Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

Hey guys,

Right now I'm really got sick of my proxmark crashing all the time. Most of this was due a crappy USB implementation (made in the time Jonathan worked on it). We are now 6 years later, with a enormous improvement of features, but still use the old Human Interface Device (HID) protocol to address the proxmark.

So, what did I do. I rewrote the core firmware parts that handles the USB connection. In my tests so far, it is running around 50x times faster and no (workaround) delays are needed anymore. It is more reliable, can handle bigger frames and best of all, it doesn't crash anymore wink

Since I'm using USB-CDC you do not need a driver. Only Windows needs a bit of help detecting the proxmark. M$ decided that Windows needs a .inf file that says... "YES this is indeed a generic uart over USB" ... but then it all works fine.

Since you guys know there is a lot of functionality in the proxmark, it would be good to go over it all and see if it still works with the new USB interface.

So the question is:
- Who is willing to help test the new code, debug if needed, and help fixing (my) mistakes wink

Thanks in advance, best regards,

  Roel

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

I'm proposing to submit my major revision into the SVN and start working from there (any idea how to easily branch in google-code?). It is working already for the most parts. Though I run into some hick-ups of code that was not designed buffer size independent wink

For now, I leave the bootloader code out of the revision. This means you can always flash back the older revision to revive your proxmark again (should anything go wrong). But as it seems for now, I can communicate great with the USB serial port.

Can you tell me what kind of OS you are working on? This could help debugging. I'm running currently Mac OS X 10.8.2, which is basically just FreeBSD if you use the console.

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

Hey All,

I've branched the repository. You can do a checkout and try to compile the new version through:

merged code into default trunk
svn checkout https://proxmark3.googlecode.com/svn/trunk proxmark3 --username ...

or for read-only

merged code into default trunk
svn checkout http://proxmark3.googlecode.com/svn/trunk proxmark3

Please, let me know if you are able to get it compiled/running. Remember, if you want to restore the proxmark to the Trunk version, just hold the button (while replugging the usb cable) and start the flasher program.

Cheers,

  Roel

I can test under BackTrack 5 R3. Bricking one of my Proxmarks is not an issue, I've JTAGed them back to life before.
I can test under Windows 7 and Ubuntu 12.04 if needed.

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

I can test it under 7 but I have firmware r486... is there a fail-proof guide to update firmware ? No need to update bootloader, right ? What about old usb drivers installed ?

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

I tested to compile under Win 7 x64.

With my current setup, I am able to compile the "normal" rev 627 without any errors.
But it fails with this one (everything is fine until it comes to readline...)

I will have a closer look tomorrow.

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

I successfully compiled the cdc branch under Win 7 x64.

Since CDC doesn't require a real driver, but does require a .inf file under Windows. How does this .inf file looks like?

Please re-compile the latest CDC version (changed Vendor/Device identifiers).

I've added the file: driver/proxmark3.inf which should work fine (quickly tested under WindowsXP 32-bit and Windows7 64-bit).

However, it seems that M$ decided that in Windows8 even an ".inf" file should be signed. Who knows, maybe in the future someone will donate a digital signature ".cat" file that signs the proxmark3.inf.

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

Someone using Windows 8 might want to try this

Last night I compiled everything and upgraded my PM no worries at all. I have not had much time to play with it though.

I managed to get the proxmark client to crash by executing these commands in order:

  • h

  • hf

  • hf mf

I didn't need to restart the proxmark. Just the app.

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

Uart CDC/ACM means "virtual com port" ? If it is so, I will surely make a Visual Basic interface for that !!!!!!
Can someone post a compiled version in order for me to test ?
I think I should flash bootloader, fpga and OS, isn't it ?

Sorry for double post

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

0xFFFF: I'll look into the crashing client for windows! Don't know what
is happening. You did supply the correct COM-port as an argument when
you started proxmark3.exe?

