First time Can't boot my RP

[plocplic]

Hello everybody

I shall assume my lake of knowledge and ability (also my rude english : i'm french !)

I received a Raspberry pi from The Pi-Hut

I followed some tutoriels to my first boot but nothing happened : no video signal (the RP is plugged to a video screen with a video connection)

I read that maybe the SD card has not been properly fullfilled, I formatted it and downloaded NOOBS and followed the instructions, but still my RP refuses to boot...

I'm very sad... Does anybody have any idea ?
Any help would be very appreciated and remember to explain everything as if I were a 5 years old boy

Thanks

Hi, did you use the format tool at https://www.sdcard.org/downloads/formatter_4/?

Also the instructions http://elinux.org/RPi_Easy_SD_Card_Setup may help.

I went through this quite a few times before figuring out my SD card didn't work very well with the Pi. Another card solved my problems.

EDIT: trouble shooting boot problems: http://elinux.org/R-Pi_Troubleshooting# ... F_Start-up

Do have a good look through the R Pi hub at the elinux site. Much helpful advice there.

2nd edit: also see sticky post in this forum: http://www.raspberrypi.org/phpBB3/viewt ... 91&t=58743

The first thing to do is make sure you have an adequate power supply. What are you using to power your Pi?

Do any of the lights on the Pi flash when you plug it in? Which ones? Are there any patterns?

Have you looked at the following page?

Thanks for your answers

I wasn't able to check the voltage measure of my power supply but the power supply comes from The Pi Hut so it should be dedicated to the Rpi
I did have the red light, the green one (which flashed a little moment) and two orange ones...

The SD card also was from The Pi Hut, I formatted it because it was not working I followed the official instructions as carefully as I can...

I'll try again tonight

[plocplic]

So I just tried again

The red light is constantly on
The green flashed 3 or 4 times at the beginning but no more after.

I still don't have any video signal.

I've checked the SD card sent by The Pi Hut it's a Kingston 8Go / SD4

If I follow the link http://elinux.org/RPi_SD_cards
it's not so clear because there's two similar cards :

ok Kingston SDHC 8 4 SD4/8GB Works reliably with Raspbian 18-9-2012 and previous Debian releases (Picards) Md84419 5 Nov 2011, Picards 28 Oct 2012
nok Kingston SDHC 8 4 SD4/8GB does not work with current build of raspbmc (LastSilmaril), unreliable with raspbian (Quentinsf) LastSilmaril 24 May 2012, Quentinsf 20 Oct 2012

Maybe that's the problem, I don't know... The Pi Hut is serious, no ?

Please help me, it was my very first day with my Rpi !
Thanks

Try editing /boot/config.txt (F:\config.txt on windows)

Add
boot_delay=1
save the file and try it again in your RPi.

Dougie, thanks for your help

But I'm not sure to understand what I have to do, sorry my knowledge are very poor

My computer is a mac

If you can be little more precise, it would be very helpful

For the moment, I formatted again the card and I'm downloading the very late version of Noobs

[plocplic]

Ok time to get some rest...

Still no success

1/ I've formatted the card and downloaded the late version of NOOBS

2/ I've tried to follow the config.tx suggested by Dougie but maybe I've done wrong or have not understood what to do exactlyhttp://elinux.org/R-Pi_ConfigurationFile

3/ I've tried another SD Card I have (Sandisk 8gb/10/Ultra)

4/ I've tried another screen with RCA connection

I'm gonna drink a bootle of wine and tomorrow is another day...

NOOBS has just been updated to (hopefully) fix the "boot delay" issue (see the end of this long thread: http://www.raspberrypi.org/phpBB3/viewt ... 28&t=64330) . I don't think Kingston cards are a problem (any more - the elinux wiki info. is now quite old) - I use quite a few: http://www.cpmspectrepi.webspace.virgin ... cards.html . Using NOOBS with composite video is "tricky" as noted in my "screenshot-based guides" to the NOOBS installation process at: http://www.cpmspectrepi.webspace.virgin ... ellow.html (there is a "backlink" to HDMI-based installation there too).
Given that you have been seeing "green LED ACTivity", that suggests that the boot process is starting but, may be, not leading to a suitable video output for your display types.

Thanks for your answer

I'll try with a HDMI/VGA connection and my usual screen

You're welcome. FWIW, some notes on my trials of a HDMI to VGA adapter are here: http://www.cpmspectrepi.webspace.virgin ... erter.html
(there's a link to a few NOOBS 1.3.3 snapshots using it in the footnotes)

Hello everybody

I went out to buy a HDMI_DVI cable et now it starts

So my video connection was the problem. Do you think i can solve that problem because I would prefer using a small 7" screen rather than my computer's

Thanks anyway for your answers

Kinds regards

It's probably worth starting a new thread with some details of your 'small 7" screen' and ask for help/guidance therein.

If you are attaching a portable 7" screen I would guess that is a USB monitor and you will need to attach it to the Pi with a powered hub. Otherwise, it will take too much power and not work. Unless it is a composite monitor, but the Pi only has so many devices it can power and it might be worth investing in a device that measures the power so you can debug problems better. In the USA they are called multimeters.
