xWRL6432 EVM

Note

For more details/documentation, search for your EVM on https://www.ti.com

Cable Connections

• The figure below shows some important cable connections, ports and switches.
  • Take note of the location of the "SOP" switch, this is used to switch between different boot modes.

Setup UART Terminal

• 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.

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 (as identified above), keep other options to default, i.e 115200 baud rate - 8 data bits - No parity - 1 stop bit,

Note

In this screenshot this happens to be COM13 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.

SOP Mode Configuration

SOP Mode	Mode Name	Combination (S1.2, S1.1)
SOP_MODE1	Device management mode	OFF , OFF
SOP_MODE2	Application Mode/ Functional Mode	OFF , ON
SOP_MODE3	Test Mode	ON , OFF
SOP_MODE4	Debug Mode	ON , ON

Mux Table

Certain peripherals are multiplexed, based on usage of peripherals configure Mux as per below table.

	Switch Position OFF	Switch Position ON
S1.3	LVDS	LIN_RX, XDS_UARTA/CAN, NERROR_LED, WATCH_DOG_TP, RTC_CLK_IN_TP, HOST_CLK_TP
S1.4	XDS_RS232	DCA_LP_RS232
S1.5	CAN	XDS_UARTA
S1.6	I2C, REG_MODE, LED_SW_GPIO	SPI
S4.1	XDS_JTAG	DCA_JTAG

Control Table

	Switch Position OFF	Switch Position ON
S4.2	CAN PHY: Stand-by Mode Disable	CAN PHY: Stand-by Mode Enable
S4.3	LIN PHY: Enable	LIN PHY: Disable
