SIM (SmartCard) driver for i.mx25 (LINUX)

[V_Palacio]

Hello All,

I have ported a SIM driver from i.mx51 to i.mx25. Now, when driver is fully ported (i.e., compiles and initializes SIM related hw), I 'm trying to use it, but there is no documentation about driver.

 https://lists.ubuntu.com/archives/kernel-team/2009-July/006395.html

Anybody have experience using SIM/SmartCard driver for i.mx51?

Regards,

    For iMX25 board, to enable the SIM, you need add "sim" in uboot command lines, without this "sim", the code to config pins for SIM will be skipped in kernel file "mx25_3stack-gpio.c".

    The SIM card test code can be found at "imx-test-09.12.00\test\mxc_sim_test\", it works for iMX25 3stack board with L2.6.31_09.12.00 BSP.

Dear Qiang Li,

I have 2 questions for SIM control,

1 for adding "sim" in uboot command line and 1 for performing the SIM Test by using "mxc_sim_test.out".

1) "sim" uboot command line

   - How do I add "sim" in uboot command line?

     Could you show me the example to add "sim" in uboot command line?

   - I think the below will be an example,

     Change the bootargs_base of u-boot environment,

      from "setenv bootargs console=ttymxc0,115200"

      to "setenv bootargs console=ttymxc0,115200 sim"

2) perform the SIM Test

   - How do I perform the SIM Test by using mxc_sim_test.out "imx-test-09.12.00\test\mxc_sim_test\"?

   - In the code, I showed the SIM command usage,  "~ $ gsmdemo <pin>".

     So I think I can perform the SIM Test with "./mxc_sim_test.out <pin>"

     But I don't know what is the <pin>.

   - Now I'm using the SIM1_TX pin of SIM1(CSI_D5 pin of CPU) as Inout Data pin.

Best Regards,

Eric.

[qiang_li-mpu_se]

For 1), you are right.

For 2), for pin, after checked the code, I think it hasn't been used, you can fill any value for pin. The test will dump some information from the SIM card and print out on console.

Dear Qiang Li,

Thanks for your response.

I have 2 questions for the SIM Interface.

1) SIM Application build method as standalone

    - I saw the Makefile in the imx-test-09.12.01/test/mxc_sim_test.

      I could build the mxc_sim_test.out file by using this Makefile.

      But I want to build the mxc_sim_test.c file as standalone.

      How do I build the mxc_sim_test.c file?

      In the Makefile, the file is built by using the below commmand.

      $(CC) -lpthread -o $(TARGET) $(OBJS) -lsim

    - In other words, I want to build the only mxc_sim_test.c file.

      For example, I will build the file like as the below commands.

      arm-none-linux-gnueabi-gcc mxc_sim_test.c -o mxc_sim_test

      with SIM library like as -lpthread and -lsim

      I want to know how to apply the -lpthread and -lsim library in the single build command line.

2) User Space Library

    - I confirmed the below SIM interface information

      in the "Chapter 27.2 Software Operation of SIM Driver" of i.MX25 PDK Linux Reference Manual.

      The SIM interface driver package for the i.MX familiy consist of two basic parts

      : the SIM kernel interface driver and the a user space library to simplify development.

    - Could you give me
      the User Space Library API Document and the source code for the User Space Library?

Best Regards,

Eric.

    The libsim.so code can be found at "imx-lib-09.12.00\sim".  There is no API document, but you can find the description for those APIs in file "iso7816-3.c".

    Attached is two example "Makefile" to make the libsim.so and mxc_sim_test.out alone. You can unzip and put them into your home folder of Linux system. You need to check the followed setting in the Makefile to meet your PC setting before make them, and libsim should be made first.

TOOL_DIR =/opt/freescale/usr/local/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin

CC=$(TOOL_DIR)/arm-none-linux-gnueabi-gcc

PLATFORM_INC_DIR = /home/user/ltib/rpm/BUILD/linux-2.6.31/include

LIBSIM_DIR = "/home/user/libsim"

Hi,

I'm involved with the same quest. When I run the "./mxc_sim_test.out <pin>", I got the following answer: "ReaderStart -22 2".

I saw into "mxc_sim_test.c" code that's an error. I think the error cause is the missing device "/dev/mxc_sim". In my rootfs there is no "/dev/mxc_sim" device.  I also think ltib creates the device.

Anyone of you could help me?

For noticing, the error occours in both boot modes, nand and nfs.

My u-boot variables are:

bootargs_base=setenv bootargs console=ttymxc0,115200 sim

bootcmd_net=run bootargs_base bootargs_nfs; tftpboot ${loadaddr} ${kernel}; bootm

bootcmd_nand=run bootargs_base bootargs_nand; nand read ${loadaddr} 0x300000 0x200000;bootm

I really appreciate your help.

[qiang_li-mpu_se]

For default setting, the SIM driver was built as module, did you insmod the "imx_sim.ko" before run the sim test application?

If the sim driver was loaded successfully, you should see the device "/dev/mxc_sim" in your run time rootfs.

[leonardoalmeida]

Hi, Qiang Li.

I've also located the module into ltib menu, and I changed it for "* ", instead of "M". After that, the device appears into "/dev". And I can send commands for the card now!

Now I have read your answer, I came back the configuration for "M" and the module was up, as the device. Is there any configuration for loading the modules automatcally?

Thanks for the help.

edit: Now I have other problem.When I run the test, I got errors for PDU commands. I tried to create my own test, sending command manually, and I still got error. The response is always 0x6060. I think it might be configuration parameters problem or driver problems. Anyway, I think the test should work. I've tried with two smartcards.

Dear Qiang Li,

Thanks for your rapid response.

I confirmed the SIM operation with your files, libsim and mxc_sim_test.

Best Regards,

Eric.

[erickang]

Thanks for your response.

I'll let you know the result after the SIM Operation.

[fabio_estevam]

The upcoming Freescale Linux BSP (SDK1.6) does provide SIM driver for MX51 and MX25.

Fabio Estevam

[erickang]

Dear Fabio Estevam,

I have a question for Freescale Linux BSP version.

You mentioned the SDK1.6 as the Freescale Linux BSP version.

How can I confirm the SDK version in the downloaded BSP?

I'm using the L2.6.31_09.12.00_SDK_source.tar.gz.

Best Regards,

Eric.
