Converting a standard PCA10040 project to an emulated project

[Rohit]

Hello all,

I am using the NRF52810 board with SDK 14.2

I wanted to convert pca10040 to pca10040e file of buttonless dfu and secure bootloader.

I have gone through this link https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.2.0%2Findex.html

                                              Software Development Kit > Previous versions of nRF5 SDK > nRF5 SDK v15.2.0 > User Guides

I have followed all steps as per given link but after compiling i am getting following error

#error "Compiler generates FPU instructions for a device without an FPU (check __FPU_PRESENT)" in segger IDE

I have followed this link also but i have not getting anything..

https://devzone.nordicsemi.com/f/nordic-q-a/20825/fatal-error-pe035-error-directive-compiler-generates-fpu-instructions-for-a-device-without-an-fpu-check-__fpu_present

Can anyone provide proper procedure - How to solve this error?

or pca10040e for buttonless dfu file is available ?

Regards,

Rohit

HI Rohit, 

we do have pca10040e examples for the Secure Bootloader in SDK v15.2.0 so I would recommend to use that instead of modifying the pca10040 example in SDK v14.2.0. Generally, I would recommend using the lastest SDK. 

However, if moving to a newer SDK is not an option, then you need to set the FPU options for the SES project correctly, i.e. 

Best regards
