SEGGER and SoftDevice 130 example

[durmaz]

Hello, 

I could not find a way to build S130 examples for nrf51822XXAC via SEGGER. I am getting errors at the build stage. I am using nRF5_SDK_12.3.0_d7731ad. Is there any tutorial?

Thanks in advance.

Hi,

Support for SEGGER came in SDK v14.1.0. Since you're using an older version of the SDK, you must import and convert a Keil project. You can read how to do this in this guide.

Best regards,

Marte

Hi,

I followed the guide for the app below.

/Users/macbook/Downloads/nRF5_SDK_12.3.0_d7731ad/examples/ble_peripheral/ble_app_beacon/pca10028/s130/arm5_no_packs

I got the error below at the build stage.

Hi,

The error is on line 236 in nrf_delay.h, which is the following

#if ( defined(__GNUC__) && (__CORTEX_M == (0x00U) ) )
    ".syntax divided\n"
#endif

So the problem is with the compiler. Did you remember to install the CMSIS-CORE Support Package? If not you can install it by going to Tools > Package Manager, and select and install CMSIS-CORE Support Package. Other things you can check is whether you chose the internal toolchain in the Import Build Configuration window, and that you added and deleted the correct files (delete Cortex_M_Startup.s and add system_nrf51.c and ses_nrf51_startup.s.)

There's also a blog post here that you can follow. The steps are mostly similar to the other guide, but there's some added information in some places.

Best regards,

Marte

Did you ever get to the bottom of this? I am trying to import an old nrf51 Keil project from SDK 12 to compare performance with a newer nrf52 project (SDK 15), and get exactly the same error in the build stage.

I've been following the guide in Marte's first answer, and I've checked that all the suggestions from her second one (internal toolchain, startup files added/removed etc..) - pretty sure I've followed the guide accurately.. any other suggestions much appreciated!

I am getting the same thing

I did install the CMSIS COre. And I followed the guide/tutorial (which is using nrf52.c and the assembly startup for nrf52. I wasn't sure if that was a typo so I went with the nrf51 equivalents.
