Connectivity problem after reimaging Cisco ASA 5525-X to FTD

[nguessankmatt]

Hello team,

I hope your are safe and doing well.

I am facing a real connectivity problem with our ASA 5525-x after reimaging it to FTD version 6.6.4

In fact, we can't ping the management interface and therefore impossible to join the device to FMC.

NB: My FMC is directly connected to FTD in the same subnet.

Need your help.

Can the FTD ping the gateway or FMC? 

Please share the arp table from FTD after trying both.
