Attention: This document contains the details for AM243X-EVM and AM243X-LP board setup under each section. User should select the right board setup in the sections.

Cable Connections

AM243X-LP

The figure below shows some important cable connections, ports and switches.
- Take note of the location of the "BOOTMODE" switch, this is used to switch between different boot modes like OSPI, UART, NOBOOT mode

AM243X-LP

Power Supply for LP board
- AM243X-LP has USB Type-C connector(J10) used for power input.
  - Need to input 5V with 3A power supply through the USB Type-C cable.
  - If there is error in power input then LD9 Red LED will glow continuously as shown in below image.

Power Error LED

If proper power input is supplied to LP board then LD9 RED Led will blink once and green leds will glow as shown in the below image

Power Indication LEDs

AM243X-EVM

The figure below shows some important cable connections, ports and switches.
- Take note of the location of the "BOOTMODE" switch, this is used to switch between different boot modes like OSPI, UART, SD, NOBOOT mode

AM243X-EVM

Device Type Identification

The MCU+SDK supports two device types: HS-FS (High Security - Field Securable) and GP (General Purpose). The HS-FS is the main device type and the support for GP device is deprecated. Please use SoC ID parser Python Script to identify the device type.

Note: It is recommended to know the device type before loading or flashing the binary into the target.

Setup UART Terminal

AM243X-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 AM243X-LP and UART cable connected as shown in Cable Connections
- AM243X-LP supports single UART Port from XDS110 JTAG which is used for console.
- 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, keep other options to default, i.e 115200 baud rate - 8 data bits - No parity - 1 stop bit,
- We use UART 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 which run from R5F

Connect to UART port

In this screenshot this happens to be COM148, 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 AM243X-LP before checking in device manager.

Flash SOC Initialization Binary

AM243X-LP

Attention: This is a recommended one time step that needs to be done before you can load and run programs via CCS; If this step fails, maybe due to bad flash in EVM, then try one of the other SOC initialization steps mentioned at SOC Initialization; This step needs to be done once unless the OSPI flash has been erased or some other application has been flashed

A quick recap of steps done so far that are needed for the flashing to work
- Make sure the UART port used for terminal is identified as mentioned in Setup UART Terminal
- Make sure python3 is installed as mentioned in Python3
- Make sure you have the EVM power cable and UART cable connected as shown in Cable Connections
POWER-OFF the AM243X-LP
Set boot mode to UART BOOTMODE as shown in below image

UART BOOT MODE

POWER-ON the AM243X-LP
You should see character "C" getting printed on the UART terminal every 2-3 seconds as shown below

UART output in UART BOOT MODE

Close the UART terminal as shown below. This is important, else the UART script in next step wont be able to connect to the UART port.

Close UART terminal

Open a command prompt and run the below command to flash the SOC initialization binary to the LP.
```
  cd ${SDK_INSTALL_PATH}/tools/boot
  python uart_uniflash.py -p COM<x> --cfg=sbl_prebuilt/am243x-lp/default_sbl_null.cfg
```
- Here COM<x> is the port name of the identified UART port in Windows.
- On Linux,
  - The name for UART port is typically something like /dev/ttyUSB0
  - On some Linux systems, one needs to use python3 to invoke python3.x, just python command may invoke python 2.x which will not work with the flashing script.

When the flashing is in progress you will see something like below

  C:\ti\mcu_plus_sdk_am243x_09_00_00_00\tools\boot>python uart_uniflash.py -p COM13 --cfg=sbl_prebuilt\am243x-lp\default_sbl_null.cfg

Click on browse and select the CPU reset gel, which should be under <CCS_DIR>/ccs/ccs_base/emulation/gel/AM64x/CPU_reset.gel
Save the target configuration file.

DDR Initialization

Attention: As AM243X-LP has no DDR memory, These DDR Initialization steps applicable only for AM243X-EVM.

AM243X-EVM

All SOC initialization methods using SBL initialize DDR by default. So DDR need not be enabled explicitly.
However, if you use the SOC Initialization Using CCS Scripting method, you need to initialize DDR using GEL files as explained below.
To initialize DDR, do the additional step below from CCS GEL menu.
Launch CCS debug session as mentioned here, Launch CCS
Connect to MAIN_Cortex_R5_0_0

Connect to R5F0-0

Run the DDR initialization from GEL menu as shown below,

DDR initialization via GEL menu

After the DDR initialization is done you will see prints like below in the CCS "CIO" console,

