2 years agoHello.
I will try to create a demo project.
But right now I'm facing a problem as I don't see the link is up after programming the device.
During compilation I got this kind of messages appearing:
Critical Warning(23469): The block fm87_top_bd|mac_subsystem_0|eth_mac|eth_f_0|hip_inst|per_xcvr[0].x_bb_f_ux|x_bb_f_ux_tx did not set the following parameters Critical Warning(23469): The block fm87_top_bd|mac_subsystem_0|eth_mac|eth_f_0|hip_inst|per_xcvr[1].x_bb_f_ux|x_bb_f_ux_tx did not set the following parameters Critical Warning(23469): The block fm87_top_bd|mac_subsystem_0|eth_mac|eth_f_0|hip_inst|per_xcvr[2].x_bb_f_ux|x_bb_f_ux_tx did not set the following parameters Critical Warning(23469): The block fm87_top_bd|mac_subsystem_0|eth_mac|eth_f_0|hip_inst|per_xcvr[3].x_bb_f_ux|x_bb_f_ux_tx did not set the following parameters
Also using signal tap I could see what was going on on status pins of the ethernet IP:
Also i have the next state of QSFPDD control signals:
qsfpdd0_resetl = 1'b1; qsfpdd0_modsell = 1'b0; qsfpdd0_lpmode = 1'b1;
Right now I have no idea of what can be wrong and what can I do to bring the link up.
