So I recently purchased a Raspberry Pi 3 B+ and installed the Raspbian stretch with desktop onto my SD card. The first time I booted it up, it worked great! I was having trouble installing some python libraries. I decided to start again from scratch, and reformat the SD card and put a fresh OS on it. I'm using the official SD card formatter, and did a full overwrite on the card. I rewrote the OS image to the card, but now am stuck with a solid red light on start up. No ACT light at all, no image on the screen. I swapped it with a new SD card, and downloaded the Raspbian zip file again. Still nothing. I tried using the Raspbian stretch lite, still nothing.
Has anyone run into this problem? Any suggestions? Thanks!

I am trying to connect Kinect 360 with Windows.
What I try:
I try to connect it with Windows 10 (64-bit) and Windows 8.1 (64-bit) (both ware host OS).
I downloaded and Installed the Software Development Kit (SDK).
I downloaded and installed the Kinect for Windows SDK v1.8.
I downloaded and installed the Kinect for Windows Developer Toolkit v1.8.
Then, I plug the Kinect 360 in the electric power and connect it with my Lap Top using the USB 3. I am using a power supply adapter cable for Xbox 360 Kinect Sensor (see the picture below).
As a result, no new hardware ware listed in the Device Manager like no new microphone, no new camera, no new unknown devices.
BTW I am not sure if the Kinect hardware is working at all. I don't know how to check it - there aren't any lighting lights on it. I did some research, but I didn't see any lights on working Kinect 360 on youtube videos. So I don't know how to test whether the Kinect is working (without connecting it with XBOX).
I want to connect the Kinect sensor with the PC machine because I need to do some tests. If there are other solutions with another OS (like Linux-based or MAC OS), I can try it too.
there was the same problem, it shows up as a microphone, I thought the problem was in the kinect itself (I thought it was broken) so it lay on the shelf for 2 years. I updated my PC 4 months ago and it turned out that there is usb 3.0 on my old motherboard, but it is not supported (perhaps 3.2 is needed for it). Now kinect works fine and is being determined
I just started working with a Beagle Bone Blue and I have installed the necessary drivers however when I go to http://192.168.7.2/, it say the site cannot be reached because it took too long to respond. I would really appreciate it if someone would help be. Thanks!
I think the kernel image you are using in BeagleBone Blue must be properly booted in the board or if you are using eMMC0 for booting the board,
Check the kernel logs of booting using minicom in Linux or putty/Terraterm in Windows.
Also, check if there is one folder creating as BeagleBone(Getting Started) in Windows after proper booting done.
If you are using Linux, check the same type of folder and verify the internet connectivity.
Try to use new kernel image available from https://beagleboard.org/latest-images
Boot it using sd Card and flash it on the board.
Then, try 192.168.7.2 in the browser.
It will be working if you follow the proper steps.
I hope it helps.
I am having some issues with my RPi2. As I said in the title I have Raspbian installed. The system runs smoothly when I navigate files etc. But when I try to use the Internet Browser OR Navit (I am working on a project and I want to use the RPi as a navigator) then the system gets laggy and very very slow. I also notice that in the right top corner the cpu usage goes about 30% (sometimes more).
Raspbian is installed in a 16Gb Class 10 SD Card. I have expand the system via raspi-config and I have about 9 gigabytes of free space. I also have HDMI, keyboard and a wireless mouse connected.
Any ideas/suggestions?
Thanks in advance!
I downloaded the hard float image of Raspbian here:
http://www.raspberrypi.org/downloads
I copied the recommended hard-float image on an SD card and the Raspberry Pi boots fine with it.
Then I downloaded the soft-float version of Raspbian because I need it to get some software running that does not work on the hard-float version. I formatted the SD card again, copied the soft-float image onto it and tried to boot the Raspberry Pi with it.
Problem: the Raspbery Pi doesn't boot with the soft-float version of Raspbian!! I see the green "ACT" LED light up for less than a second. After that only the red power LED is on and nothing happens after that.
I repeated this process a couple of times and redownloaded the images, checked the SHA of the downloaded file, etc. It just doesn't work. The hard-float image always boots up (green "ACT" light flashes rapidly like normal).
Any ideas?
Update: If you have a newer Raspberry Pi with Hynix memory then the older versions of Raspbian will not boot. Specifically you'll need at least the 2013-02-09 Debian 7 (Wheezy) build.
