Why Raspberry Pi 2 is not booting? - raspberry-pi2

I have flashed Tizen image into sd card and trying to boot Raspberry pi 2. But it is not booting.
SD card Info : Samsung 16GB Class-10 microSD card.
I have downloaded image from http://files.s-osg.org/tizen-on-rpi2/
and flashed
tizen-common-core-image-crosswalk-dev-raspberrypi2-20150811204400.rootfs.rpi-sdimg
and
tizen-common-core-image-crosswalk-dev-raspberrypi2.rpi-sdimg-2015-08-14
None of them are booting.
Is there any spec of SD card or anything am I missing?
Please help me.

There were two separate problems:
The SD card image was corrupted; the green ACT light had not been blinking. I re-formatted the SD card using SDFormatter and flashed it again.
The HDMI to VGA cable had been faulty. I replaced it with an HDMI to VGA converter.
After addressing the above problems, it began working just fine.

NVIDIA Shield - USB to HDMI

SHORT QUESTION:
Will a usb(male) to hdmi(female) adaptor work with NVIDIA Sheild?
Full Question:
I am trying to connect my surround sound hifi with my nvidia shield separately to my TV. Would a usb to hdmi work on the nvidia shield to pass the audio through. Any issues with drivers?
End Goal:
To connect 4k to TV and separate 5.1 audio to hifi box
Currently Tried:
HDMI splitter - it only chooses the lowest audio output which is the TV (2.0) not the required 5.1
Notes:
Hifi box supports hdmi passthrough but only at 1080p

ToupTek XCAM4K8MPA camera connection to Linux computer

I'm trying to connect a ToupTek XCAM4K8MPA camera to a Linux Ubuntu 20.04 64-bit computer to use with their provided ToupLite software for microscopy image capturing. The camera comes with a USB 3.0 cable, HDMI cable and USB WLAN adapter.
I have managed to set up the ToupTek ToupLite software (Link to manual, Link to download page) which, as far as I understand, comes with the SDK included. I have then connected the camera via USB 3.0 and HDMI cable to the computer, but ToupLite shows No device as in, the camera is not recognized or connected. I have tested the camera by simply connecting it to a computer monitor via HDMI cable and it works, but for capture I would like it to be connected to a computer and the WLAN or Wi-Fi connection solution is not really a good option.
Perhaps someone has some ideas of what I am missing.
Note: Relevant tags include touptek, touplite, microscopy
I ended up using the WLAN connection. Made a non-changing IP address for the camera and the ToupLite software recognizes that it is on the local network.

raspberry pi 3 (raspbian on sd card ) doesn't boot using linux mint laptop

i tried both noobs and raspbian on sd card to try to boot the raspberry pi 3 but none of them seem to do the job (if the sd card is the problem )
when i power it up , there are 2 lights , red and green
there is a sign that the keyboard and mouse are working , but still
NO DISPLAY on the laptop screen !!!
p.S : i'm using an hdmi cable that used to be working with our tv .
Did you verify the install before attempting to boot? I did the same from my Linux Mint box and it did not format it properly the first time. You have to verify the install per the Raspberry OS install instructions before attempting to boot with it.
Once verified, make sure you insert the card while the power is disconnected from your Pi. Also make sure you have your HDMI, keyboard, and mouse plugged in BEFORE connecting the power the first time you boot. Also, if you plug the power in before the HDMI the Pi 3 will boot to a headless state, plugging in a monitor after this will not work. You will have to unplug the power and plug it back in with the HDMI left plugged in.

Probleme about rebooting the Raspberry PI after update and upgrade

As you can read in the title of the post, I have a problem about rebooting the Raspberry PI after doing :
sudo apt-get update && sudo apt-get upgrade.
When the updating and upgrading finished, I restart the Raspberry and I just have a black monitor and the POWER LED (Red) is ON and the Green Led is also ON.
This is the second time the problem appear on my Raspberry PI.
Today, I downloaded the Raspbian and did all the manipulation to boot the Raspberry. And now the problem re-appear. The First time that the problem appear, I just formated the SD Card and I wrote the Raspbian in the SD Card.
If some one had the same problem, please help me to solve it.
Thank you in advance.
PS : I am using a Raspberry PI model B+.
I had similar problem like You.
For me, I have 2 possible reasons :
1) Power Supply - I recommended 5V 2A Power Supply
2) Network ethernet patch cable unshielded (without shield or ground line)
This problems with cable I had also on R-Pi2. Buying shielded cable solve my problems with R-Pi hangs on boot after reboot.
Now my cable looks like this one :

The problem resides in the SD card. When the green LED isn't blinking, it means the Pi can't read the SD card. To fix this, get a new SD card.

Using Arduino to connect Android tablet to USB Accessory

I have an Arduino-compatible board with USB Host Shield. It is connected to an Acer A100 Android tablet running "Ice Cream Sandwich" (Android 4.0.3) with Kernel 2.6.39.4. (The tablet has a USB micro connector and does not support USB HOST mode and therefore cannot connect directly to a USB accessory device.)
This picture shows what I have been able to do successfully (but with my tablet in place of the phone).
http://www.seeedstudio.com/wiki/File:SeeeduinoADK_Setup.jpg
I would like to find an example of using an Android tablet connected to a USB Accessory (such as a keyboard or flash drive) via Arduino.
Connecting the USB accessory to the Arduino's USB micro connector (using an external power supply) does not work.
Can anyone provide me with such an example?
Theoretically it should work, I haven't tried it yet though.
Arduino should act as the middle man and should relay signals both from your tablet and the accessory.
What code are you use?
This is: adk_release_20120606?
And what board are you use SeeeduinoADK?
I use board Seeeduino ADK, but unfortunately I could not make it work in USB accessory mode. My board work in only ADB (MicroBridge mode). See my work example
My tablet is Ainol Aurora with Android version 4.0.4 (CyanogenMod 9)
