help regarding using VNC server on beagleboard-xm

sach kharude

Hi,

I have ported android gingerbread on beagleboard-xm. I want to use vnc server on beagleboard-xm.

I think usb over ethernet is enabled on this gingerbread image that is i am using, because when i type command through minicom it shows usb0 instead of eth0.

I have following doubts :

1. How to configure ethernet over usb ?

2. in my college there are proxy settings for internet with username and password, so how to configure net ?

3. Which cable should i use usb-mini-A or usb-mini-B ?

4. is there direct vncserver application or i have to cross compile it ? Please provide me links for vncserver .

Hi,

#1.

http://processors.wiki.ti.com/index.php/TI-Android-GingerBread-2.3.4-DevKit-2.1_UserGuide#adb_over_USB_Ethernet_.28Ethernet_over_USB.29

#2.

http://processors.wiki.ti.com/index.php/TI-Android-GingerBread-2.3.4-DevKit-2.1_UserGuide#Browser_Configuration

3. USB mini-B

4. For VNC server do the following

$ cd <android source path>/external

$ git lone git://gitorious.org/rowboat/droid-vnc-server.git

$ cd droid-vnc-server/jni

$ source <android source path>/build/envsetup.sh

$ mm TARGET_PRODUCT=beagleboard

This sould generate a android vnc server executable (androidvncserver) which will be used to run on board.

Thanks Pankaj for your reply.

i have following doubts :

1. as you said for VNC server :

$ cd <android source path>/external

in this what is <android source path> ? which packages i have to download ?

2. I have downloaded compiled binary for vnc server from following link :

http://code.google.com/p/android-vnc-server/downloads/list

but when i run this on the beagleboard it gives following error :

Initializing framebuffer device /dev/graphics/fb0...
xres=640, yres=480, xresv=640, yresv=2880, xoffs=0, yoffs=1920, bpp=32
Initializing keyboard device /dev/input/event3 ...
cannot open kbd device /dev/input/event3

3. I want to use ethernet over usb then i have to use USB mini-B cable. If i use mini-B cable then will it supply power to the board or i need to use external power supply ?

In which application we need USB mini-A cable ?

4. This is not related to VNC server. I want to use Beagleboard as video streaming server. will you please provide some info about this ?

thanks in advance...

regards,

sachin kharude.

Hi Sachin,

Ref #1. Android source path is a path which points to android source directory.

You should download and compile Android sources before building Android VNC server.

Please refer to below wiki for more details about getting and compiling source code.

Ref #2.

Connect keyboard and mouse to your board and try running your VNC server binary.

Hi,

Please try with attached Android vnc server binary.

Rename androidvncserver.txt to androidvncserver, set executable permission and try.

8233.androidvncserver.txt

Hi,

Thank you very much pankaj the androidvnceserver you provided is working. but the problem is on the screen it is only showing green android robot and it hangs there.

for this problem i followed your solution on the following link : http://groups.google.com/group/rowboat/browse_thread/thread/5bb21fec8ec19743/ea10d03c16eac453?pli=1

to change the bootargs I used setenv and saveenv command in uboot but it is not working. then i realised that i have to edit boot.scr file. then using nano command in terminal i did edit boot.scr. then i copied that boot.scr to memory card then tried to boot Beagleboardxm but it's not working.

i got following error on terminal

after this i used bootd it gives following error

then i used bootm command it gives following error

thanks again for your help...

Editing boot.scr will not work. You need to use the mkbootscr utility to generate the new boot.scr.

This is available in the DevKit Download page in the Tools package. Do refer to the README file for instructions.
