how to enable mmc card ?

jabka · 01-29-2007, 02:46 PM

Good evening ,...
i have acer 5102 wlmi with debian unstable
i have loaded the next modules :

Code:

shdci
mmc_block
usb_storge

but im unable to see any events when i plug in cards :

Code:

sdhci: Secure Digital Host Controller Interface driver, 0.12
sdhci: Copyright(c) Pierre Ossman
sdhci: SDHCI controller found at 0000:06:04.2 [1524:0550] (rev 1)

ACPI: PCI Interrupt 0000:06:04.2[B] -> GSI 23 (level, low) -> IRQ 233
mmc0: SDHCI at 0xc0202800 irq 233 DMA

but no events appear in dmesg .

the kernel is :
2.6.18-3-k7

and my lspci:

thnx you in advance ..

OK loading modules is fine. Now you have to create devices to access it. It you have a recent kernel it should automatically create some devices.

1. Load module
2. insert a SD/MMC card
3. Check dmesg - it should show some devices with names like /dev/sda1 /dev/mmcXXXX something like that.

Alternatively, see:

as saud in the first thread:
after inserting an sd card no new events.
also no /dev/mmc*

thnx anyway ...

It might be that Linux doesn't support certain kinds of flash memory at all.

I have an external USB card reader. I can read CF cards just fine, but never had any luck with MMC. MMC works fine when I connect it to my Powerbook.

Something to try ... I found that even though the default modules loaded after enabling them in the kernel (mmc_core and sdhci) I also had to load mmc_block. As soon as I did that dmesg showed a block device and partition added. Was able to mount it and use it with no problems.

sdhci: Secure Digital Host Controller Interface driver, 0.12
sdhci: Copyright(c) Pierre Ossman
sdhci: SDHCI controller found at 0000:03:01.2 [1180:0822] (rev 17)
ACPI: PCI Interrupt 0000:03:01.2[C] -> GSI 17 (level, low) -> IRQ 18
mmc0: SDHCI at 0xdfcfc700 irq 18 DMA

(this appeared after loading mmc_block)

mmcblk0: mmc0:e624 SD512 495488KiB
mmcblk0: p1

Good luck. I'd been waiting for a while for support for my chipset.
