Board Detail : imx6 Sabre SD board (Imx6q processor)


I am trying to load standalone program (hello_world.bin) which is available in u-boot source code folder,but after running standalone code board is getting RESET, I have done few modification in u-boot source code

In /arch/arm/ file CONFIG_STANDALONE_LOAD_ADDR has been modified to 0x12000000 

also In include/configs/mx6_common.h CONFIG_LOADADDR has been modified to 0x12000000.


I am using SD Card to load bin file to RAM . and using GO command. Can anyone suggest where I am doing mistake, is there any steps I missing.
