Installation (sd card ?) problems

Tue Sep 15, 2015 9:51 pm

Hi,

I just got my Pi2 today, but damn this sd card is giving me troubles. Its a transcend 16gb, class 10 card.

I tried the standard NOOBS procedure using SD Formatter, I tried WIN32 DiskImager using the Raspbian image, I slow formatted under windows and tried NOOBS again, all installation give me troubles.

For example with NOOBS:

After clicking ok it just hangs, when clicking ok with the shift button, it reboots. After reboot I get 7 blinks (7 flashes: kernel.img not found)

Then I tried Win32 Disk Imager and used the Raspbian .img from raspberrypi.org
I did get an initial config menu but after reboot it's this for 10 minutes:
Image
Image

When I reboot I get this:
Image
KERNEL PANIC : that cant be good :(

What is wrong here ? Damn I was kinda exited to get my first Pi up and running but this sucks :(

Thanks in advance

-a- check on the RED power LED if it blinks at startup ( low volt indication )
-b- check your SD card is bad listed here

-c- try a other SD card

a: Power supply is OK

Transcend microSDHC 16 10 TS16GUSDU1
Raspberry Pi B+ Model (tested on OpenELEC,xbian, raspbmc, kali linux) @xhark 05 Oct 2014


- I got it running after first booting up with no mouse, keyboard or lan
- Then I plugged in the LAN and remotely installed tightvnc
- Works fine

Now when I reboot I get errors like this:
[Mod Edit: Corrupt/Spam links deleted]

I have to unplug the LAN cable, no mouse, no keyboard connected. Only analog video output connected.
In this situation boot up is irregular:
- It might boot up fine
- I gives errors like above
- I unplug, wait a bit, boots fine

Do you think I should go back to the shop so they can give me a new SD card ?

Thanks

Yes, try a different SD card.

Well, I went back to the shop and the guy fixed it for me.

He was talking about the kernel that had to be updated:
viewtopic.php?t=113753

He told me that the Raspbian Wheezy image (2015-05-05-raspbian-wheezy.img) has an older kernel that doesn't work well with cards bigger then 8GB. He updated it to 4.1.7-v7+

All problems are gone and it boots up fine :)

I wonder if I believe that, not heard anything like that before.
Need more sources than one to believe it.

Well. what he told me :
- The img (2015-05-05-raspbian-wheezy.img) has kernel 3.something in may 2015
- This issue was found in june but they didn't update the downloadable image

That's what he told me, I don't know if it's bull or really the issue. But he seemed sincere.
Anyway, it's fixed now, several reboots later, I haven't had any problems.

Can anyone independently confirm that older 4.x.x kernels have problems with some SD-card sizes? I could then add that information to my boot problem sticky, but I need proof, especially as there are users that claim it is false!

I declare myself to be in the 'yet to be convinced' camp.

Note that the original post that initiated this thread relates to the inability of mkfs.fat, invoked from the NOOBS Installer, to correctly set up the filesystems on the card.

Of course, NOOBS has at its heart a stripped down linux shell. But if the kernel used by NOOBS has not been able to handle SD cards > 8Gb since May 2015 then:

1] Surely these forums would have been awash with requests for help and this pattern would have been spotted?

and

2] Updating the kernel used by an installed version of Raspbian would not affect the behaviour of the NOOBS Installer.

Either way, it would be nice if the Moderators could get someone with RPF 'Engineer' credentials to double check this and comment authoritatively one way or the other.

Definitely a case of "If you can't blind 'em with science, baffle them with bull".

The guy in the shop clearly sent out a RPi 2 with an SDCard that didn't include the right firmware to run a RPi 2.

This discussion seems to be a little over my head but... I did not buy a pre-installed SDcard.

- I bought : Rapsberry Pi 2 Model B 1GB
Image
EAN code 640522710515

- I bought: a blank SD card
Image


1.
I formatted the card and put noobs on it

Code: Select all

https://www.raspberrypi.org/downloads/noobs/
https://downloads.raspberrypi.org/NOOBS_latest
NOOBS
Offline and network install
Version: 1.4.1
Release date: 2015-05-11
That din't really work, gave errors like in my first post

2.
I formatted the card on both windows and mac using SD Formatter 4.0 - full erase/overwrite
Then I used Win32 Disk Imager on windows and PiFiller on my mac to write the image file for Raspbian:

Code: Select all

https://www.raspberrypi.org/downloads/raspbian/
https://downloads.raspberrypi.org/raspbian_latest

Raspbian
Debian Wheezy
Version: May 2015
Release date: 2015-05-05
Kernel version: 3.18
I tried all options I could think of: formatting, trying NOOBS, formatting trying Rapsbian, booting with keyboard and mouse disconnected, booting with only keyboard, booting with and without LAN, booting with nothing but the video connected...

All the above did not work and gave me irregular reboots.
What he told me was to rpi-update (or something) on he first boot of Raspbian Debian Wheezy.

Fact is that now:

Image

Everything is running fine, I got my Pi connected to my router, rebooted a lot and can happily connect using putty or tightvnc.
It just works now

Can't agree more. I have solved this after using another SD card.

well, unless independent conformation is released I won't add this "tip" to the boot problems sticky.

I've seen it work sometimes, a person may have gotten a bad card that won't work with the Pi, sometimes it's just broken down with the wear and tear, sometimes its been formatted so badly that it won't work again.

It's a little of a hit and miss, but it has proven effective in some cases.
