nrf52810 + secure bootloader + s112 + BLE APP

Hello,

I am facing some troubles generating and flashing a complete hex file using the Nordic command line utils. Below, I will explain my scenario:

  • Secure bootloader pca10040e_s112_ble
  • BLE App ble_app_ias_c_pca10040e_s112
  • Softdevice s112 7.2.0
  • nRF5 SDK 17.1.0

The HW environment is as follows:

  • nrf52832 EVK working as nrf52810

I did not change nothing of the examples except of the dfu_public_key.c that I am using one that I generated in order to have also the priv.key. 

The commands that I am performing are:

nrfutil.exe settings generate --family NRF52810 --application ble_app_ias_c_pca10040e_s112.hex --application-version 2 --bootloader-version 2 --bl-settings-version 2 settings_app.hex

mergehex.exe -m secure_bootloader_ble_s112_pca10040e.hex s112_nrf52_7.2.0_softdevice.hex -o boot_soft.hex

mergehex.exe -m boot_soft.hex settings_app.hex -o boot_soft_sett.hex

mergehex.exe -m ble_app_ias_c_pca10040e_s112.hex boot_soft_sett.hex -o app.hex

nrfjprog.exe --family nrf52 --eraseall

nrfjprog.exe --reset --family NRF52 --program app.hex

Once the EVK is flashed, I do not see any output, only LED5 blinking.

On the other side, if I flash the same binaries using the NRF Programmer, I can see the BLE App running and everything is fine.

Any sugestion about the commands? 

Many thanks in advanced,

Javier

  • Hello,

    I want to shed ligth on this topic before investigating more about flashing process. I have changed the app, just to give a try with an easy example (ble_app_blinky) and it is working.... at least I see the device on the BLE network but it rejects the connection.

    What I guess now is that there is a memory problem. Because the example that I used before was more complete. Which is the RAM configuration for nrf52810 device using s112? I saw in this topic Adjustment of RAM and Flash memory that SD uses:

    Therefore, which is the proper configuration for memory RAM for APP-BLE and s112?

    Regards,
