Cannot get a Raspberry pi to boot

[Don Lancaster]

Still cannot get the Raspberry pi to work after several frustrating tries.

The memory card was bought from a pi specific source.
Reloaded it twice. Specifically initialized the card.

NTSC Video monitor flashes a time or two.
Shows Nikon camera video just fine.

Waiting a long time on boot makes no difference.

Memory card shows the full 1.8 gigs uncompressed size.
2 gig card does not have its class posted on label.

Windows 8 makes running the checksum check difficult.

Removing the wireless mouse and keyboard before boot makes no difference.

Power supply is for a Motorola cell phone micro USB and seems to look
and behave reasonably.
Actual current unknown. Red LED lights quite bright.

Next, the power voltage will be checked and an oscilloscope used to see
what if anything is on the video output.
And a class 10 full 4 gig card will be tried.
Also the first few hundred K of the memory card will be separately read
for reasonableness.

The pi itself came from Allied Radio new and is not particularly suspect.


Help!

Help!

I believe you should be able to connect a 3.3V serialport, such as an
FTDI
to pins on one of the connectors and get a console in/out

Try installing a *proper* operating system on it; one of the Linux flavours developed for it, preferably!

I tried using their recommended "Wheezy" operating system.
Straight from the downloads section of their website.

As cheap as they are... buy another unit, and then debug the first.

Un bel giorno Don Lancaster digitò:

NTSC Video monitor flashes a time or two.

When you power on the board, do you see some activity for 1-2 minutes on
one of the LEDs (it should be the one for the SD? If not, I would try
another SD and if it still doesn't work I'd RMA the board. If yes, try
this:

1) Connect the ethernet port to a DHCP-enabled network and check if the
address is assigned (you can use nmap or any another network scan utility)
and the board pings correctly;

2) Try with the HDMI output. The analog output is crappy anyway.

Only the power led lights continuously.
The other led's remain dark.

Voltage measures 5.01 on the output connector.

Don--

Check the voltage across tp1 and tp2 on the RPI board; it should be
5VDC steady. The number one problem with RPI systems seems to be power
supplies that can't deliver. Particularly the early boards are prone
to hang or spontaneously reboot as USB devices are connected or started
up, pulling down the +5 rail.

Find a Class IV 2GB card and install Raspian from the Raspberry Pi
website on it. I have a couple of Class 10 cards that refuse to boot
on the RPI, but the Class IV cards work fine!

Try video from the HDMI output rather than the NTSC one, if possible.
That should show you more about the startup sequence and what progress
is being made.

If you don't have something HDMI (or a DVI device and a HDMI to DVI
cable), look at the "config.txt" file on the boot volume.

You should see:

sdtv_mode = 0

which selects NTSC (as opposed to PAL), and then remove the # in front
of the line so you have:

hdmi_safe = 1

which sets things for maximum HDMI compatibility.

This stuff and more is described at: http://elinux.org/RPiconfig

I hope this helps -- and I hope there's another RPI user or three local
to you who can bring a working setup by and help you through the throes
of startup. It can be a pain.

And thanks for all your contributions over the years (decades!) -- you
helped give me the bug, and helped me pass it on to my kids.

Voltage measures 5.01 at the expansion connector.
Using a 2GB card from a pi source with Wheezy.
No leds ever light except for red power.

Still cannot get the Raspberry pi to work after several frustrating tries.

The memory card was bought from a pi specific source.
Reloaded it twice. Specifically initialized the card.

NTSC Video monitor flashes a time or two.

Is this an NTSC specific boot image?
RPi comes from UK and (antique) TVs speak PAL there.

I have not tested the analogue video output on my RPi for all I know
it it turned off until configured.

I'd suggest gettign a HDMI or HDMI to DVI cable and connecting it to a
more modern display

After booting is the USB live? (eg: does numlock work)

AIUI booting it will change the contents of the card, The debian image
changes drastically on first boot.

Help!

Oh - it's windows. Most of the dd based utilities for Windows suck ass
in general.

I did find a little utility that did the trick though. It's calle
Flashnul. Lets you wipe and then image the card without issues.

Try that!

this is the famous author Don Lancaster? unreal ! cmos cookbook etc?
I used your books till the bindings gave out.

here I was thinking about a raspberry pi myself but if you can't get it to boot, forget about it.

I'm a fan, Don.
