>Make sure you have those config options (linked in my previous email) setup correctly for your target, as well as having the bitstream loaded and it should setup the mac address when u-boot probes the ethernet device.
Ok I understand the flow. 
Bitstream is loaded before u-boot for sure.
Since I'm using the u-boot from meta-xilinx, I should have the config options set correctly right ?
The only things I have to do actually is to attach correctly a PS i2c to EMIO, then to pin N18 and N17 on zybo ?
I will check this part tonigh !

>>>If you need FSBL then you will need meta-xilinx-tools, or you will need to do it manually.
>> Understood. So what FSBL is for ?

>FSBL is supported by Xilinx, you can spam their support if you have issues :).
Right for sure ;p
