1. Unzip the folder and you'll find 3 files. A makefile, example binary and Readme.txt file. 

2. Please make sure you place the binary in the same folder as you have your makefile and open the command prompt where the makefile is present.

3. Then run the following command with the following parameters being passed,

OUTNAME= <YOUR_BINARY_NAME_WITHOUT_EXTENSION>

EXTN        = <EXTENSION_OF_YOUR_BINARY_WITHOUT_THE_DOT> (Ex: xer5f, out, elf etc.,)

4. Inside the makefile_ccs_bootimage_gen file, please update the below fields so the script can pick correct tool chain paths.
MCU_PLUS_SDK_PATH = <PATH_TO_MCU_PLUS_SDK>

CG_TOOL_ROOT = <PATH_TO_YOUR_COMPILER>

5. Example command to be run from the command prompt looks like this, 

BUILD the appimage - gmake -s OUTNAME=TestSuit EXTN=out DEVICE=AM263x all

Clean the targets - gmake -s OUTNAME=TestSuit EXTN=out DEVICE=AM263x clean

Adding other core's rprc file - 

gmake -s OUTNAME=TestSuit EXTN=out DEVICE=AM263x 
R50_1_RPRC=<path_to_r50_1_core_rprc> R51_0_RPRC=<path_to_r50_1_core_rprc> R51_1_RPRC=<path_to_r51_1_core_rprc>
