急急急，请教请教！pre-define NAME中加入芯片型号后，会出现/Application/board_key.c", line 106: error #20: identifier "Board_BTN2" is undefined

芯片：CC2640R2F 7*7

SDK:simplelink_cc2640r2_sdk_4_30_00_08

CCS:Code Composer Studio 9.1.0

例程：C:\ti\simplelink_cc2640r2_sdk_4_30_00_08\examples\rtos\CC2640R2_LAUNCHXL\ble5stack\simple_peripheral

修改部分：只是修改了ble5_simple_peripheral_cc2640r2lp_app—propertise-Bulid/predefined symbols/Pre-define NAME如图所示

想要实现功能：在自制的板子上跑例程
