Thanks for reply!

Also I found an more specific way to do it from below link

Porting an example from pca10056 to pca10056e (Segger embedded studio)

I downloaded the pca10056e.zip from vidar answer and it works!

Most of these are located in the preprocessor and Linker sections of the SEGGER project settings. The board you set in the preprocessor definitions for example.However, I see you've opened the settings of your main.c file. You should right click the project within SEGGER and open the project options from there, not the File 'main.c' Options.

Best regards,

Simon

Thanks for your reply!
But I checked the document but I need more detail to follow that steps.

Where is project setting changing device section?
And where is c/c+preprocessor setting, preprocessor define

I can't find where it is in my project options section.

Sorry for the basic question and Thank you!

1. Emulation is for testing a project built for an nRf52811 on the nRF52840 DK and using the nRF52840 "as an nRF52811" to test the project in something close to an nRF52811 environment. Emulated projects will also be able to access the DKs LEDs and buttons.

2. For your nRF52840 project you should follow the steps in "Transferring the project to nRF52811 hardware" for your project and it should build for an nRF52811 target afterwards.
For reference, these are the steps in question

Open the example project
In the project settings, change to device "NordicSemiconductor->nRF52811_xxaa".
In the C/C++ preprocessor settings, remove the defines "NRF52" and "NRF52840_XXAA".
Add the preprocessor define "NRF52811_XXAA".
In the linker script settings, adjust the linker script to match the maximum RAM and flash size of nRF52811.
- ROM END: 0x2FFFF
- RAM END: 0x20005FFF
Remove the following files from the project: <compiler>_startup_nrf52.s and system_nrf52.c.
Add the following files to the project: <compiler>_startup_nrf52811.s and system_nrf52811.c.

After that, if you have connected the nRF52811 custom board as described in the link above, the DK should automatically detect the nR52811 and flash the board with the correct firmware (as long as the nRF52811 is also running on 3V, which is the voltage supported by the debugger onboard the DK.

Best regards,

Simon
