To clarify the SD block driver is available, it's in the kernel source
code.
ftp://ftp.embeddedarm.com/ts-arm-linux-cd/sources/tskernel-2.4.26-ts11-src.tar.gz
In linux24/drivers/block/sdcard.c.
Although you'll find sdcard.c includes sdcore.c, sdcore.c is not
distributed with the kernel. The file sdcore.c implements the read,
write, and initialization routines for the SD card. The reason
Technologic Systems can not distribute sdcore.c is the SD association
requires all members sign a document stating they will not release any
source code or documentation on the proprietary SD spec. Therefore
Technologic Systems hands are tied with regard to releasing the low
level source code for reading, writing, and initializing the SD card.
Although Technologic Systems has released an OS independent
library(sdcore.o). One can compile our Linux 2.4 SD card driver with
this library, they could also write a driver for any OS(including 2.6)
with this library. A well documented header file describing the sdcore.o
library can be downloaded here ftp://oz.embeddedarm.com/sd/sdcore/sdcore.h.
I'll see if we can setup a meeting to discuss your recommendations with
regard to changing the documentation on our website. Thanks for your
input, we are not trying to mislead anyone. The last thing we want to do
is to upset our customers. ;)
