Program the BLE soft device of nRF51822 (Linux)

If you haven't read the tutorial "How to develop for nRF51822 on Linux using GCC", go back.

This page explains how to program the Bluetooth Low Energy soft device to the nRF51822 using the Linux command line.

1. From the http://www.nordicsemi.com/ web site, download the newest version of the nRF51822-SD (BLE soft device). This is possible after registering the evaluation kit.
   
   
2. When you have the s110_nrf51822_5.0.0_softdevice.hex file, you need to convert it to two .bin files by running these commands:

   /opt/arm-2012.09/bin/arm-none-eabi-objcopy -I ihex  -O binary --only-section .sec3 s110_nrf51822_5.0.0_softdevice.hex s110_uicr.bin
   /opt/arm-2012.09/bin/arm-none-eabi-objcopy -I ihex  -O binary --remove-section .sec3 s110_nrf51822_5.0.0_softdevice.hex s110_mainpart.bin
   

   (There may be a newer version of the SD when you read this)
   
   
3. Start StartJLinkExe.sh (you can start it with ./segger/segger.sh from the "simple-nrf51822-linux" project directory. See here) and execute these commands:

   r
   w4 4001e504 1
   loadbin s110_uicr.bin 0x10001000
   loadbin s110_mainpart.bin 0
   r
   g
   

   The soft-device is now installed on the device!!! (if you don't get any error messages) If it doesn't work, try to erase the flash first (see below).
   
   

Erase the flash:

w4 4001e504 2
w4 4001e50c 1
w4 4001e514 1
r
