Latest patches to build firmware 0.5.3-6ea9-dirty
by Petrus Du Toit 05 Dec '14

05 Dec '14

Hi, I have been trying to follow the steps in the post with subject "firmware 0.5.3-6ea9-dirty Ubuntu howto" on 2014-11-11 by pkix as I am having the same problem where simtrace just stops tracing some time after displaying garbage APDUs. None of attachement links in this post work (Error 404) so I cannot download the patches or the firmware. Please could someone tell me where to find the latest patches (unofficial, official) for the firmware and simtrace source. I have been trying to look on the mailing list but there are only archives for November 2014. Thank you in advance.

Incomplete trace (due to high-speed SIM?)

firmware 0.5.3-6ea9-dirty Ubuntu howto
by pkix 11 Nov '14

11 Nov '14

Problem: Latest official simtrace firmware v0.5 fails to trace some smart cards. The APDU output is meaningless and tracing stops after displaying few garbage APDUs. There is unofficial firmware "0.5.3-6ea9-dirty" which tries to fix the problem. Here are step-by-step instructions how to try out firmware "0.5.3-6ea9-dirty". Updating simtrace firmware: sudo apt-get install dfu-util wget http://lists.osmocom.org/pipermail/simtrace/attachments/20140624/a17d1070/a… sudo dfu-util -d 16c0:0762 -a0 -D ./attachment-0001.bin -R Now connect debug interface and press "reset" button on simtrace. You should see: sudo cu -l /dev/ttyUSB0 -s 115200 [000002] Version 0.5.3-6ea9-dirty compiled 20140624-112040 by min@Wolfgang Patching simtrace host software: sudo apt-get install libusb-1.0-0-dev wget https://launchpad.net/~osmobuntu/+archive/ubuntu/ppa/+files/libosmocore-dev… wget https://launchpad.net/~osmobuntu/+archive/ubuntu/ppa/+files/libosmocore_0.5… sudo dpkg -i libosmocore_0.5.3+git1-1_amd64.deb sudo dpkg -i libosmocore-dev_0.5.3+git1-1_amd64.deb git clone git://git.osmocom.org/simtrace cd simtrace git checkout e179a32048e cd host wget http://lists.osmocom.org/pipermail/simtrace/attachments/20141023/4e37cb7d/a… patch -p2 < attachment.bin make sudo ./simtrace Report success or failure to mxu(a)sanjole.com .

Does SIMtrace work with 3G/4G USIM?
by Shafiul Alam 10 Nov '14

Dear Correspondence, For my academic research, I am interested on the SIMTrace product. I need to know about the transmitted data between 3G/4G USIM and the ME. Does SIMtrace help me to know that?

sniffing hangs / too fast sim? / parsing problem?
by Lukas Kuzmiak 24 Oct '14

24 Oct '14

Hey guys, this problem has been around for ages (from my perspective) .. and I don't seem to understand if it's a SW issue or a HW issue. I start the ./simtrace .. and then insert the SIM into the phone (or vice versa), boot up the phone and start sniffing (log below). It works for a second or two and then the stuff get broken into weird parts .. I could probably fix that in apdu_split.c but the other issue is that it stops sniffing completely at that point for some reason. Any idea why that happens? Thanks!

MITM / USB CCID card reader
by Stathis mozbery se lew 22 Jul '14

22 Jul '14

Dear list, I would like to ask the currently status of MITM implementation on SIMtrace? On some prior postings on the list I found about some previous works on it: git://git.gnumonks.org/at91work.git https://github.com/zwizwa/at91work/tree/apdu_phone I am also intresting in turning the simtrace into a USB CCID based smart card reader in order to use http://openbsc.osmocom.org/trac/wiki/osmo-sim-auth with the SIMtrace. In the usb-device-ccid-project directory when I am trying to use "make" i am getting the following error: user@ubuntu:~/at91work/usb-device-ccid-project$ make cc -g -Os -I../at91lib/boards/simtrace -I../at91lib/peripherals -I../at91lib/components -I../at91lib -Dat91sam7s128 -D__ASSEMBLY__ -Dflash_dfu -c -o obj/flash_dfu_board_cstartup.o ../at91lib/boards/simtrace/board_cstartup.S ../at91lib/boards/simtrace/board_cstartup.S: Assembler messages: ../at91lib/boards/simtrace/board_cstartup.S:55: Error: unknown pseudo-op: `.arm' ../at91lib/boards/simtrace/board_cstartup.S:137: Error: no such instruction: `ldr r4,=_sstack' ../at91lib/boards/simtrace/board_cstartup.S:138: Error: too many memory references for `mov' ../at91lib/boards/simtrace/board_cstartup.S:139: Error: no such instruction: `ldr r0,=LowLevelInit' ../at91lib/boards/simtrace/board_cstartup.S:140: Error: too many memory references for `mov' ../at91lib/boards/simtrace/board_cstartup.S:141: Error: no such instruction: `bx r0' ../at91lib/boards/simtrace/board_cstartup.S:144: Error: no such instruction: `ldr r0,=_efixed' ../at91lib/boards/simtrace/board_cstartup.S:145: Error: no such instruction: `ldr r1,=_srelocate' ../at91lib/boards/simtrace/board_cstartup.S:146: Error: no such instruction: `ldr r2,=_erelocate' ../at91lib/boards/simtrace/board_cstartup.S:148: Error: too many memory references for `cmp' ../at91lib/boards/simtrace/board_cstartup.S:149: Error: no such instruction: `ldrcc r3,[r0],' ../at91lib/boards/simtrace/board_cstartup.S:150: Error: no such instruction: `strcc r3,[r1],' ../at91lib/boards/simtrace/board_cstartup.S:151: Error: no such instruction: `bcc 1b' ../at91lib/boards/simtrace/board_cstartup.S:154: Error: no such instruction: `ldr r0,=_szero' ../at91lib/boards/simtrace/board_cstartup.S:155: Error: no such instruction: `ldr r1,=_ezero' ../at91lib/boards/simtrace/board_cstartup.S:156: Error: expecting operand after ','; got nothing ../at91lib/boards/simtrace/board_cstartup.S:158: Error: too many memory references for `cmp' ../at91lib/boards/simtrace/board_cstartup.S:159: Error: no such instruction: `strcc r2,[r0],' ../at91lib/boards/simtrace/board_cstartup.S:160: Error: no such instruction: `bcc 1b' ../at91lib/boards/simtrace/board_cstartup.S:176: Error: no such instruction: `ldr r0,=main' ../at91lib/boards/simtrace/board_cstartup.S:177: Error: too many memory references for `mov' ../at91lib/boards/simtrace/board_cstartup.S:178: Error: no such instruction: `bx r0' ../at91lib/boards/simtrace/board_cstartup.S:182: Error: no such instruction: `b 1b' make: *** [obj/flash_dfu_board_cstartup.o] Error 1 Thanks for any replies and for your time With Best regards Stathis

Fast SIM cards loosing bytes
by Dean Chester 24 Jun '14

24 Jun '14

Hi, I see earlier in the archives that reducing the buffer size in the firmware will resolve this. Hasn't this already been done though in new releases of the firmware? As I have pulled the latest version from the openpcd git repo and built it. If not what have people reduced the buffer size to? And has it had any fixes? Sent from my iPad
