micro sd card

cod_liver_0il · 06-06-2012, 12:08 PM

Hi, wonder if anyone could tell me how to find my sd micro card device name. I plug it in and dmesg, syslog and messages don't show anything? ...i was wondering if i was doing something wrong or my card reader has stopped working.

thanks.

BTW, the card reader is built into my laptop.

as root

Code:

fdisk -l

should show your sd as /dev/sdX (it uses SCSI emulation), you should recognize it easily by the size.

Code:

df -h

to see if it is (by any chance) already mounted.

No ponce, it's not mounted already i tried fdisk -l and df -h just shows /dev/sda

If you have no info in "dmesg" then I think your card reader is broken or unconnected. Which kernel version you have?

Please post the make/model of your laptop. Some laptop card readers have proprietary interfaces

My laptop is a Fujitsu Siemens Alimo and i'm using 13.37 stock kernel

What is the model number? ie. M7400, A1630 etc.

M7405

I could not find much information on the card reader. According to the link it isn't supported.

Note that if you have a micro-sd HC card, you would be better off to have a kernel > 3.0

I had exactly that problem when running the huge.s kernel. Plugged in an sd card and got nothing. No dmesg info or anything else to go on.

However, creating an initrd using the Slackware built in generator, and then running the generic kernel worked straight away and my card reader sprang to life. So it might be worth you trying that approach, although of course it may not work for you.

Hi vdemuth

What kernel are you using? I have exactly the same problem referred to in this thread, and so far I have not been able to fix the SD-Card thing. I boot using an initrd with an own-compiled kernel, using as source kernel 2.6.38.7 but with a slightly modified config file (based on that shipped with Slackware 13.37)

Jut wondering if maybe using a kernel > 3.X, with your initrd approach, works better to get the SD-Card working.

Exactly which type of card do you have?
