Yes.
Port fast is only allowed if a BPDU is NOT received;
Check with this command
Show spanning-tree interface g0/24 detail
With portfast configured on the port;
Once a bpdu is received you will see "portfast" disappear from the output of that command.

Subject: STP Question - Port Fast
Salam,
As per Port Fast enable on cisco switches, Does the Spanning tree loop
detection is still in operation, i have read in a BCMSN book CH9 that the
port moves into the blocking state if a loop is ever detected on the port
fast port.
