Hi Nilesh,

you can generate firmware images for the Secure Bootloader using our nrfutil tool, which is available here on GitHub.

Install instructions and examples on how to generate the firmware images are given in the READM.md file.

Best regards

Hello Sir,

Thank you for your valuable response.

As per your suggestion, i am trying to update hex file of ble_app_blinky_c program with SDK11. And I have done successfully OTA update file in my nRF51 Board.

But as of Now, every time i need to upload softdevice & bootloader file using nrfgo studio then after its updates hex file.

So, Is it possible bootloader and hex file using keil? Any additional changes required into the program?

Thanks
