Nordic nRF51 DK on Mac with CrossWorks

On OSX with Rowley Associates CrossWorks what are the steps needed to compile and run a simple BLE UART sample code for Nordic nRF51 DK to an iPhone.

I found iOS and Android code here and am comfortable with that part: https://www.nordicsemi.com/Products/nRFready-Demo-APPS

But I am not sure how to get the toolchain setup and running on the nRF51 board. I've seen some directions for SDK 6.x but can't find anything for SDK 7.x.

Solution

  • This is how I got it to work:

    1. Setup "nRF51 SDK"

    2. unzip "nRF51_SDK_8.0.0_5fc2c3a_packs/nRF_SoftDevice_S110/NordicSemiconductor.nRF_SoftDevice_S110.8.0.0.pack"

    3. Load "$nRF51_SDK_8.0.0_5fc2c3a/components/softdevice/s110/hex/s110_softdevice.hex" on nRF51 with RKNRFGO.app

    4. In CrossWorks File->Import Project and select "$nRF51_SDK_8.0.0_5fc2c3a/examples/ble_peripheral/ble_app_uart"

    5.in "Select Template" select "nRF51_EXE - ..."template list

    1. Remove "retarget.c" from project (it is easiest if you build now so you get the error)

    2. Select Project Item-> "Project 'nrf51422_xxac_s110'" in project explorer

    3. In "Properties Window" scroll down to "Linker Options" and set "Section Placement Macros" to:

      FLASH_START=0x18000

      RAM_START=0x20002000

    Also make sure Properties Window->Target Loader Options->Can Erase All is set to "No"

    1. Select Build->nrf51422_xxac_s110...

    9.5 Select Target -> Connect -> SEGGER J-LINK

    1. Select Debug->Go

    Now apps can connect to the nRF51 DK board
