5. EVM Setup for AM65xx

This section is intended to give a quick reference of IDK/EVM related to SDK usage. Full IDK/EVM documentation can be referenced at AM65x evaluation module https://www.ti.com/tool/TMDX654IDKEVM and https://www.ti.com/tool/TMDX654GPEVM.

Important

  • The power supply current requires more than 1A @12V input

  • DisplayPort-to-DVI or DisplayPort-to-HDMI adapters don’t work with DisplayPort

  • The SOM board has to be tightly inserted into the connector sockets.

5.1.2. UART terminal setup

  • Connect USB cable to FTDI USB port (J42) on common processor board (see IDK Application Board)

    • 4 UART ports would be visible at the PC side

    • First COM port – SoC MAIN UART0

    • Second COM port – MCU UART

    • Third COM port – Wakeup UART

    • Fourth COM port – SoC MAIN UART1

  • Setup UART for 115200 baud rate, 8 data bits, no party, 1 stop bit

5.1.3. Boot Modes

Bootmodes are selected using the SW2 and SW3 switches on the common processor board. See the image below

_images/K3-AM65X-IDK-bootswitch.png

Note that 0 indicates OFF and 1 indicates ON

No Boot Mode

Use following settings for MCU_BOOTMODE pins

SW4[1-2] = 00

5.1.3.1. No Boot Mode

When you want the binaries to be loaded from a debugger (CCS), the common processor boards has to be set in the NO boot mode.

Following are the switch settings to do the same.:

SW2[1-8] = 0010 0000
SW3[1-8] = 0000 0000

5.1.3.2. SD Boot Mode

Following are the switch settings to set the boot mode to SD for common processor board.:

SW2[1-8] = 0010 0000
SW3[1-8] = 0110 0000

5.1.3.3. OSPI Boot Mode

Following are the switch settings to set the boot mode to OSPI for common processor board.:

SW2[1-8] = 1000 0000
SW3[1-8] = 1000 0000

5.1.3.4. UART Boot Mode

Following are the switch settings to set the boot mode to SD for common processor board.:

SW2[1-8] = 0010 0000
SW3[1-8] = 0101 0000
