Can't build image

Feb 25 at 10:36 AM
I try build image from BSP, and I have 21 errors:

BUILD: [02:0000000919:ERRORE] C:\WINCE700\platform\AM33X_BBB_BSP\SRC\CSP\AM33X\OAL\CPUIDLE\cpu.s(930) : error A0034: undefined symbol: CONTROL_DDR_CMD_IOCTRL_0_OFFSET {log="C:\WINCE700\build.log(45162)"}

I try find information in Internet, and people write, that file "" including this constants... But my file doesn't contains it.

Can you help me?
