Writing programs using nRF Connect Programmer

[komuro]

I wrote a program for nRF51822 and compiled it with keil.
The app, boot, and sdk are combined and written to the chip.
However, if I write using nRF Connect Programmer, it works without boot.
Why does it work without boot when writing with nRF Connect Programmer?
*When writing without boot using a tool other than nRF Connect Programmer, it did not work.

Hello,

Please check if the "Reset and Run" checbox is ticked in your debugger settings.

Thank you for confirming.
In the debugger settings, the "Reset and Run" checkbox was checked.
Is this check related to the fact that it works with nRF Connect Programmer and does not work with tools other than nRF Connect Programmer?

I think I misunderstood your question, I thought the problem was that program execution didn't start (boot) after loading the FW from Keil. What other tools do you use for programming?

[komuro]

Thank you for your confirmation.
The other tool was confirmed by another company, so we don't know what they were using (we'll add it as soon as we know).
The following is a summary of the situation.

	app + sdk + boot	app + sdk
nRF Connect Programmer	OK	OK
Another Tool	OK	NG

It was confirmed.
NETIMPRESS AF430 is used for writing.
SWD Adapter AZ442 is also used.

Ok, so if I've understood this correctly, the device works ok if you don't program the bootloader, right? If so, is it possible that they may still be writing the bootloader address to the UICR @ 0x10001014 even if the bootloader is not present? 

The master boot record will assume that a bootloader is present if this register is set as explained here: Bootloader
