Omega-6E16:~# ls /mnt/
mtdblock7
I couldn't find it in /dev :
root@Omega-6E16:~# ls /dev/

The mounting configuration seems to be fine:
root@Omega-6E16:~# vi /etc/config/fstab
config global
option anon_swap '0'
option auto_swap '1'
option auto_mount '1'
option delay_root '5'
option check_fs '0'
option anon_mount '1'
Can you help me, please?
@crispyoz I already did it but didn't work, got the same message
