@tjoseph1 and one day it will be as good as OpenWrt! or maybe it will run out of steam.

Thanks @luz I've been meaning to test it for ages but never found the time.

@John-Fjeldberg Factory reset will reenable the AP, you can do this using the reset button on the minidock, here is the process from the docs:

https://docs.onion.io/omega2-docs/factory-reset.html#with-the-reset-button-1

@Crazi-Tane I did respond to this, but seems I did not hit submit. Sorry.

Yes you can run python on Omega2, also micropython may be more appropriate due to its smaller footprint.

Edit /etc/opkg/distfeeds.conf, uncomment lines 2 and 5, then run opkg update.

opkg install micropython will install micropython
opkg install python will install python 2.7.x (light)
opkg install python3 will install python 3.3.x

Python is very popular on Omega devices, so many users can advise you on this. Personally I use C/C++ so I am not the best resource to assist you with python.

@ckielstra this is an oft asked question and usually I would look at the source to get the answer, but the Warp Core wifi module developed by Onion is not open source so we cannot look. I've often wondered if we used the standard OpenWrt Mediatek driver if this feature would be available. On all of my devices (~250) I hide the AP and set a random ssid and password so. Here is an example from one of my devices:

    option ssid 'e8c0ec6432ddbd9-6BC3FD3D'
    option key 'gnkdsjhfksfksgf;isyuf'
    option hidden '1'

@evelina we can't see the entire boot process in your screen shot but clearly you have some file system issues.

Your ongoing loss of files after reboot is unsurprising when I look at the output of your df -hT because it shows your root file system is in /tmp/root which means it will get wiped out when you reboot.

You seem to have 2 separate issues.

1. files lost between boots (see my answer above)
2. cannot access sdcard

In relation to 1, you can likely fix the issue by performing a factory reset. Since you are using an Omega2S I hope you implemented the switch correctly. Otherwise you can run firstboot -y

1. Please check the reference schematic and check you have implemented the design correctly. You can find the schematic here:

https://github.com/OnionIoT/Omega2/blob/master/Schematics/Omega2S-Reference-Schematic.pdf

@apoorvamanjunath please post the output of the command df -hT

@evelina I've never seen this error message but if you google "no support for card's volts" it indicates an issue with your design.

Have you looked at the 2S reference schematics?

@evelina so you're saving stuff to a file system that doesn't exist. Might be the reason that your files are not saved

The second question I asked in my initial response to your query was "....and your boot log". I suspect your sdcard is not being found and I can determine that by looking at your bootlog.

There are two root causes I am suspecting:

1. your firmware does not include the required modules
2. you have an issue with your hardware design. sdcard slots drove me mad last year until finally I realised my gnd was not actually a gnd.

@crispyoz said in onion 2s does not save any data:

@evelina I'd be interested to see the output of df -hT and your boot log.

Also try this from a command prompt.

cd
echo "this is a test" >> mytestfile.txt
cat mytestfile.txt
reboot

After rebooting, type these commands:

cd
cat mytestfile.txt

If the output is "this is a test" then there is no issue with your device, so now look at whatever software you are using and how it is saving files.
