Loading an Application

Once the application image (.appimage/.mcelf) is created one needs to copy or flash these to a supported boot media so that the application can start executing once the SOC is powered ON

When flashing the application we also need to flash a bootloader or SBL image.

Loading via CCS

There are 3 methods to load a binary via CCS:

• Loading an existing .out
• Build and load .out directly in CCS
• Load .appimage via SBL JTAG UNIFLASH

Loading an executable in CCS

• A .out binary could be generated by either makefile build or via CCS build.
• To load a makefile generated binary, launch target configuration in CCS --> click load program --> click "Browse"
• Go to the binary path, select and click enter.
• To load CCS built binary, click on "Browse projects" instead and select the binary from the list of projects.
• For detailed explanation refer Load and run example binaries in CCS

Build and load using 1 click

• Projects imported in CCS can be loaded and run on the EVM with single click.
• Refer 1 Click Debug with CCS Projects for steps.

Loading appimage via SBL JTAG UNIFLASH

• This is a flash-writer example which uses JTAG to write files or erase flash.
• It can perform the following operations:
  • Flash the received file at the given offset
  • Verify if the data in the received file is present at the given offset
  • Erase the entire flash.
• Refer SBL JTAG Uniflash for steps.

Loading via TI Uniflash tool

• TI UniFlash Tool is used for programming "On-chip" and "External flash" memory on TI microcontrollers.
• It offers both GUI and command line interfaces.
• Refer TI Uniflash Tool for detailed information.

Script based loaders/flashwriters

Tool	Description
uart_bootloader.py	Sends the SBL and appimage binaries over UART using XMODEM protocol
uart_uniflash.py	Flashes SBL and applications to EVM flash using UART
can_bootloader.py	Sends the application binaries over CAN given the SBL is already flashed
can_uniflash.py	Flashes the application binaries after sending it over CAN given the SBL is already flashed

UART_BOOTLOADER

Refer UART Bootloader Python Script for details.

UART_UNIFLASH Flashwriter

Refer UART Uniflash for details.

CAN_BOOTLOADER

Refer CAN Bootloader Python Script for details.

CAN_UNIFLASH Flashwriter

Refer SBL CAN UNIFLASH for details.
