Installation and configuration of the Openwrt Image on Linkit 7688 and 7688 Duo

2017-07-15 admin

After you have attached to the board the support devices, as specified in the previous article

Linkit 7688 Duo Connections

and built the image

OpenWrt building for Linkit 7688 and 7688 Duo

we upload the image to the device.

Following the documentation availble at the link

Update the firmware with a USB drive

to update the firmware copy the openwrt-ramips-mt7688-LinkIt7688-squashfs-sysupgrade.bin file to the root directory of a FAT32 USB drive and rename it as lks7688.img.

Attach, now, the USB drive to the HOST port of the board with an OTG cable and follow the steps

Press and hold the on-board WiFi button.
Press the MPU reset button once, while holding the WiFi button
Keep holding the WiFi button for about 5 seconds. Do not release until the orange LED for WiFi is off. DO NOT press the WiFi button longer than 20s or it will upgrade the bootloader.
The device will automatically reboot after firmware update is complete.

You can control the operation via the USB TTL serial connected to the PC and activated on the enabled Com port with the following settings

Port: Enabled COM
Speed: 57600
Data Bits: 8
Stop Bits: 1
Parity: None
Flow Control: XON/XOFF

Use, for example, putty to connect, press Enter if the screen is not active, and check the steps the system is runnig when upgrading

When the orange LED starts blinking at a lower frequency the card is ready to be used.

Search for visible access points from your PC and you should find an access point named LinkIT_Smart_7688_xxxxxx, where xxxxxx identifies the specific device.

Connect to this Access Point and access via browser at 192.168.100.1 or at mylinkit.local if you have satisfied the prerequisites

Getting started

Enter a password and access the next step

Select OpenWrt for Advanced Configuration

Set the password on OpenWrt

entering it twice

At this point, the system is configured as an Access Point. In our case, we wanted to set the Link 7688 Duo as a client of an Access Point with WPA2 security. To get this setting, if you have a visible network, go to the Network section of the main web console interface

set the values for the Access Point and restart the system

If the Access Point is hidden, you should set the parameters directly in the configuration files in /etc /config.

Connect with putty to the previously connected USB TTL serial and run the commands for Access Points with wpa2 security

uci set wireless.sta.ssid=ACCESS POINT
uci set wireless.sta.key=password access point
uci set wireless.sta.encryption=psk2

uci set wireless.sta.ssid=ACCESS POINT

uci set wireless.sta.key=password access point

uci set wireless.sta.encryption=psk2

Save the settings

uci commit

1	uci commit

and activate the new configuration

wifi_mode sta

1	wifi_mode sta

Check the /etc/config/wireless file; you should see the addition of a new section, config wifi-iface ‘ap’, to connect the board to the access point

root@mylinkit:/etc/config# cat wireless

config wifi-device 'radio0'
        option type 'ralink'
        option variant 'mt7628'
        option country 'TW'
        option hwmode '11g'
        option htmode 'HT40'
        option channel 'auto'
        option disabled '0'
        option linkit_mode 'sta'

config wifi-iface 'ap'
        option device 'radio0'
        option mode 'ap'
        option network 'lan'
        option ifname 'ra0'
        option encryption 'none'
        option ssid 'LinkIt_Smart_7688_1C4775'
        option seq '1'

config wifi-iface 'sta'
        option device 'radio0'
        option mode 'sta'
        option network 'wan'
        option ifname 'apcli0'
        option led 'mediatek:orange:wifi'
        option ssid 'AccessPoint'
        option key 'password'
        option encryption 'psk2'

root@mylinkit:/etc/config#

root@mylinkit:/etc/config# cat wireless

config wifi-device 'radio0'

option type 'ralink'

option variant 'mt7628'

option country 'TW'

option hwmode '11g'

option htmode 'HT40'

option channel 'auto'

option disabled '0'

option linkit_mode 'sta'

config wifi-iface 'ap'

option device 'radio0'

option mode 'ap'

option network 'lan'

option ifname 'ra0'

option encryption 'none'

option ssid 'LinkIt_Smart_7688_1C4775'

option seq '1'

config wifi-iface 'sta'

option device 'radio0'

option mode 'sta'

option network 'wan'

option ifname 'apcli0'

option led 'mediatek:orange:wifi'

option ssid 'AccessPoint'

option key 'password'

option encryption 'psk2'

root@mylinkit:/etc/config#

Now the card acts as a client and you can access it using the address released by the Access Point or by name as indicated by the documentation

LEDE building for Linkit 7688 Duo

2017-07-09 admin

After OpenWrt image building using the Mediatek SDK

OpenWrt building for Linkit 7688 and 7688 Duo

this article describes how to generate a LEDE image for the Linkit 7688 Duo.

The steps on how to compile LEDE are available at the link

LEDE Building

Clone the code from the github in a shell command window, always from the Linkit folder

cd
cd Linkit

1 2	cd cd Linkit

run

git clone https://git.lede-project.org/source.git Lede

1	git clone https://git.lede-project.org/source.git Lede

Create the src folder under Linkit and extract the compressed file

Feed for Linkit

This feed was created from Mediatek one, eliminating the binary drivers dependency.

