  @Anushka2033 We can see that the index file is being downloaded so the issue is the script in the file is failing. I don't use OnionOS app for a long time now so I can only go by my assumptions. I suspect the issue is the script is failing to load the resources due to the certificate error/warning. My first step would be to delete /etc/uhttpd.key and /etc/uhttpd.crt. Then run the commands: uci set uhttpd.defaults.commonname='localhost' uci commit uhttpd service uhttpd restart This should regenerate the certificate files with the correct CN, now see if you can access the OnionOS pages using https.

  @rjtucke It looks like OpenWRT 19.07 uses Python 3.7 Instead of compiling Python from scratch, you can try either: Using the regular Omega2 firmware, add the openwrt-19.07 package repo (https://archive.openwrt.org/releases/19.07.9/packages/mipsel_24kc/packages) to your opkg feeds, and try to install their python. More info on configuring opkg feeds on your device here. Install the openwrt-19.07 (or newer) firmware to your Omega2. Just note that it won't have the customizations that the firmware from Onion has. Let us know how it goes!

  @Antony If you are using Docker, we've released a new version of the onion/omega2-source Docker image that resolves the certificate issue. Pull this latest version of the image, launch a container based on it, and try building again. (More info in this GitHub issue)

  @crispyoz I bought another adapter with ASIX AX88179A chip.

Omega does not see the interface. Maybe this is due to the fact that the adapter has a USB 3.0 interface?

  @Alexandr-Didenko @Lazar-Demin You may have to restart in safe mode, then mount the file system to remove files.

  @Joan-Iglesias as there is no other response, I'll give you my 2c worth, based upon my experience with tensorflow and my separate experience with Omega2. While TensorFlow Lite (TFL) is targeted at low resource devices, ie IoT/Mobile devices, it is likely possible to run on Omega2, however I see a few challenges. 1) The list of supported platforms does not include MIPS, upon which the Oega2 is based. 2) Python3, required by TFL already eceeds Omega2 capacity so you need to extend the storage capacity via USB/SDCard, or use Python Light, but Python Light is "light", so it's missing some funtionality. from what I have seen, some of the missing libraries are written in C/C++ so you'd need to cross-compile this as required. 3) Since TFL has no wheel for MIPS, you'll need to build your own, this is documented on the TFL site but I've not attempted it thus far. I played with TensorFlow on a Pi 4 (B) which is significantly more powerful than an Omega2, it gave me grey hairs. So my general conclusion is that TFL is not well suited to the Omega2, since Omega2 is designed as a low resource, low cost IoT device utilising a Linux like platform.

  @Zonque The reason why you cannot ping or rsync to the Omega2 is that your Mac has no apparent route to the device. Your Mac is most likely routing everything through it's primary network connection on the 10.0.x.x network and that network has no route to the 192.168.x.x network. The simplest method is to connect your Omega2 to the same network as your Mac, that way both devices are on the same subnet and the routing ceases to be an issue. Alternatively you can add a route to yor Mac routing table. First find the name of the interface on Mac that is connected to the Omega2 wifi, use the ifconfig command to see the names, then from the command prompt of your Mac issue this command, replacing the interface name route add -host 192.168.3.1 -interface <name of the interface>

  Yup, it did do that. I finally got in. By the way, I used my iPhone to look at routers on my network and learn some stuff. It helped me find the Omega. Thanks again, folks.

  @magge Thanks for sharing your detailed testing report. I agree with @crispyoz's suggestion to try running your software on stock Onion hardware - this way we can rule out circuit issues. @magge said in Omega2S+ overlay JFFS2 filesystem corruption: Is there a prototyping board I should order when working with this? I tried to google for it but did not get any wiser... There's an Omega2S development board you can use. Or if you would prefer, you can use an Omega2+ and an Expansion Dock. Our distributors have all 3 products in stock and ready to ship.

  @stefanu The answer depends on a number of factors, if you are using the Wap Core wifi driver I have no idea, but its probably 16384. The standard OpenWrt driver has a maximum of of 16384 but suspect you'll get some performance issues long before you hit this volume. f you want to limit the maximum number of connections on your AP you can set it like so: option maxassoc '5'

  @nsmith I'll explain it like this. If I switich on the device and manually set the date and time to July 2nd, 2022 11:22:30 and leave the device running, it will keep the correct time with no need for any network/internet access, so at 15:25;12 on July 2nd 2022 I check the time and find the date and time to be correct. Then I switch the device off. On July 2nd 15:55:12 I switch the device back on. What will the date and time be? The answer is not as you might expect, it is not July 2nd 15:55:12. This is because the device stores the date and time in volatile RAM, so when the power is removed this is lost. When the device starts up it attempts to correct the date and time using a script /etc/init.d/sysfixtime which looks for the latest timestamp on files in /etc, of course if none of these files have changed in months then this doesn't help much. You could run a cron job that touches a file in /etc every X number of minutes/hours, but again if your device is switched off for day you'll still lose a day on the clock. Also touching files in /etc too frequently is not a great idea as it increases wear on the RAM. If your requirement is to simply track the duration of something regardless of whether the date and time are correct you can still do this. For example when your app starts up it might check the date and time (even if it is not correct), then later it could check date & time again and calculate the time difference between these two checks, just not the actual date and time. I hope that helps.
