how to make and flash hex files?

[srony]

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?

I learned from a related case, below command used to flash application.

nrfjprog -f nrf52 --program your_application.hex --sectorerase --reset

it is for linux IDE, right? what about SES?

besides I still need to know how to flash softdevice only? and how to generate all-in-one hex file and flash it?

Thanks and Regards,

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 .

Thanks Hung. 

I just use SES download an intel hex file.

Now it is clear. I believe my application doesn't work.

Just now I installed nRF-Command-Line-Tools on windows. It works well.

Thanks for your explanations.
