ESD protection
Several FPGA pins which are directly routed to the FMC connector and they seems no to be protected by any ESD protection.
The base of the transistor T1 which is connected to the FMC connector through a resistor is without ESD protection or EMC protection, so an RF noise can create a spurious activation, in addition ESD discharges can damage the transistor.
