restart work with RPI, check on new installation way: a 1.2GB live install system.

after a long break to document some knowhow to online calc tools,
google drive spreadsheets
and travel to see family,
now i was thinking where to start again.

checking on the newest version of RPI system found NOOBS and read also revision of quick-start-guide-v2_1.pdf
this looks easy and can choose/select ( even later ) between 4 operating system options,
but don't get confused, its not a multi boot , only a multi (re) install framework.
and its so big because the 4 linux are provided already.


berryboot also a stand alone installation tool, with some differences:
- installation same way like NOOBS:
unzip the distribution to a FAT(32) 4.. 32 GB SD card.
- the selected ( newest ) linux versions for RPI must be downloaded at selection
- it will create a MULTI BOOT
- it can install on USB ( stick and drive )

For advanced users:
Headless installation (install Berryboot without display attached, using VNC)
tia, that did not work for me, error connection refused.
more help for berryboot

sooooo, for the test i now wait until i have my HDMI port monitor/TV
TATA, here it is, a 23" THOSHIBA TV 23PB200T
with VGA and HDMI, fullHD resolution ... ( for 153euro )
add you see
- the wireless keyboard mouse logitech
- the belkin powered USB hub
- the powerline ethernet adapter for internet connection ( up to 300m ) in the whole house on the 240VAC house installation.

but as i not play long time RPI i forget how to use:
first test with SD card from my first setup,
start with: login pi pw raspberry, startx
stop with: logout and sudo halt at terminal.

somehow it not uses the full screen ( like the with HDMI connected laptop )
and the resolution is on 1824*984 and only other option is AUTO???

but the job is to play with the new installations:
** download and install PUPPY_alpha_4
( get Squeezed Arm Puppy V 5.105 )
in quick setup change to audio settings: output to HDMI
ALSA sound, test sound not work on (HDMI) TV, but WUFF WUFF ok on stereo analog out.
chromium browser works, but no thai character shown.
after reboot ethernet connection don't work

copy the content of the 1.1GB zip file to the cleaned SD card, boot RPI
and get
ERROR SD card has now been formatted ready for NOOBS installation, please recopy the NOOBS files onto the card and reboot

very strange, was it only a bad day??
tried format, copy... again, no use, no idea whats my local problem?

now if you read usable SD cards you will see that there are many card what are not working with ALL systems.

i play with the Win32DiskImager.exe and burn and backup the card.
and because its slow i can not recommend to buy big cards at first
( 4GB would have saved me a lot of time at backup )
A backup image file is always same size as the card (8GB) but as ZIP only 1GB,
and i would not know how to bring it on a 4GB card??

and also i not see the class (4) to class (10) difference in system speed?
here i used a
Apacer 8GB class (10) microSDHC with adapter (AP8GMCSH10-R) from BIG-C 249THB,
what is listed as GOOD in 7/2012.
now the
Kingston micro SD HC 8GB class(4) (SDC4/8GB) what is listed as GOOD and BAD.
but get same error msg at boot??

after some browsing try to format the card with the SDFormatter (4.0)
and copy on the NOOBS files again.
and test with it the PIDORA installation, the biggest pack there, installation with the pack on the
SD ( ok the class 4 one ) should have been fast, but not. Actually i expected there
a big advantage for NOOBS vs. BERRYBOOT where OS-system packs download is needed.

You needed user and password ( 2 times) config (i used "pi, raspberry, raspberry" )
midori browser can no thai char and can not resolve host name ( besides google..)
system has no application to offer for jpg,mp3,avi .
over all disappointing.

reinstall: NOOBS + debian
and try a media player in here: VLC (
start LXTerminal admin
sudo apt-get update
sudo apt-get install vlc
pls find system other AND system Sound and Video : VLC media player
GRRR i still don't know how to make link / icon on desktop, poor linux knowhow.
1. music: play mp3 file
2. picture, jpg files select ALL FILE , see picture in dir. open, play it for 10 sec.
3. video avi and mpg: vlc not play, cpu 100%, can not quit vlc, must reboot by power off

but here a other short test, the debian midori browser ( compared to the other linux..browsers
works here without the can not resolve host name error ) on a heavy job:
cpu on 100%, very slow BUT IT WORKS.
so, WHO NEEDS A 500$ computer with a 800$ MS OFFICE when a 35$ computer, TV and internet access can do same? 555 ( 555 in thai language is pronounced hahaha, so used as LOL )
also google+ ( what calls the old google talk now HANGOUT )
chat works nice, and i want to get rid of skype / microsoft anyhow.

