nRF52840 Dongle Programming Tutorial, SES Project/Options menu disable

[david224]

I am trying to setup (Nordic Edition) SES 5.10d for an example to download to the nRF52840 Dongle.

The tutorial* helpfully discusses how to avoid overwriting the MBR and bootloader on the Dongle.

In SES, the Project/Options menu item is disabled, and I cannot find how to enable it, to set :

Update the Preprocessor Definitions:  

```

BOARD_PCA10059

BSP_DEFINES_ONLY

CONFIG_GPIO_AS_PINRESET

FLOAT_ABI_HARD

INITIALIZE_USER_SECTIONS

NO_VTOR_CONFIG

NRF52840_XXAA

```

Adjust the linker configuration:  

```

Linker/Section Placement Macros

FLASH_PH_START=0X0

FLASH_PH_SIZE=0X100000

RAM_PH_START=0X20000000

RAM_PH_SIZE=0X40000

FLASH_START=0X1000

FLASH_SIZE=0XDF000

RAM_START==X20000008

RAM_SIZE=0X3FFF8

```

Any guidance?

Hi,

The instructions in the tutorial are valid for the nRF5 SDK. If you are using the nRF Connect SDK the Options menu will not be enabled, so I assume that is the case?

With nRF connect SDK the general concept is stil valid (the app must start at 0x1000 instead of 0, and leave place for the USB bootloader at the end of the flash), but everything related to how you build your application is completely different and not covered by the tutorial. I most cases the only thing you have to do to build a NCS project for the nRF52840 dongle is to select that the board is nrf52840dongle_nrf52840.

Ah, so I did install the nRF5 SDK for Thread and Zigbee a couple of weeks ago, and likely opened one of those samples, when I set the above parameters.  So today, before I sent my request:

- updated to nRF Connect 3.6

- updated to nRF Connect SDK v1.4.0

Following your response just now I:

- select "Open IDE" from the Toolchain Manager

- then "File/Open nRF Connect SDK Project ...", which opens an nRF Connect Options dialog (very nice)

- choose Blinky (yes the Project/Options is disabled, but if I understand your answer, for my benefit)

- build, locate the zephyr.hex file, flash it to the Dongle with nRF Connect Programmer (since dongle does not have JLink)

- repeat the flash to prove I did not overwrite the MBR and bootloader

This worked. 

Thank you for clarifying that the Nordic SES + nRF Connect SDK correctly configure options for the Dongle.
