Hi,
I have some 100 blank white mifare cards here on my desk. They are untouched have 4B UID and think they are rather new.
I know the keys are default FF FF FF FF FF FF for type A and B.
If I run hf mf mifare it does

Executing command. It may take up to 30 min.
Press the key on the proxmark3 device to abort both proxmark3 and client.

Key not found (lfsr_common_prefix list is null). Nt=267c4affall day long. No matter which card I try.
Its a original board and original antenna - is this happening because of the low voltages?
(hw tune with nothing in field, dip set to on)
# LF antenna: 0.00 V @ 125.00 kHz
# LF antenna: 0.13 V @ 134.00 kHz
# LF optimal: 0.00 V @ 12000.00 kHz
# HF antenna: 8.19 V @ 13.56 MHz
# Your LF antenna is unusable.I left the LF antenna so it is not with me at the moment but its not that powerfull too
I'm running the latest cdc build from the forum -
hw version:
#db# Prox/RFID mark3 RFID instrument

#db# FPGA image built on 2012/ 1/ 6 at 15:27:56Thanks!

You seem to be suffering from the same issue as me - the first two bytes of the parity list are being cleared, for some reason. See page five of http://www.proxmark.org/forum/viewtopic … 7131#p7131 .

I found the bug, it's a subtle one which has pretty nasty side-effects. See http://www.proxmark.org/forum/viewtopic.php?pid=7141#p7141

AFAICT, this affects all platforms, and the CVS-trunk for this feature is currently br0kken.
