Re: Camera module freezes RPi (reproducable)

Are you accessing it over wifi? If so, which chipset is it based on? I know of some people who have seen issues with Ralink-based ones making the Pi freeze up (myself included).

Re: Camera freezes

Sorry no, I hadn't played with the sunny cable. Just both ends of the main cable. At a glance the sunny one looks fine, would it be obvious if disconnected (ie. Just hanging)? I saw your message that you already tried reconnecting it, but just replying to this to answer your question. With mine, th...

Re: TimeLapse causing Network drop

I've looked around and found posts from others who have also had similar issues with Ralink-based devices on the Raspberry Pi, though it seems that using it in combination with the camera may make it happen sooner, as they were talking about it freezing after hours to a day or two of usage (this was...

Re: TimeLapse causing Network drop

I bought an EDIMAX EW-7811Un which uses some type of Realtek chipset rather than Ralink and it seems to be working fine. I streamed video for over an hour with no issues. At some point the video stream stopped and I thought it froze, but then I looked over and realized that my battery pack ran out -...

Re: Using dd to backup a PI SD

Maybe it depends on the distribution or which shell you are using. I've had mine be picky about where I place the sudo, so I always put it on the command that specifically needs it.

Re: Using dd to backup a PI SD

In your restore example, I think you need sudo on the dd command rather than gzip, so your example should look like this:

Code: Select all

gzip -dc /home/your_username/image.gz | sudo dd bs=4M of=/dev/sdb

Re: WiFi with AES

I think the RSN means WPA2 and I think CCMP is a type of AES.

Re: How to verify a shasum

Technically it is not a visual compare the way I suggested, and unless you download the SHA-1 in a file, you are still copying and pasting something anyway. If you aren't doing a batch compare of SHA-1 hashes using such a file, the method I suggested is still a quick and effective way to do it. Anyw...

Re: How to verify a shasum

Usually I just use shasum and copy the SHA-1 from the output on the terminal, then open up the web browser's find command on the page with the SHA-1 and paste in the one that was calculated. It will only find an exact match, so if it finds it then the one you pasted matches the SHA-1 that the find c...

It is a name for the system, which can contain letters, numbers, and hyphens (though hyphens shouldn't be at the beginning or end).

Re: TimeLapse causing Network drop

I tested it again, but this time with the HDMI hooked up to a monitor and the wifi dongle plugged into a powered USB hub instead of directly attached. Based on bit-rate and the size of the video file recorded, it probably froze after about 30 minutes. It is being sent over the wifi with netcat to an...

Re: TimeLapse causing Network drop

I've been seeing the same thing happen on mine; though I'm using a model A, so there's no wired network connection. I'm running it headless with wifi. Also, this was with raspivid rather than raspistill. I'm using a 2.1A USB power supply (a rechargeable USB battery pack, actually) and I haven't test...

Re: New features for raspistill command

Yes, disable_camera_led was already fixed to work again sometime sort of recently. There was an update that broke that feature not long after I got my camera (which I received two days after they were officially available for purchase), but the fix has already been in the updates available with apt-...

Re: Getting The Camera To Stream

Personally, I prefer to make the Pi the netcat server and the PC the client so I don't have to deal with the firewall on the PC at all. Based on those sample commands: On the Pi: raspivid -t 999999 -o - | nc -l -p 5001 On the Windows PC: [Path to nc.exe]\nc.exe [IP address of the Pi] 5001 | [Path to...

Re: ssh-netcat(nc)-mplayer

If that's all you want, you don't need to use any special parameters. Just do this: ssh pi@RASPI.IP.ADDR "raspivid -fps 10 -w 640 -h 360 -vf -hf -t 999999 -o -" | mplayer -fps 11 -cache 1024 - On the raspivid command you may need to add the parameter for adjusting the bitrate to use something suitab...

Re: New features for raspistill command

One potential use for that patch that was merged in to optionally execute a command for each picture taken would be to run a command to move completed files, so that a script checking for files does not see partially written files.

Re: file size limit on raspivid ?

If you send the output to stdout and redirect that to a file, does that work around the issue? For example, instead of:

raspivid -v -t 3600000 -o /media/usbdisk/vid/video.h264

Try this:

raspivid -v -t 3600000 -o - > /media/usbdisk/vid/video.h264

Re: Issue with getting camera to work

Mine had the exact symptoms that cmarty's had and the fix was the same. I had tried just pushing on it before but a couple days ago got it working when I unplugged and then reconnected that connection on the camera board.
