@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.

@Crazi-Tane "ease of android". If you want to be adventurous you don't go for easy, you push yourself.

Omega doesn't have any hardware to drive a screen, but take a look at the Omega Dash which uses a frame buffer to feed a touch screen.

@Crazi-Tane The short answer is no. Android Things IoT did support some MediaTek stuff but that's now dead and buried. OpenWrt is more advanced and flexible so I'm not sure why you would want to run Android on it, I suspect you are asking because you have a specific app you want to run on an Omega2, right? Maybe there is a suitable solution available.

@Nagarjuna-Reddy you could perhaps use reload_config instead of rebooting but I haven't tried that.

@tjoseph1

When you create anipk there are a few files you need to create, one of which is the control file where you enter things like dependencies and versioning information, plus the supported architecture. Since opkg is used on OpenWrt and OpenWrt supports multiple processor types, features available on one architecture may not be available on another. If there are no architectural dependencies you enter "all" in your control file, otherwise you can list the supported architectures. The mipsel_24kc is the architecture used by the Omega2 series, MIPS architecture. 24K family.

I'm not 100% sure about the intent of "noarch" however when I was first learning to make ipks i missed the architecture entry in my control file and so when I tried to install my package file from the repository the package was not shown. I determined that the cause was that in /etc/opkg.conf I had listed arch mipsel_24kc only. Therefore only packages created for this architecture would be shown, packages with with "all" would also be shown. I added "noarch" to my opkg.conf and my package was then visible. So maybe it is a legacy thing where architecture was not used, or is it a feature to allow you to include packages where no specific architecture has been specified.

The numbers after the architecture are the index, so if you have a package for a range/family of a particular chip you may make that a higher number than the same package set for a specific chip that may be covered by that range. This allows you to create a specific package for a specific chip that may differ from its family in some way that would require a change in your package specific to that chip. The higher the number, the lower in the search tree.

Not a great explanation but I hope it make sense.

@Nagarjuna-Reddy

uci set system.@system[0].ttylogin='1'
uci commit system

Then reboot

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

@Dennis-German If you have an out of date distfeeds.conf is may point to invalid hosts. When you update your firmware to the current release it will update your distfeeds.conf to point to the updated hosts.

@Nagarjuna-Reddy Not that I know of, but I am no authority so maybe some of the engineers have expertise to share.

@tjoseph1 Don't start me on that topic. Why do you think Billy and his babe are donating toilets to the huddled masses? Guilt has a way of gnawing away at your soul.

@tjoseph1 I don't search for ASM, but I might search for "why NeXT failed" and by implication, why we have objective c