  MAIN_Cortex_R5_0_0: GEL Output: --->>> DDR4 Initialization is in progress ... <<<---
  MAIN_Cortex_R5_0_0: GEL Output: --->>> ECC Disabled <<<---
  MAIN_Cortex_R5_0_0: GEL Output: --->>> DDR controller programming in progress.. <<<---
  MAIN_Cortex_R5_0_0: GEL Output: --->>> DDR controller programming completed... <<<---
  MAIN_Cortex_R5_0_0: GEL Output: --->>> DDR PI programming in progress.. <<<---
  MAIN_Cortex_R5_0_0: GEL Output: --->>> DDR PI programming completed... <<<---
  ...
  MAIN_Cortex_R5_0_0: GEL Output: --->>> DDR Initialization completed... <<<---
  MAIN_Cortex_R5_0_0: GEL Output: --->>> DDR4 Initialization is DONE! <<<---

Now you can load programs to DDR and they can access DDR. Note, however for R5F and M4F to access DDR, there needs to be a MPU region setup to cover the DDR memory. By default, most SDK examples dont setup this MPU region. Also all code that executes before this MPU region is setup MUST NOT execute from DDR.

Additional Details

Note: This section has more details on AM243X-EVM and AM243X-LP. This is mainly for reference and can be skiped unless referred to by other pages in this user guide.

SOC Initialization

Before any program can be loaded and run on the EVM, the SOC needs to be initialized. Below sections describes the various options available for SOC initialization.

It is recommended to use the method mentioned in Flash SOC Initialization Binary. However in some cases, additional methods described below can be used esp when running on your own custom EVM and flash driver is not yet available for that EVM.

SOC Initialization Using SD BOOT

Attention: These steps applicable only for AM243X-EVM, AM243X-LP has no SD support.

Note: This step needs to be done once, unless the SD card is reformatted and/or the boot file is changed

Format a micro-SD card to contain a FAT partition as the primary partition
In windows,
- Insert a micro-SD in a USB card reader, connect to the PC.
- In "Windows Explorer", select the SD drive, right-click, select "Format"
  
  Format SD Card
- Format as FAT filesystem
  
  Format as FAT partition
- After formatting is done, you need to mark the partition as "ACTIVE".
  - There are various ways to do this in Windows, see online forums for various options
  - Here we use the GUI tool "Active Partition Manager" http://www.pcdisk.com/index.html
    - Download and install the tool
    - Launch the tool and select "Open Disk Image"
    - You will see all the disks present on the system, including the SD card FAT partition
    - Right click on the SD card FAT partition
    - Select "Change Attributes"
    - Enable the option "Mark Partition As Active", click "OK"
    - Close the application
In Linux,
- Refer to online forums to create FAT partition on a SD card and set it as "ACTIVE"
- gparted is one GUI based tool that can be used to create partitions, format them and set them as "ACTIVE"
```
sudo apt install gparted
```

Copy the below file to the newly formatted FAT partition on the SD card and rename it as tiboot3.bin

  copy file to SD card => ${SDK_INSTALL_PATH}/tools/boot/sbl_prebuilt/am243x-evm/sbl_null.release.hs_fs.tiimage
  rename in SD card as => tiboot3.bin

Eject the SD card
POWER-OFF the EVM
Set EVM to SD BOOT MODE by setting the switch setting as shown below

SD BOOT MODE

Insert the formated SD card in the SD card slot in the EVM
Open a UART terminal as mentioned in Setup UART Terminal
POWER-ON the EVM

You should see output like below on the UART terminal

You dont need to do these steps again unless you have changed or re-formatted or deleted/changed the tiboot3.bin file.

SOC Initialization Using CCS Scripting

Set Environment Variable

Note: This step needs to be done once and is needed for the SOC initialization script load_dmsc_hsfs.js to find certain initialization files within the SDK folder. This variable is not used otherwise in the build process. If you dont like adding variables in the environment, then you need to edit the file ${SDK_INSTALL_PATH}/tools/ccs_load/am243x/load_dmsc_hsfs.js and specify the SDK path in the file itself.

Add path to the SDK folder as a environment variable in the host machine.
In windows, goto "Windows Task Bar Search" and search for "environment variables for your account"

Environment Variables For Your Account
Add a new variable named MCU_PLUS_SDK_AM243X_PATH and point it to the path where the SDK is installed

Add New Environment Variable For Your Account

In Linux, usually you need to add a line as below in the ${HOME}/.bashrc,

  export MCU_PLUS_SDK_AM243X_PATH=${HOME}/ti/mcu_plus_sdk_am243x_{sdk version}/

If CCS is open, close and reopen CCS for the CCS to be able to see the updated environment variable

Run the SOC Initialization Script

AM243X-LP

Attention: This step needs to be done every time the AM243X-LP is power-cycled.

POWER-OFF the AM243X-LP
