Re: Disable 10ms interrupt on core 2&3
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...

Re: SSH server with two ports.
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...

SSH server with two ports.
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...

Re: /etc/rc.local won't save ??
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 ?

Nick

Re: /etc/rc.local won't save ??
... 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.

Re: /etc/rc.local won't save ??
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...

Re: Git problem.
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.

Re: Git problem.
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!

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...

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...

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 ...

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 !??!

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 !