See this post.
Now, the 2013-02-09 Wheezy build is a hard-float version, so you can't use that, but you can update the kernel image of your soft-float version which is actually independent of the Linux OS (I'm told that basically the GPU boots the Raspberry Pi, and it runs the ARM as a kind of co-processor). So, you can run rpi-update to update your kernel, and it should be all OK.
There's a bit of a catch-22 if you don't own any of the older Raspberry Pis that will boot the older images--how can you update the OS if the only Raspberry Pi you have is a newer one which won't boot? In your case it sounds like you have access to an older one, so you're OK. For those who don't, maybe someone will eventually post an updated soft-float version, but until then perhaps you can try the following. I haven't; it's just a theory, but at this point you don't have much to lose :-)
Burn the latest Wheezy image (2012-02-09) to an extra SD card
Mount this SD card on Windows
Copy all the files except *gz ones which correspond to the Linux filesystem. Basically, all the boot images and configuration files
Mount the SD card containing your soft-float image and overwrite the boot image files
Hopefully have a beer to celebrate?
Previous post:
Yes, I had this same problem. I don't know exactly what is wrong, but the start_elf image won't boot, at least with the recent set of Raspberry Pis. I can't believe Raspbian would release something that broken, so I suspect it works for some Raspberry Pis, but not others. What you need to do is:
Burn the hard-float copy of Wheezy to an SD card. You're going to snatch off the boot image (which works) and copy it to the soft float one.
Mount the SD card on a Windows machine. The boot partition is FAT, so you'll be able to see it. Look for the file start.elf. Copy it to your Windows machine.
Burn the soft-float copy of Wheezy to an SD card and mount it on the Windows box.
Replace it's start.elf with the copy from your hard-float one.
Crack open a beer and enjoy.
See my related post.
Just image one card with hard-float(Raspbian “wheezy”), and the other
with soft-float(Soft-float Debian “wheezy”). Plug both into a Windows PC and
copy all files (you can see at all) from the hard-float onto the
soft-float card, replacing existing ones.
Explanation: http://www.raspberrypi.org/archives/3534
P.S. You can, of course, copy those files to a temporary folder first,
swap cards and then replace all files on the soft-float card with
those in the temporary folder.
bootcode.bin
start.elf
fixup.dat
From Raspberry Pi SD card with this Soft-float Debian "wheezy" did not want to boot
When you dd the image, make sure bs=1M...
After trying all the things in the other answers, it was finally the way to make it work on a latest Raspberry Pi out of the box. I've actually found this a good help with several Raspberry Pi applications/code.
I'm working for an University of Applied Sciences and we want to buy some Kinects together with some PCs for future research as well as student projects and we are currently in a stage where we want to define which hardware to use.
We have a Kinect for Windows sensor and we are testing it with a Dell PC (Inspiron 15r 7520; Windows7 64bit, Intel i5-3210M #2.5GHz; 6GB RAM; USB 3.0).
We installed all the drivers for the 1.6 Version of the Kinect SDK but the PC only detects the Kinect camera once in a while.
In the device manger the "Kinect for windows Audio Array Control" and the "Kinect for Windows Security Control" show up but the "Kinect for Windows" Camera only shows up once in a while. If we plug and unplug the Kinect 10 (or 20 or 30 or 5) times the Camera is not detected 9 times. Then suddenly the camera is detected once and we are able to use it.
The next time we have to plug and unplug the camera 20 or 30 (or 2 or 5 or 10) times until the Camera is detected again. Then, we can plug and unplug the Camera 5 or 6 times and it is detected every single time.
Every time the camera is not detected a Windows USB Information (yellow triangle) pops up stating that a USB device was not detected.
We are quite sure that the Kinect sensor is not the problem because it works on 5 other PC without any problems. Then we thought about an USB Controller problem but after replacing the Mainboard and the USB Controller of the PC the error persists.
Are there any known PC - Kinect incompatibilities or can anybody think of a reason for this strange behavior?
Any help is greatly appreciated.
I'm not sure whether this includes recognising the camera, but there are known issues with certain USB host controllers and version 1.6. If you haven't already, take a look at this MSDN page under the "USB host controller compatibility" subheading.
It does mention two USB 3.0 controllers which are known to have issues. If you are using either the "Etron USB 3.0 Extensible Host Controller" or the "Renesas Electronics USB 3.0 Controller" you might have your answer.
