We're working with an ODM vendor in China to develop a new hardware device. The hardware is based on the Mediatek MT7622 SoC (already supported in OpenWRT), with a Realtek 2.5GbE PHY and MTK Wi-Fi 6. We have limited knowledge about the details of the hardware, and frankly we don't even know the right questions to ask. The ODM vendor is willing and able to help with hardware matters, but has little software expertise. We have a relationship with MTK so can request the necessary SDKs if needed.
The ODM has already provided a more or less working demo firmware based on an old LEDE version (probably based on a SDK from Mediatek), but they can't provide the sources. We also have a development device locally. From this demo firmware we can extract the Device Tree and other basic information about the hardware.
The ask here is for a contractor to help develop an OpenWrt based firmware to support the hardware provided by the ODM.
