# Setup UART Terminal

## AM261X-LP

- Many examples use a standard UART terminal to log the output from the examples. You can use any UART terminal program for the same. Below steps show how to setup the UART terminal from CCS.
- First identify the UART port as enumerated on the host machine.
  - Make sure that the EVM and UART cable connected as shown in Cable Connections
  - In windows, you can use the "Device Manager" to see the detected UART ports
    - Search "Device Manager" in Windows Search Box in the Windows taskbar.
  - If dont see any USB serial ports listed in "Device Manager" under "Ports (COM & LPT)", then make sure you have installed the UART to USB driver from FTDI, https://www.ftdichip.com/FTDrivers.htm.

Identify UART Port in Windows Device Manager

- In CCS, goto "View > Terminal"

UART Terminal Menu

- Open a new UART terminal

Open New UART Terminal

- Select the UART port, keep other options to default, i.e 115200 baud rate - 8 data bits - No parity - 1 stop bit,
  - We use this serial port, as seen in the device manager, for below in the SDK
    - Flashing application via UART
    - Booting application via UART
    - Console output for examples

Connect to UART port

- In this screenshot this happens to be COM5/COM11 however on your machine this could be different. One tip to make sure there is no mistake in identifying the UART port is to disconnect all other UART to USB devices other than this EVM before checking in device manager.

# Additional Details

## BOOT MODE

### OSPI BOOT MODE

This mode is used to boot flashed applications via EVM flash like OSPI flash.

#### AM261X-LP

BOOTMODE [ 1 : 4 ] (SW1) = 1100

OSPI BOOT MODE

#### AM261X-SOM

BOOTMODE [ 1 : 4 ] (SW1) = 1100

OSPI BOOT MODE

### UART BOOT MODE

This mode is used to flash files to the EVM flash via UART. It can also be used to boot applications via UART.

#### AM261X-LP

BOOTMODE [ 1 : 4 ] (SW1) = 0111

UART BOOT MODE

#### AM261X-SOM

BOOTMODE [ 1 : 4 ] (SW1) = 1000

UART BOOT MODE

### DEVBOOT MODE

This mode is used in CCS.

#### AM261X-LP

BOOTMODE [ 1 : 4 ] (SW1) = 0010

NO BOOT MODE

#### AM261X-SOM

BOOTMODE [ 1 : 4 ] (SW1) = 1101

NO BOOT MODE

### DFU BOOT MODE

This mode is used with DFU bootloader and DFU Uniflash.

#### AM261X-LP

BOOTMODE [ 1 : 4 ] (SW1) = 1000

DFU BOOT MODE

#### AM261X-SOM

BOOTMODE [ 1 : 4 ] (SW1) = 0111

DFU BOOT MODE
