CCS/CC1310: CC1310 official OAD project rfWsnNodeIntFlashOadClient compile with memery problem

Part Number:CC1310

Tool/software: Code Composer Studio

In Ti official project rfWsnNodeIntFlashOadClient_CC1310_LAUNCHXL_tirtos_ccs, SDK simplelink_cc13x0_sdk_1_50_00_08， i use CCS7 to compile the  OAD image but it fail with memery problem .

compile error is :../CC1310_LAUNCHXL_TIRTOS_OAD.cmd", line 86: error #10099-D: program will not fit into available memory.  placement with alignment fails for section ".const" size 0x4c58 .  Available memory ranges:
   FLASH        size: 0xeff0       unused: 0x3a06       max hole: 0x39f6    
error #10010: errors encountered during linking; "rfWsnNodeIntFlashOadClient_CC1310_LAUNCHXL_tirtos_ccs.out" not built.

It seems that the oad image flash size is more than 60KB limit which inflash OAD image should under.

The problem occur after I follow the project guide /ti/simplelink_cc13x0_sdk_1_50_00_08/examples/rtos/CC1350_LAUNCHXL/easylink/rfWsnNodeIntFlashOadClient/README.html.

here is the guide:

Building the hex file in CCS

1. Import the CCS porject into CCS(for more information conslt the Examples Users Guide in the proprietary-rf documentation)
2. If this is for an OAD image (not an image to be flashed), then exclude the ccfg.c file from the project.
3. Add FEATURE_OAD_ONCHIP and HAL_IMAGE_A or HAL_IMAGE_B to the predefined Symbols in Project->Properties Arm Compiler / Predefined Symbols tab (for Image B the TIRTOS config file must also be changed, see below).
4. Add FEATURE_OAD_ONCHIP=1 and HAL_IMAGE_A=1 or HAL_IMAGE_B=1 to the Linker symbol definition in Project->Properties ARM Linker->Advanced Options / Command File Preprocessing tab (for Image B the TIRTOS config file must also be changed, see below).
5. Enable hex file conversion in Project->Properties Arm Hex Utility
6. Set memory width to 8 in General options
7. Set output format to intel hex.
8. Make a code change update the nodeFwVersion string in NodeTask.c
9. build

The above macro change will set the program flash size to 0xEFF0 which I find in the project file  CC1310_LAUNCHXL_TIRTOS_OAD.cmd:

here is the source code:

#if defined(FEATURE_OAD_ONCHIP)
    #if defined(HAL_IMAGE_B)
        #define FLASH_BASE              0x10000
        #define FLASH_SIZE              0xEFF0
    #else // HAL_IMAGE_A
        #define FLASH_BASE              0x1000
        #define FLASH_SIZE              0xEFF0
    #endif
#else
    #define FLASH_BASE              0x1010
    #define FLASH_SIZE              0x1EFF0
#endif

So i try to set the FLASH_SIZE back to 0x1EFF0,the compile pass. But the program size is larger than 60KB, i can't create a useable OAD image.

The office project doesn't work. Should  i do  some addition settings in CCS7? Is it any way to reduce the flash size?
