WNDR3700v2 + OpenWRT Backfire 10.03.1-rc5

[Dick]

Hi,

I'm trying to install a MediaTV Pro on a Netgear WNDR3700v2 running OpenWRT Backfire 10.03.1-rc5.
There seems to be a kernel mismatch with usbkhelper.ko:
usbkhelper: version magic '2.6.32.16 mod_unload MIPS32_R2 32BIT ' should be '2.6.32.27 mod_unload MIPS32_R2 32BIT '

Is it possible to get a newer usbkhelper for kernel 2.6.32.27?

Thanks in advance!
Dick

This module is not needed anymore. Did you try to use the driver without it?

[Dick]

Ah, OK.

I'm trying to get tvheadend to work but the MediaTV adapter doesn't show up on the list, so I started the search with the obvious ;-)

I'll continue my search, thanks for the clarification.

/edit
btw: mediaclient --lsusb gives no result either. Could that be a problem?
mediacleint -e shows the full stuff.

[Sundtek]

try one of the following things:

if libmediaclient.so is in /opt/lib

export LD_PRELOAD=/opt/lib/libmediaclient.so

if libmedaiclient.so is in /tmp/opt/lib

export LD_PRELOAD=/opt/lib/libmediaclient.so

afterwards restart tvheadend and it should detect the adapter.

For the broadcom MIPS please change the transfermode to Bulk in order to lower the system resource requirements.

/opt/bin/mediaclient --dtvtransfermode=bulk or /tmp/opt/bin/mediaclient --dtvtransfermode=bulk (and replug the device)

try one of the following things:

if libmediaclient.so is in /opt/lib

export LD_PRELOAD=/opt/lib/libmediaclient.so

if libmedaiclient.so is in /tmp/opt/lib

export LD_PRELOAD=/opt/lib/libmediaclient.so

afterwards restart tvheadend and it should detect the adapter.

You're the King!

Thanks, it works now.

And ... I screwed up

After uploading a fresh firmware, I can't get tvheadend tot work anymore.
When it starts, it says

Code: [Auswählen]

[ALERT]:dvb: Unable to open /dev/dvb/adapter0/frontend0 -- No such device or address
[ALERT]:v4l: Unable to open /dev/video0 -- No such device or address

AFAIK, the adapter is loaded correctly but tvheadend does not connect:

start_sundtek() {
        export LD_PRELOAD=/opt/lib/libmediaclient.so
        [ -e /opt/bin/mediasrv ] && {
                /opt/bin/mediasrv -d > /dev/null 2> /dev/null
                /opt/bin/mediaclient --start > /dev/null 2> /dev/null
                /opt/bin/mediaclient --enablenetwork=on > /dev/null 2> /dev/null
                /opt/bin/mediaclient --pidfilter=on > /dev/null 2> /dev/null
                /opt/bin/mediaclient --loglevel=off > /dev/null 2> /dev/null
        }
}

Any ideas on how to proceed?
Is there a kernel module that has to be loaded?
I'm pulling hairs ...

You need to export the PATHS again:

export LD_PRELOAD=/opt/lib/libmediaclient.so
