no /dev/sd** device appears when I plug in a card to the laptop's card reader
 

Hello there,
I have a Toshiba m40 185 laptop, with a Texas instruments card reader.
I compiled a custom kernel and have been trying to get the card reader to work.

when i plug in the xD card from my camera the kernel seems to get it right :

and lsmod returns the loaded modules:

still I don't see any /dev/sd** device. I only have a hard disk on /dev/sda

any idea what's going on with the tifm module?

Maybe you don't have a udev rule for it. Which distribution are you using?

If it helps, mine is /dev/mmcblk0 and my fstab have this line

sony ones still failing to read...

slack13.1 32bit

got nothing of the sort BrZ :(

do you have tifm_sd module?

edit: some info about tifm: http://openfacts.berlios.de/index-en...12/xx21_driver

actually no and I started getting curious why is it not loading since I have it compiled as module:

from .config

but after inserting the card in the card reader, I get to the point at which i started this thread....

BrZ I am not sure what to make of the link you sent me...

It seems abit old talking about kernels 2.6.22.. so what should I assume that the 'early development stages' for xD cards is now fully implemented?

Then again in kernel 2.6.35.4 i don't see any tifm_xd option when I fgrep exactly that. so maybe nothing is included in the latest kernel versions..

also, if you have any idea, why don't I see the tifm_sd module loaded?

What version of Slackware comes with a version 2.6.35.4 kernel?

none
i'm running slack 13.1 with a custom kernel

The 2.6.33.4 kernel does have a tifm_sd module. Look in /usr/src/linux-2.6.35.4/drivers/mmc/host/ for the file tifm_sd.c to see if there's one there.

Plus it's nice to mention things like "I'm using a custom kernel" when asking for kernel help. Just saying.

I am not sure what you mean by that, but if a feature exist in an earlier kernel it most probably is still there afterwards.

what i mean is that of course the tifm_sd module exist in kernel 2.6.35.4 and i have compiled it in as a module (see above for the .config print).

hello again! I'm ressurecting this thread cause I have searched alot for an answer on the matter of the tifm driver.

well first of all, if you enable the mmc_core, mmc_block, tifm_core, tifm_7xx1, tifm_sd modules in the kernel, you'll be able to access Sony SD and microSD cards (I have a couple lying around - 2GB and 8GB).

But I wasn't able to access a 1GB olympus xD card, however much I tried.
Apparently the tifm development team was building a new driver tifm_xD for the xD cards, but that was during kernel 2.6.21 or so.. here is the link http://openfacts.berlios.de/index-en...12/xx21_driver

So no lack on the xD end.

I guess the development has halted or is at least going toooooo slow (if there is nothing about tifm_xD in kernel 2.6.35.4)...

so that's pretty much it about this driver...
If somebody has managed to get an xD card to be read by the (lspci)

using the tifm collection of drivers or otherwise (perhaps with the sdhci drivers) please let me know.
Thank you