- want also test Raspberry Pi media center distribution, created by Sam Nazarko
install from raspbmc windows installer
the test of the online installation show startproblem, it not find online update link.

and i start digging about how to remove that partition thing and get my 8GB FAT32 again.
can not do by windows?
already think about to buy a new SD card, but i see that in the installer
of the raspbmc
is the [Restore device for formatting] button.
and then windows (computer / disk management) can format the 8GB card again
! wait ! better use SDFormatter.
under the Format OPTION: Format Size Adjustment ON
you get back your full SD card.

play also with the RASPLEX , a mediaplayer only,
again the installer made many problems, only the stand alone image i could use.
mouse AND TV remote not work, only keyboard arrow key and enter work.
but as it also found not even the USB stick with a movie, i could test, PLAY nothing.

ok, back, clean SD, and again use
at first download the default RPI : Debian Wheezy Raspbian

second: download OPEN ELEC 3.0.3 ( XMBC V12.02 FRODO ) mediaplayer.
now that is much better! from usb stick can play mp3 music, jpg picture and avi video,
for mpg video hear the sound, no video ( need to buy codec? )
the screen adjust is tricky but possible.
and with the weather a internet application is working.
what so strange on my concept: to make a old style TV
to a modern smart TV ( with usb player and internet access ).

now, in the combination with the boot menu of berry boot
that short comings of a media player are more acceptable.
but actually i would like a multimedia linux with that player as application more.
( add a android style skin for it would be nice )
keep searching... possibly i can also find a stand alone web browser OS for RPI?

some good info

and about required license keys
with cat /proc/cpuinfo find that required serial number.
as i have ordered mpeg-2 and vc-1 codec, now need to learn how to install it.

more info , also here

got the mail after one day.

even i tested that i can reach both systems by putty SSH,
( debian: pi raspberry and openelec xbmc: root openelec )
first i try just to edit the config.txt file in the fat partition of berryboot.
it worked, i tested a spec. file on openelec xbmc.

But with the NOOBS it is different,
there you can reach only the RECOVERY partition,
and making a new config.txt there is of no use.
you have to run your OS ( here i just have the debian installed ) and go /boot
and edit the existing config.txt by adding the codec lines at the end.
its a long file with many options, but none is enabled.

now it works on both SD cards.
but i had the VLC player installed and that still makes problems ( not play mpg and can not be stooped) !!

more about the players:
on debian there is a good commandline player installed,
now, instead of using a command / terminal window , cd to the movie files and call
omxplayer mymovie.mpg
you can from desktop start the filemanager, rightclick on a movie ( context menu ),
open with ... commandline omxplayer f% click for all.

but the HMI for that player is keyboard, see keylist well, and looks like even that does not work.
but there is a other trick where it works with the keys:
get a different terminal if you like:
sudo apt-get install xterm
in filemanager right click one of your movie files and
select open with, then click custom command line tool, type in:

xterm -fullscreen -fg black -bg black -e omxplayer -o hdmi -r %f

and check the box saying always do this,
so you only have to double click on any file of that type in the future and it will do the same thing.
repeat for other types too.

as ( see link above) recommends
i try some tuning in config.txt

and test the results.

vcgencmd measure_temp
vcgencmd measure_volts

for src in arm core h264 isp v3d uart pwm emmc pixel vec hdmi dpi ; do echo -e "$src:\t$(vcgencmd measure_clock $src)" ; done



it has some side effects, like the xbmc HDMI screen adjust changes with that??

NOTE: there is warning that core freq. tuning of RPI makes problems to class (6), (10) SD cards!
