Hi David, please take a look at reserved GPIOs that affect system boot-up:
https://docs.onion.io/omega2-docs/using-gpios.html#important-special-gpios

@Stefan-s As @Douglas-Kryder said, you need to modify your /etc/opkg/distfeeds.conf file and uncomment the following repo:

src/gz reboot_base http://downloads.lede-project.org/snapshots/packages/mipsel_24kc/base

Afterwards, you can issue the following to install the ethtool package:

opkg update
opkg install ethtool

And there you have it!

Hey guys!

The very easy fix to this problem is to issue a updateHostname and your Omega will obtain its proper AP!
Happy hacking!

On the other hand, if you are not using our Docker Image, you will have to run make menuconfig in the build system to select libugpio package to be compiled and then compile it by running make.

In General you will need to have the external library, for instance libugpio, to be compiled by the Build system before it can be dynamically linked to code that you are trying to cross compile. Above all, I strongly recommend basing your BUild system on our GitHub source repo since it is preconfigured to include the Onion software repo and to build all the libraries that are included on the Omega.

@Tim-DeBenedictis @James-Tate it's possible that you guys are overwriting the .config file with the scripts/feeds script. Please review the earlier post where the overwriting problem is described: http://community.onion.io/topic/2755/wifi-not-working-after-building-customized-image/30

@Aj-Blosser It seems that you are running not on the latest firmware and that is why you cannot setup an AP from the console. I recommend you to update your firmware to the latest and perform the AP settings again from the console. It will work, please see the picture below, I used the same name as you've provided and as you can see it works!

Happy Hacking

@peterh-peterh @peanut Here is the procedure on how to enable HTTPs for uhttpd and generate self-signed certificate.

1. From your command line issue the following commands:

opkg update
opkg install px5g-standalone libustream-openssl

1. Restart the uhttpd service:

/etc/init.d/uhttpd restart

1. When you restart uhttpd service, it generates RSA private key and selfsigned certificate, here is the output that I've got after restarting uhttpd:

# /etc/init.d/uhttpd restart
4+0 records in
4+0 records out
Generating RSA private key, 2048 bit long modulus
Generating selfsigned certificate with subject 'C=ZZ,ST=Somewhere,L=Unknown,O=LEDEd1d8b179,CN=LEDE,' and validity 20180417162546-20200416162546

1. Now you can navigate to your browser and type: https://192.168.3.1 or https://omega-XXXX.local ( where XXXX are the last digits of your MAC address). Here is my screenshot:
   

Enjoy and Happy Hacking

@Unbioctian take a look at /usr/lib where the library shared objects are kept and /usr/include where the header files are kept. You'd notice some library objects do not have corresponded header files. The i2c C library is available for you and is called libonioni2c. The source code can be found in our GitHub repo. For more info on compiling C/C++ on the Omega please refer to our official documentation and i2c C Library

@Arek-Z Thanks for sharing this great solution!

Only the binary is available for this mt76x8 driver and it is actually compiled for 4.4.46 Kernel version. On the current firmware (b160), the mt76x8 is located under the /lib/modules/4.4.46.

As you can see in the package makefile the install deirectory is based on $(LINUX_VERSION) variable. I would suggest trying your luck with modifying this installation path.

There is actually a simplier way to flash the bootloader: by using the Bootloader web recovery mode. Please follow the instructions provided in our docs on how to flash the firmware via web recovery mode but when you get to the 192.168.8.8, you'll be presented with the page where you need to load the firmware or load a UBoot file.

You'll want to click uBoot Update and load the bootloader binary. This will start the bootloader installation process. You can get the officail Omega2 binaries from our us.

If you flash a broken bootloader, you need to physically desolder and reprogram the flash memory.

If you modify the bootloader and/or make any physical modifications (e.g. remove the flash and etc), Onion Corporation is not responsible for any damage to your device and the warranty will be voided. Proceed at your own risk.

To change the documentation, we welcome pull requests to our Onion-Docs repo on GitHub to make changes that will benefit our entire community. Docs.onion.io is generated form this repo.

@Fabian-Nydegger-0 You can scan the WiFi networks using a single ubus command:

ubus call onion wifi-scan "{'device':'ra0'}"

The wifisetup (not setup wizard as you mentioned) gets you through the process of connecting to available AP's. Also, wifisetup utility is an open source program that you can take a look in Our GitHub Repo

@Andrew-Moore said in From "Cross-Compiling for the Omega" I cannot successfully build the gpioRead example:

the instructions did not say to wget the Makefile and it was not preselected in the .config

It was never mentioned that you have to wget the makefile. If you followed this example, you are cloning the GitHub repo to your build system that already contains makefile, xComile.sh and the source code. The tutorial guides you through every step from building the source image and cross-compiling the program.