ASPER: Yes, CDC/ACM means a virtual serial port (COMx). You can easily
access such port through VB, C#, JAVA or other 4th generation language.
You do not have to flash the bootrom, if you want to re-flash, just hold
button down when plugging the proxmark in the usb port.

I'll adjust the bootloader/flasher program when it works completely and
reliable on all platforms (win/unix/mac).

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

If someone can provide a working FPGA+OS image I will flash and start making a VB software !!! (I know how to communicate using serial ports !!!)

Commands are always the ones described there: http://proxmark3.googlecode.com/svn/trunk/include/usb_cmd.h ?

Parity ? Baud rate ? Stop bits ?

An example of byte sequence to send for example for tune antenna or a nested mifare command ?

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

hi roel ,I come from RadioWar team . I had tested your new firmware on winXP . But failed.

1、As RadioWar said ,after I flash bootrom ,I can't flash anymore 。

I want to reflash an older bootrom such as r627 , It also failed。  The error information looks like “usb_reap: timeout error!” 。

here is a picture。
FluxBB bbcode test

2、about the new “driver”  , it's note work .

Ahhh! Sorry for the confusion. I'm not using Windows at all! I'm using BT5R3.
When you said "...M$ decided that in Windows8 even an ".inf" file should be signed...", I thought someone unfortunate enough to be using Windows 8 might have wanted to try installing the unsigned driver by following the procedure in the link I provided. I don't know if it works or not.
BTW - Personally I think getting drivers signed is a waste of time and money at this point in time. I'd rather buy you a beer for your hard work smile

I have compiled everything and upgraded my PM under BT5R3 and Ubuntu 12.04 successfully.
When using the proxmark client ("./client/proxmark /dev/ttyACM0"), I can crash the client by entering the command "hf mf". I've done 0 investigation. All I did was keep track of the commands I executed in order leading up to the s/w crash.
I'll try to get stuck in to this tonight so I can give more detail as to what went wrong.

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

Did you also flashed the bootrom from the proxmark-cdc version? I should still work according to the old protocol, but I'm not sure it 100% ok. To test the new version you only need to flash the osimage. FPGA and bootrom are not part of the update.

When I have time I'll test if the bootrom code still works with the flash flasher program. In the mean while it would be good to revive your proxmark with the JTAG interface.

yes , I flashed the bootrom from the proxmark-cdc version 。After that (just flashed the bootrom) , it can‘t flash anymore 。

But the proxmark3 is OK . I can use it by the old version . Maybe I can revive it with the JTAG . I’ll try later.

Thanks for your answer 。

thanks xxootest

now works but any command that a i have tried always give me the same error

Waiting for a response from the proxmark...
Don't forget to cancel its operation first by pressing on the button


is like the comunication is going in only one way, when i send any command to the proxmark  it´s look like this has recived the command because the leds works as usual, but the proxmark dosen´t give back to the computer any data.

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

Using Windows7 64 and Windows XP 32 similar problem here:
cpth.png
Just starting it no info shown on screen, neither "Waiting for a response from the proxmark..." but a simple black line.

PM3 is correctly recognized by the system using \driver\proxmark3.inf
deve.png
At first it was on COM21 and I forced it to COM5

If I send commands I can see the PM3 working (Es. sending HW TUNE the green light is on and then, after few seconds, it shuts off) but no on-screen information (no answers from PM3 line); it seems nothing is arriving from PM3.

My PM3 configuration:
Bootloader = r625
FPGA = r627
OS = r635

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

Using OS r635 I was not able to communicate with previous (r627) proxmark3.exe, but I think this is normal.

Just reverted back to OS r627 (holding PM3 button when reconnecting USB cable and during flashing) waiting to reflash another test version smile

Thank you roel ! If a new version will work as expected a windows software will surely come (please send me an example of bytes to send through serial port in order to make PM3 execute commands) !!!

Sorry for double-post but I see that a new r639 is out: is there anyone (RadioWar smile ?) that can compile for windows ? Maybe the "missing header" and "fixed read uart for windows" will solve the problem !

