    This is my bat file code

    @echo off

    @set DEST_PATH=app\FlashROM\Exe
    @set MERGED_BIN=app\FlashROM\Exe\sp_oad_onchip_cc2640r2lp_app_FlashROM_oad_merged.bin
    @set MERGED_HEX=app\FlashROM\Exe\sp_oad_onchip_cc2640r2lp_app_FlashROM_oad_merged.hex
    @set PERSISTENT_BIN=persistent_app\FlashOnly\Exe\sp_oad_onchip_cc2640r2lp_persistent_app_FlashOnly.bin
    @set PERSISTENT_HEX=persistent_app\FlashOnly\Exe\sp_oad_onchip_cc2640r2lp_persistent_app_FlashOnly.hex
    @set APP_HEX=app\FlashROM\Exe\sp_oad_onchip_cc2640r2lp_app_FlashROM.hex
    @set STACK_HEX=stack\FlashROM\Exe\sp_oad_onchip_cc2640r2lp_stack_FlashROM.hex
    @set BIM_HEX=bim_onchip\FlashOnly\Exe\sp_oad_onchip_cc2640r2lp_bim_onchip_FlashOnly.hex

    @set OUT_NAME=peripheralOnchipProduction

    srec_cat.exe %BIM_HEX% -intel %PERSISTENT_HEX% -intel %MERGED_BIN% -bin -o %DEST_PATH%\%OUT_NAME%.hex -intel

    @echo build %OUT_NAME%.hex success!

    Hello User,
    Have you gone through the simplelink academy training for BLE enhanced OAD?
    Are you using the BLE3 stack (i.e. with BLE 4.2 spec features)? BLE5 stack does not support on-chip due to limited flash size.

    Hello User,
    Did you try split image approach where you use srec
    sp_oad_onchip_cc2640r2lp_app_FlashROM_oad.bin
    sp_oad_onchip_cc2640r2lp_stack_FlashROM.hex

    <SREC_LOC>/srec_cat.exe BIM.hex -intel PERSISTENT.hex -intel STACK.hex -intel app_oad.bin -bin -o SUPER.hex -intel

    Did you review this thread:

    Be sure that all projects are using matching configurations (secure vs unsecure). Right-click project -> Build configuration -> set active. Make sure all are either FlashOnly or FlashOnly_unsecure.
