Yes, the kit came with a power supply.  Printed on it is the output voltage of 5V and 2100mA.  The red led stays on once the power is applied. So that should mean that the power supply should be okay?
It's a Pi2 but the starter kit is a B+

I'm running an image on my model 2 that is over two years old. But to get it to work you have to do apt-get update and apt-get upgrade to bring the software up to date. I have six of the new Pi model 2's running on this same image, I know it works.

Did the kit come with the latest NOOBS on the sd card?
If not or its a card from an earlier Pi then it wont work. You will need to down load and create an SD with the latest NOOBs on it.
I had the same problem as you describe when I took a known good SD from an existing pi and tried it in the 2.

Yes, it comes with Raspbian OS flashed on it.

I've been watching the video etc. but so far no luck. I did notice that in the video, all of the leds flicker away on bootup.  I will keep reading and thanks..

The red led came on steady and the green one to the left of it lit for a second or two then went out.
The monitor lit up indicating that it is 1080p and a Raspberry across the top and the background has the 4 standard colors in 4 equal parts of the screen but that's it.

I tried several times and got the same result each time.

I then took the micro SD card out and checked to see if there is any data on it and there is, just over 9 MB.  If there is supposed to be more than that how would I go about trying to view/read it to ensure that everything that is needed to get started is in fact on the card?  I'm wondering if I can't see it all because it may be bindery or something and not readily visible.  I'm using a windows machine to check the card.

Is there something else I could try to get it to boot up?

Re: New Pi won't boot up

A little more info is needed. Did you create the microSD card yourself or did it come loaded with your kit? I've read where some have received a card that wasn't loaded correctly. The card has two partitions on it, the first is formatted as FAT and the second is the Linux partition so windows can only read the first partition unless you install a utility that lets windows read Linux partitions. 

Did you happen to check the voltage of your power supply? There should be test points on the newer Pi's for checking that. On the Model 2 the red led will blink or turn off if the voltage drops too low. Can't remember if the B+ has this or not. The green led is a SD card active light and should flicker as the card is being read or written to.

If you have another memory card I would create it from scratch and see what happens. There is a good chance that will fix your problem. It's doubtful you have 2 bad pi's.

Mark Dymek <markdymek@...>
 

sounds like a power issue. did the kit you bought come with a 2.5amp power supply? if it did your supply might be bad. the fact that your getting minimal startup is not a software thing its hardware. before saying the pi itself is bad try a different supply. windows might not be able to read the filesystem of the card if its ext formatted. you “turned on the power switch” most supplies I’ve seen just have the micro usb plug that you connect to the pi. sounds like either you have a bad supply or you got some kind of weird thing. make sure your getting 2.5 amps.

Hi
   Your Windows machine will only see the boot partition which is small, the green light flashes shortly after power is connected then mostly flashes while booting.

Try using a different SD card or image, you can use Win32diskimager to flash a new image.

Hi Alan
The article at linuxtoys.org suggests that it is ASCII data.  I seem to remember that my Chinese made cheap DMM with RS-232 also responded as ASCII strings when I looked at it as a 1200bd serial port (under windows) with my USB to RS-232 adapter.  A quick check on the RPi2 also had results using a terminal emulator and /dev//ttyUSB0.  Not gone further than that.
A good start might be to 'sniff' the serial data using original Windows software and see what the protocols are but that needs an older window machine if the software won't run on Win7

Hi Dick I am not sure about this but the h/h DMMs that I saw with RS-232 interfaces did not transfer ASCII characters to the PC but a code" based on which segments of the 7-segment dispays were "lit". You will need the supplied s/w to interpret this so you may be stuck with what facilities this provides. It is probably no impossible to reverse engineer the code, but I dont think you were intending that.

Re: Using QRP Labs Ultimate Relay Kit and Low Pass Filters for WSPR

John G8BPQ
 

Tim,

I believe 50 mA is the current you can draw from the 3.3V power pins. It says this about the GPIO pins

GPIO input hysteresis (Schmitt trigger) can be on or off, output slew rate can be fast or limited, and source and sink current is configurable from 2 mA up to 16 mA. Note that chipset GPIO pins 0-27 are in the same block and these properties are set per block, not per pin. See GPIO Datasheet Addendum - GPIO Pads Control. Particular attention should be applied to the note regarding SSO (Simultaneous Switching Outputs): to avoid interference, driving currents should be kept as low as possible.

I found this site that gives the power limits of the GPIO: http://elinux.org/RPi_Low-level_peripherals and it says this:

Power pins

The maximum permitted current draw from the 3.3 V pins is 50 mA.

Maximum permitted current draw from the 5 V pin is the USB input current (usually 1 A) minus any current draw from the rest of the board.[15]

  • Model A: 1000 mA - 500 mA -> max current draw: 500 mA
  • Model B: 1000 mA - 700 mA -> max current draw: 300 mA

Be very careful with the 5 V pins P1-02 and P1-04, because if you short 5 V to any other P1 pin you may permanently damage your RasPi. Before probing P1, it is a good idea to strip short pieces of insulation off a wire and push them over the 5 V pins are not accidentally shorted with a probe.

So it looks like 28mA falls within the limits.
