Attention: Flashing a application will overwrite the SOC init application that was flashed earlier. So if you want to load and run from CCS again, you will need to do the SOC init steps again. See SOC Initialization for more details.; As the wake-up R5 is the device manager, it needs to be started by the SBL. So it can not be loaded through CCS. It should be flashed and booted through SBL.

Note: See also Flashing Tools for more details on the flashing tools.

Introduction

In this step we will flash the application that we have build and run using CCS to the EVM flash. We can then boot this application without being connected to CCS via JTAG.

Getting ready to flash the application

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
Build the hello world application as mentioned in Build a Hello World example
As part of the build process in the final step a file with extension .appimage.hs_fs is generated. This is the file we need to flash.
- When building with makefiles and single-core projects, this file can be found here (shown for hello world example),
  - For MCU R5F
```
 ${SDK_INSTALL_PATH}/examples/hello_world/am62ax-sk/mcu-r5fss0-0_freertos/ti-arm-clang/hello_world.release.appimage.hs_fs
```
  - For DM R5F (WKUP R5F)
```
 ${SDK_INSTALL_PATH}/examples/hello_world/am62ax-sk/r5fss0-0_freertos/ti-arm-clang/hello_world.release.appimage.hs_fs
```
  - For c75
```
 ${SDK_INSTALL_PATH}/examples/hello_world/am62ax-sk/c75ss0-0_freertos/ti-c7000/hello_world.release.appimage.hs_fs
```
- When building with CCS projects, this file can be found here (shown for hello world example),
  - For MCU R5F
```
 ${CCS_WORKSPACE_PATH}/hello_world_am62ax-sk_mcu-r5fss0-0_freertos_ti-arm-clang/Release/hello_world_am62ax-sk_mcu-r5fss0-0_freertos_ti-arm-clang.appimage.hs_fs
```
  - For DM R5F (WKUP R5F)
```
${CCS_WORKSPACE_PATH}/hello_world_am62ax-sk_r5fss0-0_freertos_ti-arm-clang/Release/hello_world_am62ax-sk_r5fss0-0_freertos_ti-arm-clang.appimage.hs_fs
```
  - For C75 ${CCS_WORKSPACE_PATH}/hello_world_am62ax-sk_c75ss0-0_freertos_ti-c7000/Release/hello_world_am62ax-sk_c75ss0-0_freertos_ti-c7000.appimage.hs_fs
- NOTE: The folder name and file name in path can have "release", "Release" or "debug", "Debug" based on the profile that the application is built with.
Next, we need to list the files to flash in a flash configuration file. A default configuration file can be found at below path. You can edit this file directly or take a copy and edit this file.
```
  ${SDK_INSTALL_PATH}/tools/boot/sbl_prebuilt/am62ax-sk/default_sbl_ospi_nand_linux_hs_fs.cfg
```
Note
For HS-SE device, use default_sbl_ospi_linux_hs.cfg as the cfg file.

For HS-FS device, use default_sbl_ospi_linux_hs_fs.cfg as the cfg file.

Edit below line in the config file to point to your application .appimage file. Give the absolute path to the .appimage file or path relative to ${SDK_INSTALL_PATH}/tools/boot. Make sure to use forward slash / in the filename path.

For MCU R5F

--file=../../examples/drivers/ipc/ipc_rpmsg_echo_linux/am62ax-sk/mcu-r5fss0-0_freertos/ti-arm-clang/ipc_rpmsg_echo_linux.release.appimage.hs_fs --operation=flash --flash-offset=0x800000

For DM R5F

--file=../../examples/drivers/ipc/ipc_rpmsg_echo_linux/am62ax-sk/r5fss0-0_freertos/ti-arm-clang/ipc_rpmsg_echo_linux.release.appimage.hs_fs --operation=flash --flash-offset=0xC0000

For C75

--file=../../examples/drivers/ipc/ipc_rpmsg_echo_linux/am62ax-sk/c75ss0-0_freertos/ti-c7000/ipc_rpmsg_echo_linux.release.appimage.hs_fs --operation=flash --flash-offset=0xA00000

This file will additionally also list the flashing application that is run on the EVM and a OSPI flash bootloader that also needs to be flashed. You can keep this unchanged if you have not modified these applications.
Save and close the config file.

Building Linux app image and HSM app image

The linux and HSM app images are to be generated to flash along with your application for MCU R5.

LinuxAppImage

Note: For HS-SE device, use DEVICE_TYPE=HS option in the makefile.

Ensure the AM62AX Processor SDK Linux path is correct in the ${SDK_INSTALL_PATH}/tools/boot/linuxAppimageGen/board/{board_name}/config.mak file.
Go to ${SDK_INSTALL_PATH}/tools/boot/linuxAppimageGen on terminal
Run the following command to build the linux app image.
- For SK-AM62A-LP
  make BOARD=am62ax-sk all

HSMAppImage

Note: For HS-SE device, use DEVICE_TYPE=HS option in the makefile.

Go to ${SDK_INSTALL_PATH}/tools/boot/HSMAppimageGen on terminal
Run the following command to build the HSM app image.
- For SK-AM62A-LP
  make BOARD=am62ax-sk all

Flashing the application

Build all the binaries
- For Linux
  make DEVICE=am62ax -sj
- For Windows
  gmake DEVICE=am62ax -sj
POWER-OFF the EVM
Set boot mode to UART BOOTMODE as shown in below image

UART BOOT MODE

POWER-ON the EVM
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

Note: For HS-SE device, use default_sbl_ospi_nand_linux_hs.cfg as the cfg file.; For HS-FS device, use default_sbl_ospi_nand_linux_hs_fs.cfg as the cfg file.

Open a command prompt and run the below command to flash the SOC initialization binary to the EVM.
```
  cd ${SDK_INSTALL_PATH}/tools/boot
  python uart_uniflash.py -p COM13 --cfg=sbl_prebuilt/am62ax-sk/default_sbl_ospi_nand_linux_hs_fs.cfg
```
- Here COM13 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

Flash in progress

After all the flashing is done, you will see something like below
