No offence intended but it sound like you need to pick up a few good
Linux administration and either some C programming or bash scripting
books and read up on the basics :) What Jim is saying is all the
functionallity you need is already there in the OS/kernel. You can
partition a sd card with fdisk, create a filesystem with mkfs and mount
it with mount, these procedures will be covered in any decent Linux
book. To get data from a SPI interface you'll probably need to write
some code, that's where either a C programming book or bash scripting
book comes in (with some C helper programs to actually interface to the
SPI bus)
All in all, we can tell you how to do what you want, but it would mean
us basically doing the job for you (step by step) and take up a pile of
email messages :) and in the end, odds are you wouldn't have learned a
thing.
