輕輕鬆鬆，Go 真方便。

GOOS=linux GOARCH=mipsle go build Web.go
#Web.go 取代為你自己要編譯的code
#Linkit 7688 為 mipsle

GOOS=linux GOARCH=mipsle go build Web.go

#Web.go 取代為你自己要編譯的code

#Linkit 7688 為 mipsle

好，問題又來了，要編譯有cgo的go檔案時，需要將相對應的gcc安裝好並且設定編譯成static
因此首先，需要在自己的Ubuntu環境內先安裝相對應的gcc工具

#7688 為mipsle版本
sudo apt-get install gcc-5-mipsel-linux-gnu g++-5-mipsel-linux-gnu libc6-dev-mipsel-cross
#參考至 xgo docker:https://github.com/karalabe/xgo/blob/master/docker/base/Dockerfile

#7688 為mipsle版本

sudo apt-get install gcc-5-mipsel-linux-gnu g++-5-mipsel-linux-gnu libc6-dev-mipsel-cross

#參考至 xgo docker:https://github.com/karalabe/xgo/blob/master/docker/base/Dockerfile

安裝好後，即可下指令compile你含有cgo的程式了，
這邊我是compile go sqlite3的example

CGO_ENABLED=1 GOOS=linux GOARCH=mipsle CC=mipsel-linux-gnu-gcc CXX=mipsel-linux-gnu-g++ \
go build -v -ldflags "-linkmode external -extldflags -static" simple.go
#編譯好後，可以用file檢查檔案是否為static
#simple: ELF 32-bit LSB executable, MIPS, MIPS32 version 1, statically linked, for GNU/Linux 3.2.0, BuildID[sha1]=19e55e478df9906f05ba1963671d58b90acbab13, not stripped
#顯示此訊息代表成功

CGO_ENABLED=1 GOOS=linux GOARCH=mipsle CC=mipsel-linux-gnu-gcc CXX=mipsel-linux-gnu-g++ \

go build -v -ldflags "-linkmode external -extldflags -static" simple.go

#編譯好後，可以用file檢查檔案是否為static

#simple: ELF 32-bit LSB executable, MIPS, MIPS32 version 1, statically linked, for GNU/Linux 3.2.0, BuildID[sha1]=19e55e478df9906f05ba1963671d58b90acbab13, not stripped

首先下載Linkit 7688 能用的執行檔並且解壓縮後利用scp 傳至7688內
https://github.com/fatedier/frp/releases
7688用的是mipsle的版本。

scp /home/notbeloser/Downloads/frp_0.16.0_linux_mipsle/frpc* root@mylinkit.local:/root

1	scp /home/notbeloser/Downloads/frp_0.16.0_linux_mipsle/frpc* root@mylinkit.local:/root

完成後配置frpc.ini
啟動測試

chmod +x frpc*
~/frpc -c ~/frpc.ini
#正常來說 會收到以下訊息 代表成功

chmod +x frpc*

~/frpc -c ~/frpc.ini

#正常來說會收到以下訊息代表成功

配置開機自啟動
需要先安裝screen

opkg update
opkg install screen
#配置rc.local
sed -i '/exit 0/i\sleep 10 && screen -dmS frpc /root/frpc -c /root/frpc.ini' /etc/rc.local

opkg update

opkg install screen

#配置rc.local

sed -i '/exit 0/i\sleep 10 && screen -dmS frpc /root/frpc -c /root/frpc.ini' /etc/rc.local

配置好後 rc.local裡面會長這樣

# Put your custom commands here that should be executed once
# the system init finished. By default this file does nothing.
#!/bin/bash
sleep 10 && screen -dmS frpc /root/frpc -c /root/frpc.ini
exit 0

