@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 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.

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 :

The mounting configuration seems to be fine:

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

Hi all, I'm trying to install the pc-ble-driver-py library on my Onion Omega 2+
I have already installed full version of python3 and pip3.

When I runned "pip install pc-ble-driver-py" I got this:

I checked the memory and it should have enough:

I have tried to download the .tar.gz and install it maually by typing "python3 setup.py build ":

I installed the module

root@Omega-6E16:~/pc-ble-driver-py-0.15.0# pip3 install scikit-build

And I tried again with "python3 setup.py build " and this is what I got:

Problem with the CMake installation, aborting build. CMake executable is cmake

So then when I tried to install cmake this error showed up:

Any suggestions about installing it with pip or manually?
