Need to reinstall OS every time after shutdown to boot

[kevin3372000]

I bought a raspberry pi 3 Model B recent days.

(My OS is the latest version of Raspbian)

And I met a problem : Every time I shutdown, I need to reinstall the OS into SD card to make it boot successfully.

I mean I can boot successfully after I install the OS into my SD card, but every time after I execute this command:

sudo shutdown -h now

to make it shutdown. It cannot boot successfully again.

I always do 'sudo shutdown -h now' and wait until only the red light is lighting. Only after only the red light is lighting, I will remove the power. So, it seems I didn't do any wrong when I shutdown it.

I have googled for two days, and I can't find any solution to this problem. I even tried the another SD card, but it has no help.

Can anyone help me? I really need someone's help. Thanks a lot.

Updated:

Just comment out this line in the config.txt:

Code: Select all

hdmi_force_hotplug=1

And it works!!

Sounds like you are using an SD card that reports a larger size than it actuallly is, and thus during use simply starts overwriting previously written data.
Such Often is the case with "fake" cards that are sold as 8GB cards while being actually just 4GB.

I have two cards. One is made by Transcend, and another one is made by Kinston. Both of this two cards are class10 16GB MicroSD cards.

Test them with h2testw to see if they're fakes.

I tested it using this software and it says "no error". So it means my SD card is not fake, right ?

Then you need to look at your power supply and the weedy bit of cable between it and your RPi.

Then you need to look at your power supply and the weedy bit of cable between it and your RPi.

My power supply is 5V/2A, but according to the official website's description, the recommended power supply is 5.1V/2.5A. Would this be the cause of the problem ?

I'm thinking if I need to buy the official one now. Could you give me some advice? Thanks a lot.

2 amps is more than enough to power a RPi3 if the only USB peripherals are a mouse and a bog-standard keyboard. But many supplies can't deliver the labelled volts and amps at the same time. That is usually not critical for charging the cells in phones etc but it does matter for RPis. And some USB to micro-USB cables have so much resistance such that the voltage actually delivered to the RPi is too low.

Does the red LED ever blink or go out? If yes, then your powering arrangement is certainly deficient.

I have checked that the red LED didn't blink. Do you think that buying the official power supply will solve my problem ?

Are you downloading a new image each time, or just reflashing the same image?

I tried both, but neither works. T_T

I changed my OS to Ubuntu Mate, and it works!!!

Do you have the same problem when using the latest version of RASPBIAN JESSIE LITE ?

[mahjongg]

Nobody else (that I know of) has this problem with either Raspbian or Raspbian Lite.

Perhaps you need to wait just a tiny bit longer after "just the red light", as after an intense session with many writes to the card (as happens during first run) it might be that the SD-Card itself needs to finish writing (flushing) data to the card from its internal RAM. That can last several seconds after Raspbian itself has shut down.
Its also possible the controller in the card has started some housekeeping tasks (swapping sectors to less used parts of the flash memory) that can last another several seconds.
Try counting to (at least) ten before turning off the power.

I waited for more that 1 minute, but it still not works. It's really weird.

I just used NOOBS to install Raspbian and it succeeded !!!

Do you know why this happened?

It does sound very odd. But, it's working now!

I follow this guide to install it without NOOBS:

https://www.raspberrypi.org/documentati ... /README.md

Is this guide has any problem ?

...are you using an internal or external SD Card Reader ???

I use Mac's SD Card Reader. So, I didn't use an external one.

Do you mean I need to use an external SD Card Reader ?

[fruitoftheloom]

Some Internal Card Readers IME have issues with SDHC SD Cards, therefore going to Poundland UK to buy a USB Card Reader may be prudent..

But it works when I install the Ubuntu Mate...... So maybe the SD Card Reader is not the problem ?

I really want to know if I'm doing any wrong T_T

You could still have a problem with Mate that you haven't hit yet...

I finally found the problem !!!!

I compare the config.txt generated by NOOBS and the config.txt installed with raw image. I found that the config.txt generated by NOOBS comments out this line:

Code: Select all

hdmi_force_hotplug=1

Just comment out this line and it works!!!!!!!!!!!!
