    This is entire session of ATR.
  • Smartcard ATR by Sigrok with Saleae Logic 16

    2019-03-01T23:14:16Z via Identi.ca Web To: Public CC: Followers

    This is a pulseview window of sigrok.
    I needed to have a "look" at these signals to debug my smartcard reader.

    • D0 line is power supply of +3V3.
    • D1 line is I/O.
    • D2 line is RST.
    • D3 line is CLK.
    We can see that after RST asserted, smartcard emits ATR string to I/O.

  • My smartcard reader

    I gave up using smartcard reader (of proprietary firmware).
    I start my own firmware implementation.
    Today, I successfully got ATR of OpenPGP card V3.3.

    I was asked about CERN's license(s) draft.  I was not pleased about the scope of its license(s) addressed in the preface.  For me, it seemed that It only focused on mutual benefit of collaboration.

    I wrote that my particular reason why I put my design free is to ensure reproducibility of my design for user's computing freedom (to protect his own privacy).

    Then, its preface is now:
    CERN has developed this license to promote collaboration among hardware
    designers and to provide a legal tool which supports the freedom to use,
    study, modify, share and distribute hardware designs and products based
    on those designs.
    Great improvement!

    This is the mass production version of FST-01SZ.
    It is available before the Chinese New Year.

    For some reason, pumpa on Debian testing doesn't work (segfaults).
    In this situation, I was unable post for FOSDEM.
    Now, I'm writing this message, enabling JavaScript.

    Maybe it just needs a rebuild. Did you report a bug?


    BTW, you could try Dianara too 😆

  • Gnuk 1.2.11

    2018-11-12T06:36:41Z via Pumpa To: Public CC: Followers

    Gnuk 1.2.11 is out.

    It has a FST-01SZ support, which has ACK button.
  • FST-01SZ with ZL271 (only) and magnet

    2018-10-01T08:45:10Z via Pumpa To: Public CC: Followers

    Perhaps, this will be my use case for FST-01SZ.

    I mean, I don't put another enclosure to ZL271 (the metal one). It's easier when something goes wrong and I need to connect SWD debugger.

    A magnet which I use in the previous post is too strong for direct ZL271.  It requires more power to remove off, which is inconvenient.

  • FST-01SZ with ZL271 and metal enclosure, with magnet

    2018-10-01T07:41:15Z via Pumpa To: Public CC: Followers

    Magnet is required to acknowledge the use of private keys.

  • Metal enclosures which attach to ZL271

    2018-10-01T07:39:33Z via Pumpa To: Public CC: Followers

    ZL271 is attached. I drilled a hole to the left one.

  • Enclosures which attach to ZL271

    2018-10-01T07:38:08Z via Pumpa To: Public CC: Followers

    Here are possible enclosures (bottom-right is ZL271).

    Red one and blue one are original "wristband" versions.

    Now, I consider using the metal version (left), drilling a hole for LED.

    One of Bat man or Spider man would infringe copyright.

    These are parts for FST-01SZ. Left is the metal enclosure, right is the connector to USB.

  • FST-01SZ prototype revision #1

    This is the prototype. Functionality-wise, it should be OK.

  • FST-01SZ, an expeliment with GD32F103

    2018-09-21T02:11:32Z via Pumpa To: Public CC: Followers

    I'm testing Gnuk running at 96MHZ with my proto-type board.
    I named it FST-01SZ, where SZ stands for ShenZhen.
  • EuroBSDcon and Gnuk Token

    2018-08-29T05:06:43Z via Pumpa To: Public CC: Followers

    It seems that Gnuk Token will be distributed (possibly free of charge) at EuroBSDcon.

    I was asked those who plans to do it.
  • USB ID and the repository

    2018-07-01T23:51:11Z via Pumpa To: Public CC: Followers

    For some unknown reason, the maintainer has not yet registered our official USB ID to the database (for years).

    https://usb-ids.gowdy.us/read/UD/234b

    Today, I digged up the files (of physical papers), and found this one which was sent by FAX.

    I wonder if it's enough evidence to be registered to the repo.
  • De-facto standard of Wrist USB

    2018-06-28T02:10:59Z via Pumpa To: Public CC: Followers

    In China, it seems that there is de-facto standard of PCB for the wrist USB.
    Manufacturer offers the band independently.

    I'm considering this type of USB device.
