I presume you didn't get a satisfactory answer to your question . I got somewhat disillusioned and disappointed with the pi. It's not really intended for such real time uses. I went back to arduinos for that sort of stuff. I think the deficiencies in real time control of gpio is a significant drawba...

Unfortunately, it doesn't seem to be possible for my router to do what you have suggested :( It appears that the port number cannot be mapped. So, I can set up a port forwarding rule like this: <External IP Address, port 40000> -> <Internal IP address, port 40000>. You see, if I specify port 40000 t...

I know this isn't a raspberry pi issue specifically - but I'm sure you guys will know about this sort of thing. My Pi has a ZD1211 USB wifi adaptor. It also has the eth0 ethernet port (obviously). Sometimes I run the Pi with the ethernet plugged in, and sometimes just with the wifi adaptor. But, not...

Must be the SD card.
I've just got a new one, and it's working fine.

Problem solved then.

But, that Samsung SD card wasn't all that old - maybe 8 months.
And wasn't in continual use.
How long should these SD cards live for ?

... but, maybe not.

I've just tried to edit files with only the USB keyboard plugged in - no webcam, and no wifi.
And, the SD card is still not saving the data.

So, perhaps I do need a new SD card after all.

Ah, I think I know what the problem is ! My Raspberry Pi has a USB Logitech Webcam inserted. This Pi is used with a webcam and a motion sensor to upload instant webcam images to a server. It's part of the home security system. But, when I unplug the USB webcam I can edit the files OK, and the change...

I'm using Raspbian, kernel 3.10.25+ from Jan 3 2014.

Huh, even more weird!

I just created a new directory under /home/pi and added some new bash scripts and stuff.
And, when I rebooted - they had gone too !!!!

Is my SD card going bad ?

Hi, This seems to be a new problem to me, I don't have this with my other 2 Raspberry Pi's. When I edit /etc/rc.local (as sudo, using vi), I can make changes OK, and save them OK. And, after saving I can 'cat' the file to see that it's just as I editted it. Then, I do 'sync' a couple of times to flu...

I'm not sure if this is a proper fix for my problem.
But, I found a .gitconfig file, and a .git directory in my home directory.

I've renamed those.

Now, my SVN build tree is building as expected.

Thanks anyway.

Hi,

That 'find' command finds loads of stuff, both files and directories called 'config'.
Much of it is totally unrelated to git or svn.

Are you sure moving or deleting those files and directories will fix my problems?

It looks to me like it would break lots of other stuff!

"git rm ../../../../../README.md" results in : fatal: pathspec 'README.md' did not match any files. git status --porcelain shows stuff like: R README.md -> SVN/Proj/fs/skel/bin/.empty A "SVN/Proj/drivers/net readme .txt.svn-base" ?? .codeblocks ?? .config There are about 40 lines...

I know this isn't really a RPi question, but I've had a lot of help here, so I though I would try here first. I have a problem with 'git'. When I do 'git status' from the top directory of some source code tree, it tells me that a file called README.md has been deleted. It shows it like this: # delet...

Hi,
I run omxplayer like this:

omxplayer --live -o hdmi -r /dev/dvb/adapter0/dvr0

The --live option doesn't appear to do anything though.

Regards

Nick

nickon314

I know this is an old thread, but I see the same behaviour as you using the same type of DVB-T USB adapter.

Did you ever get a fix for this sorted out?

Regards

Nick

nickon314

I have a DVB-T USB stick plugged in to the RPi itself. Tuning is done using tzap. The red light on the DVB-T stick comes on almost immediately after running that tzap command - so I know the stick is tuned OK. tzap needs to keep running, so I either run it as a background '&' task - or login thr...

Hi, Back again with the same question. I didn't get much help last time. Essentially, my problem is that omxplayer takes over 20 seconds to start. I'm using a DVB-T USB stick. Once the omxplayer decides to start I do get audio and video out OK though. I start omplayer with the --live option, and I'v...

nickon314

OK, That's looking very interesting. I've now got my RPi to use WOL to wake up one PC. But, I have another PC which refuses to behave. I checked the BIOS, and enabled the relevant setting, but that one still doesn't WOL. I might have to use the GPIO pin/switch method for that one after all. Another ...

nickon314

Damn, Wake-On-Lan. Why didn't I think of that.
I feel such an idiot.

I suppose it's possible for the RPi to send such a WOL message ?

Hi, My Desktop PC has a push button on the front to turn the thing on. Pressing the button momentarily is all that's needed. And, inside the PC case, I can get to those two wires which lead to the push button, and momentarily short them out to do the same thing. Now, I've soldered some flying leads ...

So, you are saying that omxplayer loads and shows video in 4 or 5 seconds.

I wonder why 500MB RPi unit takes 20+ seconds to start omxplayer !??!

Nick

nickon314

OK, I've got the latest raspbian wheezy release. omxplayer is dated 16 Dec 2013. So, fairly new I guess. It does have the --live option. But, using it doesn't seem to make any difference to it's startup speed. omxplayer still takes 20+ seconds show video. And, I can't change channel simply by changi...

Hi,
Are you sure about the --live option?
omxplayer responds with 'Unknown option".
I just checked the source code on Git, and it's not one of the options !

I'm using the newest raspbian wheezy on my 500MB RPi. This is the release from 7th January 2014. I've had a lot of trouble in the past getting a DVB-T USB stick and omxplayer to work. But, this new distro has now got it working. I saw on a much older forum post that I should be able to do this: ----...

Sorry to re-awake this old thread. But, I've just updated my SD card to the latest Raspbian Wheezy (7th Jan 2014). I see the same problem as the OP when trying to launch the PiStore form the icon. But, if I open an LXterm, and do: sudo pistore then it loads OK ! Looks like the permissions problem st...
