Onion Omega seems to have no wifi

@Boken-Lin Any news on this? Haven't heard from you guys since my confirmation.

Hi @N-Willems, We sent out a package to you around two weeks ago. You should be receiving it in a week or so.

Cheers!

@Boken-Lin Thanks man!

@Boken-Lin
I received the ethernet expansion and matching dock today

@N-Willems Ok, now you will need to re-flash the Omega with the new firmwares. Please take a look at the wik article here: https://wiki.onion.io/Tutorials/Reflash-The-Firmware-With-Ethernet-Expansion. Can you following the steps until Step 6. Then take a screenshot of your browser window? The re-flash process will be slightly different because you will be flashing on a new uboot first. Once you put up a screenshot here we will walk you over the flashing procedures.

Cheers!

@Boken-Lin , I tried, but I can only get to step 4, no httpd.
However, I configured my laptop's networkinterface, and I can ping just fine over the ethernet. And I see a tftpboot command. If I'm not mistaken I only need the correct arguments for it.

Here the output:
(sorry I don't know how to make a codeblock, <pre><code> does not seem to work)

Hi @N-Willems, My mistake. You will first need to use tftp to flash the uboot to the production one first. You can do it by serving a tftp server on your computer, and running the following commands in the current uboot:

setenv ipaddr 192.168.1.1   
setenv serverip 192.168.1.100
tftp 0x80000000 uboot.bin
erase 0x9f000000 +0x10000
cp.b 0x80000000 0x9f000000 0x10000

The uboot binary can be downloaded from: https://s3-us-west-2.amazonaws.com/onion-downloads/openwrt/uboot_for_omega_final.bin. Please make sure that you first disconnect from your Wifi network on your computer, so that the IP address for your computer is assigned properly.

After, you are done with that, you will need to flash the ART partition (which contains Omega WiFi calibration data). You do this by going into the FIrmware re-flash interface, as outlined by the wiki article https://wiki.onion.io/Tutorials/Reflash-The-Firmware-With-Ethernet-Expansion. But, instead of flashing the firmware image, you will click on the link at the bottom of the screen which says ART Update. ART partition binary can be downloaded here: https://s3-us-west-2.amazonaws.com/onion-downloads/openwrt/art_for_omega.bin.

Then, you will need to tell the Omega what it's MAC address is. Reboot again, and enter the uboot prompt, and issue the following command:

setmac 40:A3:6B:C1:06:C5

Finally, you will be flashing the firmware for the Omega, which can be downloaded here: http://repo.onion.io/omega/images/.
