Subject: Using SD cards on Samsung S3C2410/S3C2440 based systems
Date: Tue, 15 Dec 2009 14:43:59 +0100 [thread overview]
Message-ID: <200912151443.59761.jbe@pengutronix.de> (raw)
Hi,
has anyone experience with SD card usage on Samsung S3C2410/S3C2440 CPU based
systems?
I tried with:
- a very old Canon SD Memory Card SDC, 16 MiB
- SanDisk SD, 512 MiB
- SanDisk Micro-SD with adapter, 512 MiB
- Transcend SD ultra, 1 GiB
- Kingston Micro SD with adapter, 2 GiB
- hama SD Class 2, 2GB
- MMC plus, extreme memory, 2 GB
- Platinum SD 1, GB
I tried with a few kernels of the 2.6.31.x revision and 2.6.32.1, but most of
these cards are failing always.
The old Canon card works with every kernel. The others do not work with any
2.6.31.x revision kernel, but some(!) are working with 2.6.32.1 (both SanDisk
(512 MiB) and the Kingston Micro SD).
Kernel's output is most of the time:
s3c2440-sdi s3c2440-sdi: running at 0kHz (requested: 0kHz).
s3c2440-sdi s3c2440-sdi: running at 399kHz (requested: 400kHz).
s3c2440-sdi s3c2440-sdi: running at 399kHz (requested: 400kHz).
s3c2440-sdi s3c2440-sdi: running at 399kHz (requested: 400kHz).
s3c2440-sdi s3c2440-sdi: running at 399kHz (requested: 400kHz).

s3c2440-sdi s3c2440-sdi: running at 399kHz (requested: 400kHz).
s3c2440-sdi s3c2440-sdi: running at 399kHz (requested: 400kHz).
s3c2440-sdi s3c2440-sdi: powered down.
mmc0: error -110 whilst initialising SD card
s3c2440-sdi s3c2440-sdi: powered down.
The output for the "Kingston Micro SD" in kernel 2.6.32.1:
s3c-sdi s3c2440-sdi: running at 0kHz (requested: 0kHz).
s3c-sdi s3c2440-sdi: running at 399kHz (requested: 400kHz).
s3c-sdi s3c2440-sdi: running at 399kHz (requested: 400kHz).
s3c-sdi s3c2440-sdi: running at 399kHz (requested: 400kHz).
s3c-sdi s3c2440-sdi: running at 399kHz (requested: 400kHz).
s3c-sdi s3c2440-sdi: running at 399kHz (requested: 400kHz).
s3c-sdi s3c2440-sdi: running at 399kHz (requested: 400kHz).
s3c-sdi s3c2440-sdi: running at 399kHz (requested: 400kHz).
s3c-sdi s3c2440-sdi: running at 24978kHz (requested: 25000kHz).
s3c-sdi s3c2440-sdi: running at 24978kHz (requested: 25000kHz).
mmc0: new SD card at address 8d7e
mmcblk0: mmc0:8d7e SD02G 1.83 GiB
mmcblk0: p1 p2
Any idea why most of the cards do not work?
Regards
Juergen
