The following Errata applies for the following serial numbers:

Effective: 4/16/2012

These issues are currently being investigated by Critical Link Engineering. For updates please visit http://support.criticallink.com/redmine/projects/am335x-devkit.

  • There is an error in the environment setup script on early (before 4/20/2012) versions of the MitySOM-335X development kit SDK virtual machine configuration. The TI SDK was not installed correctly and the SDK_PATH is set incorrectly. This will cause issues trying to build with the toolchain. To correct this issue, comment out line 10 in /usr/local/ti-sdk-am335x-evm-05.03.02.00/linux-devkit/environment-setup like this.
    export SDK_PATH=/export/space/ti-sdk-am335x-evm-05.03.02.00/linux-devkit
    

    Note: you will need to have root privilege to do this. The sudo command should be used to edit the file. If you are using vi, the command is
    sudo vi /usr/local/ti-sdk-am335x-evm-05.03.02.00/linux-devkit/environment-setup.
  • Some boards have intermittent issues communicating with U101 [ADS1000A Analog to Digital Converter]. The error is
    tcI2CDevice::Open:ioctl:: Device or resource busy
    additionally, i2cdump reports
    root@mityarm-335x:~# i2cdump -y 1 0x48 w
    Error: Could not set address to 0x48: Device or resource busy
    

    Other boards seem to be ok.
  • The analog input circuit s (via J900) should not be used at this time.
  • The video decode demos do not run because of a hostname change. The tar file at http://support.criticallink.com/redmine/attachments/download/1509/am335x_video_demo_patch.tgz
    contains corrected scripts. cd to / and tar xvzf the file to update the scripts in /usr/bin

  • The Graphics development kit (v 4.05.00.03 is included with the VM image, but not installed). To install it you will need to do the following:
    - sudo chmod +x /usr/local/ti-sdk-am335x-evm-05.03.02.00/Graphics_SDK_setuplinux_4_05_00_03.bin
    - /usr/local/ti-sdk-am335x-evm-05.03.02.00/Graphics_SDK_setuplinux_4_05_00_03.bin
  • The RS-232 expansion card revision 1 (80-000450RI-1) DB-9 pin 5 ground is not connected. This may affect users where the far end of the serial link is on a different ground reference. Most users should not notice a problem. As a workaround, a solder bridge can be made from pin 5 to the surrounding ground pour on the circuit board.
