Can somebody help me with providing some guidance on how to provide more information and/or make the necessary modifications to the source code for supporting this version of the device?
I feel seriously misled. I trusted the statement on the openWRT website (install via web-interface), and it influenced my decision to purchase this device.
Where do you live? Maybe I can send you the device to install openWRT on it?
The onus of checking the initial flashing procedure and support state of the device port is on you, preferably before purchasing a device. Ideally all devices would have a verbose device page in the wiki, laying out the details - but that is not a given and not enforced/ enforceable, what is usually enforced is having these details in the commit message adding support for the device (such as the one listed in the very first post of this thread).
If you don't like OpenWrt, you are free to request a refund for the licensing costs of your OpenWrt copy from your distributor.
Well it looks like the Board changed also the lettering with the v1.2 because the github discription doesn’t match with my board. I’m stuck at the solder bridge and don’t really know where to look.
