Hi Mike,

I use efsl_0_2_9_RC7_mt_20070903.zip from the page

http://www.siwawi.arubi.uni-kl.de/avr_projects/arm_projects/efsl_arm/

My Circuit is externaly wired sd/mmc connector with 10cm long wires ! But I have already worked o this hardware with another filesytem (sham176_ccfatlib) with the maximum SPI speed without any errors.

I also tried lowes SPI speeds for EFSL , but its still same.

Thanks

Try dropping back to 0.2.9.RC4, as there were some significant
changes in all of the low level SD code in that revision. I've
been using RC4 for a long time, and it works well, though
I have not used it much with 2GB cards.

Can some one give a pointer to=A0 a good Interface electronics cct for SD M=
MC. I got one that has a=A0 Zero ohm Resistor?
=A0
what value do I substitute /use there. (Just a short )?
=A0
