AM3358: U-Boot Debugging Problem on the AM3358 Based Board

Part Number: AM3358

Tool/software:

I follow that steps (software-dl.ti.com/.../Apps-Load-in-CCS.html)

After load the program(u-boot) Console gives "CortxA8: AutoRun: Target not run as the symbol "main" is not defined"

And also resume and stop the operation debugger stuck on the get_bad_stack (vectors.S data_abort:) and U Boot console didn't send anything on the serial terminal.(even CCCC)

How can i debug the program?

Best regards.

All of the my console output is the

CortxA8: Output: **** AM335x BeagleBlack Initialization is in progress ..........
CortxA8: Output: **** AM335x ALL PLL Config for OPP == OPP100 is in progress .........