# Put your custom commands here that should be executed once

# the system init finished. By default this file does nothing.

#!/bin/bash

sleep 10 && screen -dmS frpc /root/frpc -c /root/frpc.ini

exit 0

這時就可以reboot測試

#開機完成後
screen -r

1 2	#開機完成後 screen -r

有跳出frpc的log的話，表示開機運行成功！

因為

mbed跟Arduino，都是算不錯好上手簡單開發的工具。
但是用習慣Arduino語法的我們，還是覺得使用Arduino開發比較簡單。
且有許多熟悉的Library可以直接使用，方便許多。
所以這邊來講裝Arduino的流程。

安裝環境

Ubuntu 16.04
我就假設已經你們自己都裝好Arduino IDE了。
依照arduino-nRF5所述步驟
首先就先安裝Ubuntu相關所需套件

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get -y install libc6:i386 libstdc++6:i386 libncurses5:i386 libudev1:i386

sudo dpkg --add-architecture i386

sudo apt-get update

sudo apt-get -y install libc6:i386 libstdc++6:i386 libncurses5:i386 libudev1:i386

開始安裝Arduino的部份吧
進IDE後–>檔案–>偏好設定–>額外的開發板管理員網址

https://sandeepmistry.github.io/arduino-nRF5/package_nRF5_boards_index.json

1	https://sandeepmistry.github.io/arduino-nRF5/package_nRF5_boards_index.json

在工具—>開發板最上方有個開發板管理員，點選進入。
搜尋nRF5 即可找到剛剛我們加入的開發板，點選安裝。
安裝完成後，即可到開發板區域選擇nRF51
這邊還有一點要用藍芽功能的話
可以選擇S130 SoftDevice or S132 SoftDevice
功能我也還沒看，有興趣可以自己去看原廠Paper
要安裝SoftDevice的話要Follow以下步驟

cd ~/Arduino
mkdir tools
mkdir tools/nRF5FlashSoftDevice
mkdir tools/nRF5FlashSoftDevice/tool/
cd tools/nRF5FlashSoftDevice/tool/
wget https://github.com/sandeepmistry/arduino-nRF5/releases/download/tools/nRF5FlashSoftDevice.jar

cd ~/Arduino

mkdir tools

mkdir tools/nRF5FlashSoftDevice

mkdir tools/nRF5FlashSoftDevice/tool/

cd tools/nRF5FlashSoftDevice/tool/

wget https://github.com/sandeepmistry/arduino-nRF5/releases/download/tools/nRF5FlashSoftDevice.jar

重開Arudino IDE
選擇開發板-我自己的是WaveShare BLE400
SoftDevice S130
燒錄器 CMSIS-DAP
工具 -> nRF5 Flash SoftDevice

但在這邊燒錄SoftDevice時出了點問題，以下是吐出來的錯誤訊息

/home/notbeloser/.arduino15/packages/sandeepmistry/tools/openocd/0.10.0-dev.nrf5/bin/openocd -d2 -f interface/cmsis-dap.cfg -c ; -f target/nrf51.cfg -c init; halt; nrf51 mass_erase; program {{/home/notbeloser/.arduino15/packages/sandeepmistry/hardware/nRF5/0.5.1/cores/nRF5/SDK/components/softdevice/s130/hex/s130_nrf51_2.0.1_softdevice.hex}} verify reset; shutdown;

這邊是出在權限不足的問題，因此要把Arduino用su的身份執行。

不過，先用上一篇編譯好的OpenOCD做燒錄試試看吧，參考他吐出來的指令下。

sudo openocd -f interface/cmsis-dap.cfg -f target/nrf51.cfg
#call a new terminal
telnet localhost 4444
> init
> halt
> nrf51 mass_erase
> program /home/notbeloser/.arduino15/packages/sandeepmistry/hardware/nRF5/0.5.1/cores/nRF5/SDK/components/softdevice/s130/hex/s130_nrf51_2.0.1_softdevice.hex verify
> reset
> shutdown

sudo openocd -f interface/cmsis-dap.cfg -f target/nrf51.cfg

#call a new terminal

telnet localhost 4444

> init

> halt

> nrf51 mass_erase

> program /home/notbeloser/.arduino15/packages/sandeepmistry/hardware/nRF5/0.5.1/cores/nRF5/SDK/components/softdevice/s130/hex/s130_nrf51_2.0.1_softdevice.hex verify

