Getting started with AM335x and EtherCat

Other Parts Discussed in Thread: SYSBIOS, AM3359

Originally posted to the wrong forum.  Sorry for any confusion.  CC

Looking to develop an EtherCat slave based on the AM335x and I was planning on starting with the TMDXICE3359 <http://www.ti.com/tool/tmdxice3359> as a development board.  Before ordering I'd like to make sure that I am ordering everything I need.

I think I need:

  1. The TMDXIC3359 board <http://www.ti.com/tool/tmdxice3359>
  2. SYS/BIOS Industrial Software Development Kit software <http://www.ti.com/tool/sysbiossdk-ind-sitara>
  3. Code Composer Studio <http://www.ti.com/tool/ccstudio>
  4. an EtherCat master (like the Beckhoff TwinCat)

So a few questions:

  1. Is there anything else that I'll need to get started?  JTAG cables, power supply, other cables, software?
  2. Do I need to purchase a cope of Code Composer or can I use the free download version?
  3. Does the free version of Code Composer and the EtherCat SYS/BIOS work together on a WinXP 64bit machine? On Linux?

Thanks for any help

    1. Power supply for ICE board is included in the box you receive. It is 24V power supply with worldwide input voltage .

    2. Since the ICE board has a XDS100 on the board, it is okay to use CCS free version. Let us know if it does not work. 

    3. Win XP/7 are fine. We have tested Win XP 32-bit and Windows 7 32/64 bits. Linux should also work but it is not tested. If there is a problem using Linux, we will support it as Code Composer supports Linux.

    I'm setting up the toolchain to compile and download the "I2C_LED" demo application.

    I've downloaded and installed these packages:

    00 --> CCS5.1.1.00031_win32
        (http://processors.wiki.ti.com/index.php/Download_CCS)
    01 --> XDC_TOOLS
        (http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/rtsc/3_23_03_53)
    02 --> SYS_BIOS
        (http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/bios/sysbios/index.html)
    03 --> AM3359_SDK
        (http://software-dl.ti.com/dsps/dsps_public_sw/am_bu/AM335x_SYSBIOS_Industrial_SDK/01_00_00_03/index_FDS.html)

    Then I've imported the "i2c_led" project in eclipse as described in wiki page, but linker reports this error:

    Any suggestion?

    Solved: you have to make sure that the "Automatically import referenced projects" option in the Import CCS Eclipse Projects dialog is not checked.
