AM2732: May I get the general SBL project or image to apply to my project?

I would like to flash my program to the flash memory and to run my application program.

Actually I don't need SBL. I just want to execute my application program.

If the SBL is need to run program, Should I do the coding for SBL ?

Then should I make me understood about the SBL and the detailed ?

Please let me know the method to run my program from flash memory.

When I try to make the example project of the SDK, it result an error. 

- project name: sbl_qspi_am273x-evm_r5fss0-0_nortos_ti-arm-clang

- error name: makefile_ccs_bootimage_gen:65: recipe for target 'all' failed

Can this example apply to my project?