Copy the file to the src folder and uncompress it

sviluppo@debian:~/Linkit/src$ ls
linkit.tar.gz
sviluppo@debian:~/Linkit/src$ tar -zxvf linkit.tar.gz

sviluppo@debian:~/Linkit/src$ ls

linkit.tar.gz

sviluppo@debian:~/Linkit/src$ tar -zxvf linkit.tar.gz

sviluppo@debian:~/Linkit/src$ ls
linkit  linkit.tar.gz
sviluppo@debian:~/Linkit/src$

sviluppo@debian:~/Linkit/src$ ls

linkit linkit.tar.gz

sviluppo@debian:~/Linkit/src$

Go to the Lede folder and copy the feeds.conf.default file as feeds.conf

cd 
cd Linkit/Lede
cp feeds.conf.default feeds.conf

cd Linkit/Lede

cp feeds.conf.default feeds.conf

Run

echo src-cpy  linkit ~/Linkit/src/linkit >> feeds.conf

1	echo src-cpy linkit ~/Linkit/src/linkit >> feeds.conf

Update the feeds for the packages

./scripts/feeds update

1	./scripts/feeds update

One way to fix the problem is the following.

Go to the /home/sviluppo/Linkit/openwrt/feeds/linkit/mtk-sdk-wifi/wifi_binary/ folder and copy the files for our kernel version

cp mt_wifi.ko_3.18.44 mt_wifi.ko_3.18.45
cp mt_wifi.ko_3.18.44_all  mt_wifi.ko_3.18.45_all

1 2	cp mt_wifi.ko_3.18.44 mt_wifi.ko_3.18.45 cp mt_wifi.ko_3.18.44_all mt_wifi.ko_3.18.45_all

Rerun the building. At the end of the process the generated file is available in the bin/ramips folder

The built firmware is available here

OpenWrt Linkit 7688 and 7688 Duo Image

WARNING: The image installation on the device is at your own risk. We accept no responsibility if the installation leads to malfunction or block of the device.

If you upgrade the board using an usb flah drive, you need to rename the openwrt-ramips-mt7688-LinkIt7688-squashfs-sysupgrade.bin file in lks7688.img.

The image kernel for this building is 3.18_45; If you want to use a recent kernel, you must use the opensource drivers available for the board; in the case of the Linkit 7688 Duo card, in our possession, we can rebuild the image using the Realtek rt76 drivers for the wireless network adapter and add the additional components for the Atmel MCU using LEDE, an OpenWrt fork

LEDE Project

In the next article you will build a LEDE image for the Linkit 7688 Duo board. For the Linkit 7688 board at this time, the mraa libraries, used to interface the periphals, are not yet compatible with the latest version of LEDE and the functionality of the image is limited. There may be also bugs in the wireless card opensource drivers, which hopefully are solved in the refinement of these drivers.

The two boards share the same Microprocessor (MPU MT7688AN), but in the case of the Linkit 7688 Duo this MPU is supported by the Atmel Microcontroller (MCU ATmega32U4) for device management.

The interfacing schemes are shown with peripherals in the two cases below

The operating system used for both bords is OpenWrt, but the peripherals management is different. While in the case of Linkit 7688 we only rely on MPUs and specific libraries to manage the interfacing with peripherals, for the Linkit 7688 Duo the ATmega32U4 microcontroller manages the peripherals. The programming of the ATmega32U4 is executed with the Arduino IDE by adding the Linkit 7688 Duo board support into the tool as specified at the following link

Arduino Ide support for Linkit 7688 Duo

At the followning link there is the Mediatek documentation for the two boards

Linkit 7688 and 7688 Duo Resources

The following pages show how the two boards can interact with the various peripherals

Linkit 7688 peripherals

Linkit 7688 Duo peripherals

At the Mediatek site, there are also examples to follow step by step to test the various features of the development boards.

Access now the Freeboard dashboard and add the links to the temperature and humidity topics, the gauges and timeseries mesauring the values in real time and in a specific range of time . Here are some settings:

Datasource

Gauge

Timeseries

Chrome/Chromium browser allows to save the settings in a json file. This settings can be loaded locally or loaded from the web server, saving for example the dashboard.json file in /var/www/html/freeboard, with the url

http://beaglebone.local/freeboard/index.html?load=dashboard.json

1	http://beaglebone.local/freeboard/index.html?load=dashboard.json

The image shows the Freeboad interface with various widgets showing the status and timeseries of the ESP8266 relay and sensors

In these series of articles we configured the envinronment to access the Beaglebone using the beaglebone.local/beaglebone alias

Debian sd card setup for Beaglebone Black

but you can use anyway the Beaglebone IP tho access the services provided by the board.

In the next article we’ll treat the Mqtt Android client

Libreelec8 in OrangePI PC

2017-04-13 admin

This article describes the steps that I ran to prepare a first version of Libreelec 8 in Orange PI PC cards and other H3 socs.

Starting from the Debian development envinronment, with its installed packages, already used for the compilation of OpenELEC 7

Openelec compilation for Orange PI PC

we proceed to build an Libreelec 8 image.

We started as basis from the work done for Openelec 7 and Libreelec 7 available on the two github repositories

H3 Openelec 7 Github

H3 Libreelec 7 Github

sviluppo@debian8:~/orangepi$ mkdir libreelec
sviluppo@debian8:~/orangepi$ cd libreelec
sviluppo@debian8:~/orangepi/libreelec$

sviluppo@debian8:~/orangepi$ mkdir libreelec

sviluppo@debian8:~/orangepi$ cd libreelec

sviluppo@debian8:~/orangepi/libreelec$

Clone the Libreelec8 github

git clone -b libreelec-8.0 https://github.com/LibreELEC/LibreELEC.tv.git libreelec-8.0

1	git clone -b libreelec-8.0 https://github.com/LibreELEC/LibreELEC.tv.git libreelec-8.0

The patches have been created for a specific version of the commit, so we align our github clone to that version

cd libreelec-8.0
git checkout 745f6790ec0456aa8478fff5360107c148ea5204

1 2	cd libreelec-8.0 git checkout 745f6790ec0456aa8478fff5360107c148ea5204

Download from the following link the patches, the H3 project and other stuff
