# 在linux上架設nrf52832的開發環境

**需要下載的工具:**
1. [SDK](https://www.nordicsemi.com/Products/Development-software/nRF5-SDK/Download#infotabs)
2. JLink(https://www.segger.com/downloads/jlink/)
3. arm toolchain:[gcc-arm-none-eabi-4_9-2015q3](https://launchpad.net/gcc-arm-embedded/+download)
4. [nRF Command Line Tools](https://www.nordicsemi.com/Products/Development-tools/nRF-Command-Line-Tools/Download?lang=en#infotabs)

**設定環境:**

1. 解壓縮檔案

sudo unzip  SDK.zip
dpkg -i nrf-command-line-tools_version.deb
sudo tar -xzf ./gcc-arm-none-eabi-4_9-2015q3-20150921-linux.tar.bz2

**以SDK裡面的examples/ble_peripheral/ble_app_uart為例:**
1. 編輯SDK裡面的/components/toolchain/gcc/Makefile.posix檔案。原本的內容如下

GNU_INSTALL_ROOT ?= /usr/local/gcc-arm-none-eabi-7-2018-q2-update/bin/
GNU_VERSION ?= 7.3.1
GNU_PREFIX ?= arm-none-eabi

需將**GNU_INSTALL_ROOT**改為arm toolchain放置位置下的bin目錄。

2. 將JLink底下的**99-jlink.rules**複製到/etc/udev/rule.d目錄底下

cp 99-jlink.rules /etc/udev/rule.d

3. 到ble_app_uart目錄底下命令做編譯和燒錄的動作:

cd /nRF5-SDK/example/ble_peripheral/ble_app_uart
make
make flash

最後程式可以正常運作
