Booting DM36x Out of the Box

From Texas Instruments Wiki
Jump to: navigation, search

NOTE: The EVM (beta version and later) is configured at manufacturing to allow the board to boot up Linux out of the box without having to build or install any additional software. For earlier versions of EVM (alpha or pre-alpha), user still needs to flash U-Boot and UBL to flash.

Use the following steps to boot the board:

  1. Connect the serial cable included with the kit to the serial port of the EVM board and connect the other end to the serial port of a workstation.
  2. Make sure the the boot switch pins on switch SW4 are in the correct position:
  3. For NAND boot mode:

    S4:1 (BITSEL2) S4:2 (BITSEL1) S4:3 (BITSEL0) S4:4 (AECFG2) S4:5 (AECFG1) S4:6 (AECFG0)

    For MMC/SD boot mode:

    S4:1 (BITSEL2) S4:2 (BITSEL1) S4:3 (BITSEL0) S4:4 (AECFG2) S4:5 (AECFG1) S4:6 (AECFG0)
  4. Run a terminal session on your workstation and configure it to connect to the serial port with the following settings
    • Bits per second: 115,200
    • Data bits: 8
    • Parity: None
    • Stop bits: 1
    • Flow control: None
    • Transmit delay: 0 msec/char, 100 msec/line
  5. Upon powering up the board, you should see U-Boot start up and then messages indicating that the Linux kernel is starting up. When the boot sequence has completed, you should see a login prompt.
  6. Log in as root (no password).
    • At the Linux prompt, you can use existing Linux commands to test various features and use examples from the "examples" folder under the "images" directory.
    • While U-Boot is booting, you can press any key to interrupt the automatic boot of the Linux kernel. This will leave you in U-Boot, where you can type commands in the U-Boot command shell.