> reset

> shutdown

這邊要解決OpenOCD的燒錄問題有兩個方法

使用Root權限開啟Arduino IDE
使CMSIS-DAP使用時不須Root

這邊選擇第二個方案，因為我不只會在Arduino IDE內開發，也在Eclipse內。
從StackOverFlow尋找到解法

sudo nano /etc/udev/rules.d/98-openocd.rules
#加入以下內容到檔案
ACTION!="add|change", GOTO="openocd_rules_end"
SUBSYSTEM!="usb|tty|hidraw", GOTO="openocd_rules_end"
ATTRS{product}=="*CMSIS-DAP*", MODE="664", GROUP="plugdev"                                                                                                                                                                                
LABEL="openocd_rules_end
#離開並存檔
sudo udevadm control --reload

sudo nano /etc/udev/rules.d/98-openocd.rules

#加入以下內容到檔案

ACTION!="add|change", GOTO="openocd_rules_end"

SUBSYSTEM!="usb|tty|hidraw", GOTO="openocd_rules_end"

ATTRS{product}=="*CMSIS-DAP*", MODE="664", GROUP="plugdev"

LABEL="openocd_rules_end

#離開並存檔

sudo udevadm control --reload

可以透過Arduino成功燒錄了！

安裝好SoftDevice之後，還需要安裝一個BLE的Library，不然會開發的很痛苦。

在Arduino-IDE內，選擇管理程式庫
搜尋BLEPeripheral，並安裝。

此時就可以著手開發藍芽了～

前言

在開發nRF51822前，當然要佈置他的開發環境
沒有錢買Keil C的我，只能用open source的東西自己架
安裝環境:Ubuntu 16.04

首先

要先檢查相關工具的版本

You'll also need:

- make
- libtool
- pkg-config >= 0.23 (or compatible)

Additionally, for building from git:

- autoconf >= 2.64
- automake >= 1.14
- texinfo

USB-based adapters depend on libusb-1.0 and some older drivers require
libusb-0.1 or libusb-compat-0.1. A compatible implementation, such as
FreeBSD's, additionally needs the corresponding .pc files.

USB-Blaster, ASIX Presto and OpenJTAG interface adapter
drivers need:
  - libftdi: http://www.intra2net.com/en/developer/libftdi/index.php

CMSIS-DAP support needs HIDAPI library.

- texinfo

drivers need:

- libftdi: http://www.intra2net.com/en/developer/libftdi/index.php

CMSIS-DAP support needs HIDAPI library.

為了要可以支援CMSIS-DAP這個Open Source的燒錄器，需要安裝HID library和相關Library。

sudo apt-get install libudev-dev libusb-1.0-0-dev libfox-1.6-dev
sudo apt-get install libhidapi-dev

1 2	sudo apt-get install libudev-dev libusb-1.0-0-dev libfox-1.6-dev sudo apt-get install libhidapi-dev

之後去clone OpenOCD&開始編譯

git clone https://github.com/riscv/riscv-openocd openocd
./bootstrap#(when building from the git repository)
./configure#[options]
make
sudo make install

git clone https://github.com/riscv/riscv-openocd openocd

./bootstrap#(when building from the git repository)

./configure#[options]

make

sudo make install

安裝好之後就可以透過openOCD上傳第一支LED閃爍的程式測試了

sudo openocd -f interface/cmsis-dap.cfg -f/target/nrf51.cfg

1	sudo openocd -f interface/cmsis-dap.cfg -f/target/nrf51.cfg

成功的話，會跑出以下字串

這時候就可以透過mbed先編譯一個 LED Blinky，下載Hex測試。

telnet localhost 4444#連接openOCD Debug port
>program /home/notbeloser/Downloads/mbed_blinky_NRF51822.hex verify
>reset

telnet localhost 4444#連接openOCD Debug port

>program /home/notbeloser/Downloads/mbed_blinky_NRF51822.hex verify

>reset

LED若是開始閃爍，代表成功！
