    Raspberry pi sd card issues

    leasideflames30

      Even when everything is connected, my rasberry pi won't boot up. The pc (macbook pro) I am using as a display just stays on its normal screen. I suspect that this problem has something to do with my NOOBS-installed, formatted sd card, which will not load onto the pc even inserted properly into the sd slot, so I had to use a card reader to set it up. For some reason the sd card works only with the reader. Do you guys have any advice on what is causing this problem, and if so, what I can do about it?

          You have an HDMI cable that connects the Raspberry pi and the Macbook?

           

          This is a "problem" with the HDMI cables: They fit both ways around. This means that when you're connecting your raspberry pi to a TV you can plug the cable into your TV with either end and fit the other end in the raspberry pi. You never have to turn the cable around like with mains plugs or USB cables that have different ends.

           

          But it also means that you can fit the cable from one TV (image-showing-device) to another TV. Nothing will happen. And you can fit the cable between two image-producing-devices, for example a raspberry pi and a macbook.

           

          Your macbook cannot display an incoming HDMI signal on its internal display. You need a TV or monitor with an HDMI input.

            I have an HDMI to mini displayport adapter that I am using to connect the pi to the HDMI cables to the mac. All of the cables work fine, as I have used them to connect my mac to my tv.

              If you are using a straight male HDMI to male HDMI from your Raspberry Pi to your TV it should work.  This should at least show your Pi is working.

               

              I'd be cautious of using an HDMI to VGA or HDMI to DVI converter when you connect your Pi to a PC monitor.  In this case you really need to purchase an 'active' adapter that has power connected to the converter.  The economical HDMI converters are not 'active' and can draw more current from the Pi HDMI interface then the specification allows.  Doing this can cause your HDMI out interface to burn out in the Pi.  Always look for an 'active' converter that is self powered and then you can use any PC monitor for your Pi.

               

              I purchased a self powered active HDMI to VGA converter and connected my Pi to my PC monitor  This works great!  I find this an easier approach as a TV for a monitor just doesn't work well for me when you're dealing with such tiny fonts.

                I will try to connect my pi to my tv, though.

                  Hi Liam

                  this sounds like something I ran into with an XBMC SD card. I would try a couple of things:

                  First take a look at the symptoms of the boot failure (ie any lights flashing, screen displayed, etc??) and compare that to this debug page
                  R-Pi Troubleshooting - eLinux.org 

                  Or, create another, new NOOBs SD card and try to use that one....this is what worked for me

                  Good Luck, let us know how it goes

                      What I thought was an sd card is actually a micro-sd adapter, but it is specifically made for the pi, and I ordered it from element 14 / newark so it should be compatible with the pi. It is also brand new. When I plug it into the pi the green led on the pi glows softly, but not very brightly. Thanks for all of the help so far!

                          HI Liam your response seems to remind me with an issue I had with my first PSP. It doesn't use isr SD cards but I used an adapter that made a conversion to SD. I bought two of them I has two PSPs and ond worked fine the second didn't so prrhaps you could change the adapter too and make ot work. My point is your weak glow of the green LED seems like a contact issue that my problem too. But I guess uou tried this option by now. Anyway goodluck and keep us up to date with your progress.

                            The green LED glowing faintly means that RasPi hasn't executed any boot code yet: see the RasPi Troubleshooting Wiki.  The green LED will probably do the same thing without the Micro SD adapter plugged in.

                             

                            This is a silly question, but you do have a Micro SD card in the adapter, right?  If so, maybe the Micro SD card is bad or the image wasn't copied properly.  Check the Troubleshooting Wiki for most of the things that go wrong with RasPi.

                                John Beetem, it does do the same thing without the adapter. And yes, I do have the Micro SD in the adapter.

                                    There are quite a number things that can go wrong.  The most common is power supply problems, often due to a Micro USB cable with conductors that are too thin.  It's also possible that your SD card image wasn't written correctly.  If only the red LED is on and the green is only dim, it means that for whatever reason the RasPi boot ROM in the SoC isn't able to find a valid executable image on the SD card.

                                     

                                    Do try booting with no peripherals attached.  If the green LED flashes a bunch of times in the first 20 seconds or so, it means that the SD card is being read.  If this is the case, a peripheral is loading down the power supply: plug them in one by one to see which one prevents RasPi from operating.

                              Sometimes the issue is the SD Card using a newer faster model with sufficient free space does the trick. Try a virgin new card that has been fresly formatted and not have been used before as formatting normally leaves traces of previous projects. Good luck however...

                                I have plugged the pi into my tv and it still does not work. I have checked all of my cables and they work fine.
