Hi everyone, it’s been awhile since I’ve had the time to play with my Proxmark3, but I was working on it earlier. I have the Proxmark3 from DT and I had followed the full instructions for running the Iceman software and everything. The problem I am having is on HF reads I am getting nothing, as if there is no tag visible to the Proxmark, and LF reads give me communication errors. This is running on a Windows 10 computer and the Com port between the computer and Proxmark is COM6. I have included a screenshot of both reads being tried with known good tags sitting directly on the respective antennas of the Proxmark. I suspect some kind of communication error is occurring between the Proxmark and the computer. The LF side consistently gives me that Graphbuffer error on the first try and then the communication error on the second try. I am just curious if anyone else has ran into anything like this and if anyone has any suggestions on what to do. Possiblity it’s just something right before my eyes that I am missing, but any help is greatly appreciated thanks
So far both an HID formatted card and an EM4100 formatted T5577 card on the LF side, and a card that contains a Mifare chip on the HF side. The EM4100 T5577 card registers on my access control system and the Mifare card is easily read with NFC Tools on my phone and on the computer with an ACR reader.
Thanks everyone for all the help so far, what I did now is try the latest updates, plus another cable, and another computer. I still get the same thing, even says both antennas are unusable when I run hw tune. I got me really curious about that middle board. I haven’t made any physical changes to the Proxmark since I got it. However, here is a picture of the Proxmark as is. I’m not sure if it will help, but this is how it is physically…
That says Dangerous Things to me. In the photo it looks like the side usb port is nearer the top and the button is nearer the HF antenna while on mine the side usb port is between the button and the middle screw. I don’t think that that is relevant but I did find it interesting.
I appreciate all the help and suggestions so far. I actually never got this Proxmark working on any computer to date yet. I had tried to get it working this past fall when I got it, then I went on vacation, and it got put on the back burner as far as projects ever since until now. This could be a slight change in the port position/button and stuff since @amal was waiting on a new shipment at the time when I did order it. A couple of other things I forgot, I did do that swap in the makefile.platform. Also, tried the DT diagnostic card with it now too, and am not getting any LF signal from on an LF Search. It does give me HF signal, however it hasn’t been able to read a HF tag yet tho. Here is a screenshot of the HF tag I was trying to read with it, this is NFC Tools on my phone reading this…
