Flashing dongle using Visual Studio Code rather than Segger Studio

[HeneryH]

The following instructions are for using Segger Embedded Studio to flash the dongle.

Step 2: Adjust the linker configuration. Set FLASH_START=0x1000 to place the application right above the MBR. You should also set FLASH_SIZE=0xDF000 to make sure that there is room for the bootloader at the end of the flash. Set RAM_START=0x20000008, as the first 8 bytes are used by the MBR for interrupt forwarding and adjust the size accordingly by setting RAM_SIZE=0x3FFF8.

Any advice on how to do the equivalent in Visual Studio Code?  I don't see any similar CONFIG settings in the prj config file.

Hi,

Could you tell me what VS Code version you are using?

Is the partition layout in flash done in a completely different way with Zephyr and Visual Studio ?

I found this file that seems like it might be defining the flash layout

Hi Joseph,

The nRF5 SDK is different from the nRF Connect SDK and VS Code supports the nRF Connect SDK. As mentioned in the Tutorial,
