RPi Will Not Boot Up

[punkhunter]

I'm new to the Raspberry Pi and so-so with Unix (let's say I'm still a beginner to be safe).

I am seeing a lot of errors when trying to boot up my device. I set up the SD card on Windows using the steps outlined (and I think I was pretty careful and detailed about the instructions). I downloaded the Raspbian Wheezy distro and compared the checksum to the one on the d/l page...they matched. Then, using the recommended application (Win32DiskImager) I got the img onto the SD card (unzipped of course). I hook up the HDMI, USB keyboard, insert the SD card and plug in the power supply. It comes up initially with a screen that looks like a color selector in paint shop pro or something, then goes to a command line screen with a raspberry at the top left. Tons of text just keeps scrolling and never stops. I keeps seeing a few errors over and over again. I've tried searching for them in the forums and looking at the "beginner help" on the wiki, but didn't see anything. RPi is brand new and so is the Duracell 16 GB class 10 SD card. Any help is appretiated! Here are the errors (not in particular order):

Timeout waiting for hardware interrupt - cmd 13

I/O error, dev mmcblk0, sector 389616

error -110 sending status command, retrying

Of course with a bunch of stuff in between these errors that don't make sense to me. BTW: my keyboard works (I can start typing in the command line, but it doesn't do anything that I can tell)

Maybe try manually copying over newer firmware? Copy over these files to the main folder of your SD card's boot partition (the only partition visible in Windows) https://github.com/raspberrypi/firmware ... aster/boot

I'm going to guess power supply, can you try a different one?

It could be anything plugged into your Pi.

For example take out the Ethernet and see if it boots... If that still doesn't work take out the mouse and see if it works.... etc. etc. etc.

Hopefully by the end of it you will be able to see what is throwing up those pesky errors!

While I'm still not sure what the problem is, as a helpful person, I'll dissect the main error message:

Code: Select all

I/O error, dev mmcblk0, sector 389616

mmcblk0 is the SD card... a problem talking to it (I/O) has to do either with firmware or power issues

I am concerned about the basic reliability of the RPi.

I've been using mine for about a week, and have seen error messages on the screen, but after rebooting, would see 'repaired' messages appear - so things have seemed to be fine.

I am rather careful with the shutdown process - I always 'sudo shutdown now' method.

Today, after typing 'sudo reboot' from a remote terminal (I'm using puTTY on a win7 pc), the bootup shows many errors, including password file not found...etc. (I'm running wheezy on a 8GB card, running python scripts (which are now possibly lost!), and using both a USB keyboard and networked in through my router and running puTTY on a win7pc).

So, I intend to re-image the card, but if anyone would like to see any files that are on the card to troubleshoot this, let me know - I'm not certain what I will be able to read off the card on my winpc.

I am most concerned as I was hoping to use the RPi as a highly reliable embedded system, but this rate of quality is unnaceptable for that application.

Any helpful advice appreciated.
Thank you,
TomC

Command 13 (SD_CMD_SEND_STATUS) is used to verify the cards status during writes.
My guess is your SD card is the problem.

First thing...thanks for the quick responses!

I have tried booting up with nothing but the power supply and HDMI connected, and the SD card in...same errors. I think I have a different power supply and SD card. I'll try those one at a time and report back.

SD card was it...I switched out the Duracell brand with an Amazon basic 32 gb class 10. Now it works great! Thanks again for the help!