I got it fully working under Windows XP now. No clue why Windows7 is messing up with the communication.

To help you all guys, I just made a fresh compile environment for windows, you can find it here:

Please, make sure you follow the instructions given there.

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

Ok, Windows7 is still buggy (receiving partial frames), but it seems to work at least right now...R641 8)

For building compatible VB software you should look at the content of command frames, just try to figure out how the messages are constructed (look for packed struct UsbCommand). To debug, you can use a Serial Port Monitor (PortMon) or for an x64 system you could use for example the trial version of: http://www.aggsoft.com/serial-port-monitor/download.htm

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

Yes roel, I edited my previous post to show the errors (partial) - I tryed also to "make" inside the fpga folder without any luck.

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

You try to build the FPGA, which is not needed. The FPGA is rarely changed and the new (FPGA) hardware representation is stored in a binary file fpga.bit. There is indeed a makefile in the FPGA folder, but to build it from scratch you need the complete Xilinx SDK (~2gb).

When type "make" in the root folder of the the proxmark repository, it will call the other makefile's (armsrc, client and bootrom) recursively. So if that succeeds you are finished. Just ignore the FPGA folder, you only need if you updated the VHDL code.

BTW, did you do a checkout on the trunk or on the CDC folder.....? Since I actually disabled the (QT) gui in the CDC version, I think you are compiling the wrong version ?:)

The mingw-proxmark.zip instructions show how to download the trunk, but if you want to test my new version you need to replace:

 svn checkout http://proxmark3.googlecode.com/svn/trunk/ proxmark3

with

 svn checkout http://proxmark3.googlecode.com/svn/branches/cdc proxmark3-cdc

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

Well, using this http://proxmark3.googlecode.com/svn/branches/cdc files are compiling (using the root Make file).
testcom.png
So yes, it is working now under Windows 7 64

No luck with http://proxmark3.googlecode.com/svn/trunk/

Do you think that I will always need WT disabled in order for me to compile using my actual environement ?

I will try to log som com traffic right now ! smile Thank you !

EDIT: with the new interface I am not ablt do disconnect the device from my main host to connect it to my virtual station running windows xp (it was working using lib-usb) - maybe this information can be useful.

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

Well, logged data and I think it is that way:

Each sent packet seems to be 527bytes (20F in Hex)

1st 2 bytes represent the command (main command list there: http://proxmark3.googlecode.com/svn/trunk/include/usb_cmd.h)
followed by
525 bytes (parameters and other stuff).

So, for example, if I want to send a "tune" command I must send, over the chosen COM port:
040000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
(this is what I logged)

But, looking at code (I am not good at...) I read:

typedef struct {
    uint32_t    cmd;
    uint32_t    arg[3];
    union {
        uint8_t        asBytes[48];
        uint32_t    asDwords[12];

That means that I have command (2 bytes) + arg (3 bytes) + 48 bytes + 12 bytes = 65 bytes...

I tryed to re-send it using a terminal software but without success... what am I doing wrong ?


EDIT: this is my compiled branch: http://www.sendspace.com/file/4aai4x

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

A progress made !

0004 -> hw tune
0701 -> hw version

So commands must be sent inverted (for ex. in the source code you read 0107 you must send 0701). Some commands are not only 2 bytes, they needs "parameters"; I am studying them !

I can not understand why in the PM3 answer there is lot of "garbage" data... it also seems that some commands are sent also in ascii (with error answer from pm3) and also other commands are sent during operations... but in the interface we only read "intelligible" data.

The proxmark is responding to my serial commands !!!

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

Problem/bug: launching hf mf and sniffing the com port NOTHING is sniffed so the command is not sent through the serial port (absolutely no bytes sent). The same if you try to send hf mf nested or others.

Re: Volunteers for testing new proxmark USB interface (using uart CDC/ACM)

New version always here: svn checkout http://proxmark3.googlecode.com/svn/branches/cdc  ? Should I delete previous version before downlaoding it again ?
