Can anybody help please?
My RaspberryPi turned up this week. I ordered it along with 2 8GB SD cards and some other bits and pieces. I downloaded a couple of disc images but I have been unable to write them to the cards.
I have a multi-way adapter and when I plug that into the USB port either on the front or rear of my machine I can check the hardware config. That shows USB SD Reader as sdc.
But when I try to write the downloaded image to /dev/sdc I get an error message :- sd 4:0:0:0: Device offlined - not ready after error recovery That's followed by this :- gs[26282]: segfault at 0 ip 00007effdb5dc470 sp 00007fff76b3c3c0 error 4 in libgs.so.9.02[7effdb3c9000+5f2000]
What software are you using to write to the card?
I'm trying to use the dd command.
Ah, yes I saw that there were descriptions of how to do it using dd but it's *much* simpler to use an application made for the job like unetbootin. This is what I used and it's pretty foolproof (and I'm the fool, sometimes).
But (there's always a 'but' ;-)), I have now googled the problem some more and found out that instead of relying on what the system is telling me, I should use the fdisk command. I did that, using 'fdisk -l' and it tells me that the card is /dev/sdg!
Yes, I think I used 'fdisk -l' to check. You need to be very certain as you don't want to go scribbling on disks without being *very* sure where you're writing!
I'm unsure that what I'm being told there is true however as it tells me whatever card I put in, be it 8 or 16GB is 32GB. Despite that I thought I'd persevere.
You tend to get the same device every time, unless you plug more than one in of course.
I have now managed, I *think*, to write the images but when I hook up the Pi to my TV, I don't get anything on the display. Although I can see LEDs illuminated on the Pi itself, I don't get any output on the tv and nor do I see any LEDs illuminated on the keyboard.
You should be able to see the files if you plug the SD card into your computer (where you wrote it). I've just plugged in one I created for my Raspberry Pi and the root partition has:-
chris$ cd 9DCF-4197 /media/9DCF-4197 chris$ ls -l total 16872 -rw-r--r-- 1 chris chris 17764 Nov 5 15:50 bootcode.bin -rw-r--r-- 1 chris chris 142 Sep 18 13:52 cmdline.txt -rw-r--r-- 1 chris chris 1184 Oct 12 15:16 config.txt -rw-r--r-- 1 chris chris 5282 Nov 5 15:50 fixup.dat -rw-r--r-- 1 chris chris 2020 Nov 5 15:50 fixup_cd.dat -rw-r--r-- 1 chris chris 137 Sep 18 14:40 issue.txt -rw-r--r-- 1 chris chris 2695192 Nov 5 15:50 kernel.img -rw-r--r-- 1 chris chris 2104952 Nov 5 15:50 kernel_cutdown.img -rw-r--r-- 1 chris chris 9522048 Nov 5 15:50 kernel_emergency.img -rw-r--r-- 1 chris chris 2347828 Nov 5 15:50 start.elf -rw-r--r-- 1 chris chris 523144 Nov 5 15:50 start_cd.elf
My next thought was that if I've written the images correctly, I should now be able to read the cards, but I can't.
Well you should, see above.
I'm not sure if the Pi will provide output on the composite connector as well as, or instead of the HDMI connector. I don't have an HDMI equipped tv so I'm having to rely on composite inputs. My next step is to check to see if the Pi should provide composite as well as HDMI output be default or if I would need to do something.
So it's off to google I go.
I can't help much there, I don't think I've got anything that can understand composite video any more! :-)
