    Well, for example, the openwrt current version for pine 64 does not support hdmi. What I did is similar to what is explained in this link

    Does a 'router like' board need HDMI? Well different people, different opinions on that. Problem is when you start to mix up those things, openwrt may have some needs to for a kernel which 'we' don't care (I'm not really familiar with openWRT). How do you ensure that your device gets regular updates (kernel and userspace side) when you've a combination whit doesn't fit to both distributions? This may need additional work to keep your device updated. For me, such router/network boards should run with a (patched) mainline/vanilla kernel or at least with a kernel which isn't EOL (the only device which doesn't get regular updates in my home is the outdated iPad and the android phone, sony decided that my phone isn't worth to get updates a few months after I bought it :angry:). 

    I am just giving an example, of how when I mixed them something that did not work is now working. Also, I could find the battery level which was not available when I used pure openwrt. The main kernel is openwrt now, so when I write on the terminal is appears as openwrt. 
    And yes, my software is built on openwrt.  Another advantage is that they have the LUCI interface ready which is a GUI of configuring the router. That is a problem. I agree mixing between two different OS is not a good idea. But I will try and see if I did the opposite,

    don't sound sane to me.. :P Where do you start to mix things? There are so many possibilities that things can go wrong and support might be a nightmare if you don't describe exactly what you did..

    When I did that, I now can use openwrt on the board and still use the screen instead of the serial console.  Openwrt has a lot of advanced networking packages that I need to use. The point is that I started the software development part before choosing the hardware. Now I am stuck :(

    So, I already tried to use the WiFi module.  The problem is that I am trying to use openwrt with the board. I did a mix between Armbian and openwrt and used with the board which worked fine, but still can not recognize the WiFi module.  I am trying to make the Armbian the main and openwrt on it instead to see what will happen.

    I need to connect three USB Wifi modules. That is all I need. I tried to find a solution for that but the only one I could think of is to add an extra USB port. It seems this idea will not work.  Is it possible to add a WiFi module on the Pi-2 or Eurler Buses on the board directly? Can we use a USB to UART convert to connect another USB port?

    Thanks all, that was a very helpful discussion. I got the Pine64 and I am trying to use it. However, it has only two USB ports and I need at least 3 ports. Is there a way I can add a USB port on the Pi-2 Or Euler Buses on the board?

    Thanks for your replies.

     

    Essentially, am trying to build a travel router. So the crypto engine shall be indeed usable with OpenVPN & Snort for example. What boards are there with usable crypto engines then? 

     

    Regarding the 3g/4g/lte thing, I was advised to just forget about it and use a usb modem for that since it differs from a region to the other (bandwidth restrictions). So we can put that aside. 

     

    What is hard to find is a board that has 

    - 1 usb  port (for usb modem)

    - crypto engine

    - 1 gb ram 

    - Onboard storage emmc or nand

    - 1gb Ethernet 

    - 2on board wifi modules - or 1 and 1 extra usb (for usb wifi) 

    - PMU (for battery management) (and charge port)

    - On/OFF power switch 

    - very small board 90mmx13mm at max 

    - Cost should be under 30usd

    I don't know if this the right place to post this question. I am looking for a board that fits what I need. I have been looking and could not find everything I need in one board. I thought of asking here maybe someone can suggest something. So here are the specifications I am looking for:

    1- CPU: has a crypto engine/ Security system. Almost all Allwinner Axx and Hx have crypto engines. 

    2-  wireless connectivity Has all or most of the following: WiFi 2.4G, 5GHz and 3G/4G Module if possible.

    3- Network connectivity: Has 1000 Mbps Ethernet.

    4- USB : At least one A-type USB.

     

    Thanks

    Thanks a lot for your reply. I could not find anything about the battery. This is a list of the folders in the path /sys/class/ the power_supply is empty.  Do you have any hints on how I should proceed?

    Measuring Batter level on Lime2

    in Beginners

    Posted

    Hi, I started using Lime2 recently. I am using Openwrt with Lime2. I am powering the board using LiPo battery. I could not find a way to find the battery level. I use SSH to communicate with the board. Is there any script or way to find the battery level through SSH. Help please.
