RE: OTA Automatically Reset and Start the Application After Flashing a Merged Hex File

Hello,

By design, the chip is not reset automatically when you program something to it. There are many reasons for this, for example that you may want to program more hex files without a reset in between (e.g. when working with a bootloader, if you reset it after flashing the bootloader, it will create bootloader settings partitions, but you may want to program your own bootloader settings from a hex file before you reset the device).

However, you can attach the argument --reset at the end of your program command, like this:

nrfjprog --program final_dongle.hex --verify --reset

This will program the device, and reset it when it is done verifying the hex file on the target.

Does that work for you?

Best regards,

Edvin
