I have brought one 8M M- systems MD2802-D08 ( 32 pins) I wish to apply to PHILIP 2106 arm system. which data lines I should apply?
would u please show me how to make use of the storage? need schematics and connection graphic ....etc, advices. I wish to expand its capacities.
just a newbie. TIA

I don't know what expansion bus your ARM system uses, but I'd suggest you get a carrier board for the disk-on-chip to suit and use that instead of trying to reinvent a square wheel.

The 2106 does not have a data bus. You would need to use the GPIO pins and make a psudo-bus and bit-bang the control signals.
Do you have a data sheet on the MD2802-D08 ???
apply
schematics
page 8 of
please tell me more.
Get the ARM-based evaluation board.
Cheers.

No ext buses on the Philips parts. I wonder exactly how Mylinux (with or without the N) acquired his brain damage. He really ought to be stuffing crayons up his nose under expert supervision, not posting reams of tripe* here.
please tell me more again.
Oboy,
Well first, are you a software or hardware person ?
The hardware: there are 13 address lines, 8 data lines, and 3 control lines. You will need 24 lines from the 2106 to connect to the DOC module. 16 output lines, and 8 bi-directional lines.
If you do not understand what this means, please find someone who does.
The software: On page 10 of said pdf is a memory map of the above hardware interface. From page 11 to the end of the pdf is how you would talk to the DOC module.
With the basics out of the way, how do you want to use this ??
If you want to just read/write blocks on the module, there is enough information here to do just that.
If you want to get a FAT compatable files system running, you are in for months of work. ( software mostly )
There are folks here who have implemented FAT files systems on CF cards and other media. They will tell you that this is not a beginner task.
If you have any resources (i.e. money ) to get this project off the ground, I would suggect you contact, google is your friend, a software library vendor who has FAT file systems for sale. ( U.S. Software comes to mind, but I have never used them )
good luck
direct mail is I before E
the hardware part is ok to me after reading the schematics.
the software is still very unclear.
Well thats the part that will take months of research and testing.
google for FAT12/FAT16 and FAT32
Good Luck.
