I have a raspberry pi B+. I installed raspbian OS on 16GB SD card and put it in to raspberry pi(work properly). Now I want to install opencv on it. But it shows only small available memory.(cannot install opencv on it, because of not enough free space).
how can I get more memory. Is there a special way to write raspbian image in SD card(like partition the SD card and install raspbian). looking for your help. thanx.....

Fresh raspian images are 2GB. If you copy such an image to a SD card, everything beyond that is unused. Fortunately this can easily be fixed.
In a console enter:
sudo raspi-config
The menu, which appears has as first menu item:
1 Expand Filesystem Ensures that all of the SD card
storage is available to the OS
1 Expand Filesystem Ensures that all of the SD card storage is available to the OS
Use it and you are done.

I have purchased a raspberry pi 3 b+ kit from Amazon. No complaints, but recently I decided I would update NOOBS from 2.7 to 3.0.
When I connect the SD Card to my PC (Debian Stretch), it shows as if there’s 3 separate SD Cards. Being case sensitive, they’re called SETTINGS, System and Storage.
Why does this sd card show up as 3 separate card on my PC?
What I have tried:
I deleted the contents of System, Storage and SETTINGS and replaced
it with the files from NOOBS 3.0
I google searched for why the sd card shows as 3
I put my phone’s sd card into my PC and it showed as 1 sd card (but
I’m not willing to switch cards)
If you already run Debian on your PC, I would probably recommend you ignore NOOBS altogether, and just flash the whole Raspbian image to your SD card.
Then touch boot/ssh to start sshd and add a wpa_supplicant file to boot partition so your WiFi can connect.
When you then start your RasPi, just run sudo raspi-config and expand your root partition and all will be good.
I am facing problem to flash android 6.1 or android 8.0 img file.
I follow orange pi user manual instruction but at last I download SMART PHONE FLASH TOOL and trying to flash .img file but when I click download button it stuck and nothing happen.
I also installed driver for win7 64 bit.
and also connect Laptop and Orange pi using USB Data Cable.
Please help me.
Orange Pi version - 4G IoT
SD Card - Class 10, A1, 16GB
tool - Smart Phone Flash tool as in user manual instruction
SD card is not necessary, you can flash it to board internal storage.
To get it working you need to press and hold power button for 1-2 seconds, after board was connected to PC
I have two OS's Raspbian and RetroPie. Both are store on two separate micro SD cards. I have a Retropie's SD card connected to a usb adapter. In the picture you can see that the file is right above the terminal window. Right now if I want to switch back and forth I have to take the Raspbian SD card out of my Raspberry Pi and put in the RetroPie's SD card. I'm wondering if there's a way that I can just boot it through Raspbian. Any ideas?
I don't think the Raspberry Pi supports booting from USB but if you had a large enough SD card you could dual boot from the same SD card using NOOBS.
You will find everything you need here : HOW TO BOOT FROM A USB MASS STORAGE DEVICE ON A RASPBERRY PI3
But you will always need an SD card at the beginning. I think some people booted pi1 and 2 with usb by putting special boot files into the SD card. Needless to say, it will be easier with a pi3 !
I have a waveshare 3.5 inch touch LCD display and I m trying to get it working with the latest version of Raspbian A.K.A Raspbian Jessie. I followed futurice.com 's tutorial on getting it to work (tutorial is titled I'd like some LCD on my pi) and it worked on Raspbian Wheezy just fine. All I get now is a blank white screen. All help is greatly appreciated! (I must use the official Raspbian Jessie image without NOOBS from the Raspberry pi website.) I have a Raspberry Pi 2 Mobel B +.
From the product page:
Why the LCD doesn't work with my Raspbian? To use the LCD with the
Raspberry Pi official image, driver should be installed first. Please
refer to the user manual. However, for the first testing, you may want
to use our provided image directly. Why the LCD still doesn't work
with the Waveshare provided image? Make sure the hardware connection
is correct and connects fine. Make sure the image in TF card is burnt
correctly. The PWR will keep on and the ACT will keep blinking when
the Raspberry Pi starts up successfully, in case both of the two LEDs
keep on, it is possible that the image was burnt incorrectly OR the TF
card was in bad contact. Which power supply should I use? It is
strongly recommended to use a stand-alone 5V/2A power adapter, because
the PC's USB port might doesn't have enough power to support the Pi
and LCD. For more info, please check the wiki page
You can find more info on their wiki.
It sounds like you either need to use their Raspian image, or install the driver for this display on your existing Raspian install:
wget http://www.waveshare.net/w/upload/7/73/LCD-show.tar.gz
tar xvf LCD-show.tar.gz
cd LCD-show/
sudo ./LCD35-show
I downloaded the necessary files for Raspberry Pi onto a MicroSD card, although the MicroSD card is no longer readable. When I put the card into the computer through a MicroSD to USB adapter nothing shows up in Windows Explorer. The card isn't present in Windows Disk Management either.
How do I fix the MicroSD card to get Raspberry Pi running properly?
If the Pi won't boot off it (ie can't read it) and Windows can't read it I would assume the card has died, is it a good brand or a no name one? It may be worth just grabbing another one to test with.
