Tips to build a router with BPI-R4-8P model

Hi folks,

I bought a BPI-R4-8P (still needs to arrive), and I’m wondering how can I put OpenWrt on it.

I saw plenty of discussions about 4GB x 8GB RAM, also there is a special image for POE, which this model has, special image for 2.5GbE, which this model also has, and beside that, I will use a BE14 card, and also there are specific problems with the tx power.

Do you have more details about how to OpenWrt in this model that has such different features than the default one?
