how to make and flash hex files?

Question

I used armgcc and built out nrf52810_xxaa.hex (file size 60656) in 
 nRF5_SDK_17.0.0_9d13099/examples/ble_peripheral/ble_app_beacon/pca10040e/s112/armgcc/_build 
 
 I used SES download it into board successfully, no error prompt. but the board does not work. 
 
 I used SES download ble_app_beacon_pca10040e_s112.hex (file size 334764) in 
 nRF5_SDK_17.0.0_9d13099/examples/ble_peripheral/ble_app_beacon/hex 
 the board works fine. 
 
 So I want to know, 
 1. How can I generate the hex file like the ble_app_beacon_pca10040e_s112.hex on Linux IDE? 
 2. Can I flash the nrf52810_xxaa.hex only? How to do that?

Hi, Could you let me know what exactly you did on " I used SES download it into board successfully, no error prompt. but the board does not work." ? How did you import it to SES ? 
 For flashing the application I would suggest to go through the following: 
 - First try to do an erase all: nrfjprog --eraseall 
 - Then try to flash an application that doesn't require softdevice, for example blinky: \examples\peripheral\blinky\pca10040e\blank\armgcc 
 - Then flash the softdevice .hex file. You can find the softdevice .hex files in \components\softdevice 
 - After that flash the application that require softdevice, for example the one you built in examples/ble_peripheral/ble_app_beacon/pca10040e/s112/armgcc/_build. Use --sectorerase, don't use --chiperase. 
 The hex file we provide in /examples/ble_peripheral/ble_app_beacon/hex is a merged hex file. You can merge softdevice hex file to application hex file if you want, just use mergehex.exe. It's provided with the nrf command line tools .
