Help needed with a busybox ...

Sat Sep 12 15:47:50 UTC 2009

Hi folks,

I realy apprechiated (?) your work and would be very thankfull if you could
help!

I did get this lcd tv as a pre-series-model on a fair for a good price. But
(here comes the but!) it is configured as an IP-TV System. The guys at the
booth told me that it would support also a standard STB (Set Top Box)
feature. It has all the neccesary connectors like ZF, S-VHS, RCA ... and
RJ45.

I am working in IT as a windows sysadmin and I have limited knowledge of
Linux. I have also a good knowledge on computer hardware and electonics.

So I started my PuTTY and were able to connect as root. In a readme file in
the system root it says "IPTV - standard IPTV configuration. STB - standard
STB configuration".
I also did manage to find out that in "/etc/init.d/" are 5 files: rcS*,
S01sysinit*, S20urandom*, S40network*, S50auto*
the rcs seems to just call the other files in ther numerical order. S01 -
S40 seem to be standard configuration. In S50auto it says:

mkdir -p /product

modprobe jffs2
mount -t jffs2 /dev/mtdblock6 /product

sh /product/auto.sh

and in this called auto.sh it says

#!/bin/sh

# --- CONFIG VALUE -----------
IP_SVR=192.168.2.150
IP_STB=192.168.2.201
IP_GW=192.168.2.1
IP_DNS1=168.126.63.1
IP_DNS2=202.30.50.50
IP_PREPARE_SEC=0

echo "nameserver ${IP_DNS1}" > /etc/resolv.conf

#done

Now, in the /IPTV/etc folder are two files and one folder: directfbrc
init.d/     smp8634rc

uclibc[etc]$ more directfbrc
# A sample DirectFB config file
# For possible value for the parameters below, run any DirectFB app with
this command line:

#

dtv-signal=720p                                 # use none to disable the
output
dtv-connector=dvi
no-connector=hdmi

# Component output configuration (YCrCb, VGA)
component-tv-standard=hdtv60
component-signal=sdtv# use none to disable the output
component-connector=ycrcb

# Analog output configuration (Composite, S-Video)
analog-tv-standard=ntsc
analog-signal=ntsc                              # use none to disable the
output
analog-connector=cvbs

# A file with our implementation-specific configs
# The paths are relative to the board root !
driver-options=/etc/smp8634rc

# The size of the OSD and Background surfaces
mode=1366x768

#Uncomment this for detailed configuration messages
#show-cfg-info

# Tweak these 2 values for different adaptive deinterlacing behavior
#d2_proportion=0x7682
#motion_config=0xffffffff

# Specify the initial deinterlacing type
deint-type=bob

and

uclibc[etc]$ more smp8634rc
#Support out LVDS, disable HDMI output
dvi-hdmi-processing=0,connector-cmd=0x00000010,"-digital -dvi_hdmi lvds -bus
24 -asp 16 9 -vmf /LINK/ChiMei_V32B1L01_1366x768x60.vmf -f HDMI_"
uclibc[etc]$

in the /init.d is again the same S50auto* as mentioned before (is it the
same one, and the other is just a link to this one?)

in the /STB/etc

uclibc[STB]$ cd etc/
uclibc[etc]$ ls
directfbrc  smp8634rc

are only these two files (again?)

uclibc[etc]$ more directfbrc
# A sample DirectFB config file

#       <app> --dfb:help

#d2_proportion=0x7682

and

uclibc[etc]$ more smp8634rc
#support HDMI, YUV 1080i
connector-cmd=0x00000020,"-digital -dvi_hdmi siI9030 -hdmi2c 2 -f
HDMI_"#Envision board

....

So, what should I do? how do I change the config so that it will run as STP
and not IPTV anymore? It has recognized my USB Stick. Can I put the complete
running system as backup on this stick to have something working again if I
screw up?

Cheers so much, I hope my english is not so worse as my linux knowledge ...
