SanDisk Extreme 8GB report.

Sun Jun 03, 2012 10:48 am

I bought SanDisk Extreme 8GB 30MB/s class 10 BI1118216254G (of course you can't know serial number unless you open box and get card in your hands).

R-Pi behaves the same with and without card. Power red LED is on but no activity on green LED. Monitor is blank :(.

I used Debian Squeeze from download section and also updated version from GitHub.

There are other not working cards reported with similar serial number BI*****16254G (btw. can anybody add mine SN to not working cards list?)

[My R-Pi is tested and working fine with 8GB MicroSD HC class 10 card form Adata.]

My questions are:
- was anybody in the same situation and managed to work this out?
- is there any hope that after doing something my card will start to work?

What to do now? Go to shop, buy another one, test is. Then go to shop, buy next one, test it? It is waste of money! :( Opened and used SD cards can't be return to shop.

Thanks,
Arthur.
PS: On veryfied cards list I see that thare are many Kingston cards reported as working (even 8GB class 10!) and only one reported as not working. Would you suggest to start buying Kingston cards?

The wiki page says on some SanDisk cards "Doesn't work with stock debian6-19-04-2012 image, but does work with freshly compiled kernel".

Sooooo.. I would say there's still some hope. Is compiling your own kernel beyond your skills? Alternatively you could try if the Arch Linux image boots..

Thank you for your answer.

I used latest (realesed 3 days ago) files from Debian Squeeze, GitHub.

I wonder if somebody had success having blank screen before.

Yes, I am not so experienced to complile kernel.
But even if I try - will be in somehow diffrent that those *.img and *.elf files at GitHub?? If yes - would you do compilation and send me those files? :)

I could try. Actually I already tried, but my poor server ran out of disk space while pulling the source code from git. :lol:

I'll give it a shot with my laptop.

-- EDIT --

Ah, right, you mentioned you already tried to get the most up to date kernel from Github ( https://github.com/raspberrypi/firmware ... aster/boot ).. I think compiling your own will not help in this case then..

Hmm.. anyone else got some ideas?

Once again thank for your help!! :)

I wonder if is it possible to go from blank screen (and not flashing green LED) to full workable R-Pi.

I know that "mmc timeout waiting for interrupt" problem can be solved using newest kernel, but I didn't find any information that going out from blank screen is possible.

Thank you,
Arthur.

ArchLinux (archlinuxarm-29-04-2012) tested.

Power red LED on, faint green (not flashing), blank screen :(.

Now I tested:

SanDisk Extreme (HD Video) 8GB class 10 30MB/s (BI1117216256G).

It does not work :(.

This card has the same serial number and paramters as mine (described in first post).

Just to confirm, same problem here:

SanDisk Extreme (HD Video) 8GB class 10 30MB/s (BI1201416254G)

No reaction whatsoever, doesn't even get to load the kernel, blank screen, no LED activity.

SanDisk seems to be a hit and miss. One of my old ones, SanDisk Ultra II Class 4 15MB/s boots the kernel but dies with a kernel panic. This might be solved with a new kernel/firmware but haven't tested.

...
So R-Pi behaves like without card.

Maybe it is bootloader bootloader issue? (but for now I know nothing about bootloader's things, is there anything like Broadcom bootloader?)
