Hi Carsten,
one possibility is to write one long defragmented file with a 512 (one
sector) unique bytes as starting symbol to SD card using standard card
reader on PC. This is easy task - erase (better quick format) entire SD card
and write prepared file.
On your board you can only find start of this file - read sectors from
begining until you find starting sequence and next sector is basic adress
for your buffer.
On PC you can simply read this file.
Sorry, I forgot how this metod calls - it is not sclerosis but my inability
;-)

Hello,
I have some code running now on a Embedded Artists 2148 board that
accesses a SD card (based on the philips code). So I can read/write
individual sectors....
My plan is to use a SD card as a "circular" buffer for data, so I
won't be using a real "file system" like FAT16 etc.
What I need now is a simple program (or some ideas for it) that can
access a SD card when connected to a PC using "raw" sector access....
That way I will be able to read the data from the card when it is
inserted in a card reader in a PC.

Any ideas/pointers ?

Regards,
Carsten
