我按着CC2640 BLE OAD User's Guide的文档来做片内OAD升级，编译顺序为bim、cc2650em_stack、cc2650em_app，之后打开merge.bat报错内容为
Create combined HEX files
Merging: ..\..\..\util\bim\cc2640\iar\FlashOnly\Exe\bim.hex
Data overlapped at address 0x1FB00
Created app\oad_target_cc2650em_unified.hex
请按任意键继续. . .
为何会出现 “”Data overlapped at address 0x1FB00“”这个需要我更改哪个地方的设置？谢谢
