Harvester 1.7.0 Custom Routes

-

Because Harvester is an immutable Linux distribution, changes in terminal will be discarded when the server is restarted. Additional config should be written in specific configuration files so it can persist between reboot, including custom route. In previous Harvester version, the configuration can be added in the file inside /oem/ folder. But for version 1.7.0, it should be added using nmcli. Below is the example to add custom route to 192.168.1.0/24 via interface 192.168.0.1

nmcli connection modify vlan-mgmt +ipv4.routes "192.168.1.0/24 192.168.0.1"

VGA out for cubieboard

-
Image
Because my TV is used mainly for watching. I need an alternative display output for my cubieboard. The easiest way is using CVBS pin, and attach it to RCA jack to connect to video input. But I don't have another display with video in, so I need to built VGA out for the cubieboard. Component needed : 3 x 75 ohm low-tolerance resistors. 1 x 74ACT08D quad AND gate. 2 x bat54s SCHOTTKY diodes (I can't find it in my local store, so I change it with 4 x bat85s or any SCHOTTKY diodes). 1 x 100 nF low-tolerance capasitor. 1 x VGA DB15 connector.

Video and Audio Streaming from A20SOM-EVB using crtmpserver

-
To stream video and audio from A20SOM-EVB, ffmpeg and crtmpserver are used. FFmpeg is used to encode the video and audio from A20SOM-EVB csi-camera and mic-in and then feed the stream to crtmpserver. Crtmpserver act as streaming server to provide rtmp stream for flash player, or rtsp stream for video player such as videolan. If the csi camera is not yet functioning on the default debian distro, please follow my previous article how to enable csi-camera on A20SOM-EVB .

enable csi camera on A20-SOM EVB

-
The csi camera on the debian image with kernel 3.4.79+ from olimex doesn't work. To make it works, we need to change the configuration in script.bin and /etc/modules. We must convert script.bin to script.fex using bin2fex tools to change the configuration. olimex@a20-Lime2-SOM:~$ bin2fex script.bin script.fex We will have script.fex file after that command. Open the file and change the value as below: ... [csi0_para] csi_used = 1 ... Convert back script.fex to script.bin. olimex@a20-Lime2-SOM:~$ fex2bin script.fex script.bin Add the following value in the /etc/modules file: gt2005 sun4i_csi0 i2c_addr=0x78 ccm="gt2005" After that, we can reboot the board. Wait a couple second, and voila...the csi camera will now work. But there is still error message from the kernel log as follow: [CSI_ERR]input index invalid! Nevertheless, the csi camera works fine, if someone know how to solve this error, please let me know.
