(newbie) Compiling "linux-2.4.27-vrs1-ATMEL" for a custom board..what options should i provide?

Hi,

Im an undergrad working on installing Linux on a custom development
board based on the AT91RM9200 (for my senior project). Since this is
the first time im doing this, i decided to go for the
"linux-2.4.27-vrs1-ATMEL" kernle available from the Atmel site.
Incedentally, this kernel is built for the AT91RM9200-EK.

But i was befuddled when it came to "make menuconfig"..what are the
options that i must provide?? which are the options i must choose, and
which ones should i leave out? Can u guide me some pre-existing
".config" files?

The board in question has the following components:
AT91RM9200
16MB SDRAM (MT48LC8M16A2)
8MB DataFlash (AT45DB642)
32k TWI EEPROM

One USB device port
One USB host port
One PS/2 port

Serial Interfaces.

Thanx in anticipation,
Mayank

I was undergrad that does embedded linux on VIA EPIA for my final
project/thesis ( Thank god it's all done now...=p). I think I can help
a little

When you download "linux-2.4.27-vrs1-ATMEL" kernel, do you get
something like "linux-2.4.27-vrs1-ATMEL.config" file ?

The result of "make menuconfig" is  a ".config" file. It's filled with
kernel configuration that you make in "make menuconfig".

To use it, rename "linux-2.4.27-vrs1-ATMEL.config" to ".config"
(remember the dot before "config"), then do "make oldconfig".

Or if you dont like it, try "make menuconfig". Then in the bottom of
menuconfig, you can see option " load configuration file" (or something
like that, I dont remember it precisely). Enter the full path and
configuration filename (eg
/home/kunil/workspace/linux-2.4.27-vrs1-ATMEL.config).

If this not work, post more infos in here. Also post what you're
expected with your kernel. In linux world, you're the boss. So you
decide what your kernel do for you.

The obvious option is : set processor to "arm". Thus, you need to know
how the dataflash&eeprom is connected (using USB, IDE-CF converter,
etc).

If they are connected using different bus from regular PC (such as IDE,
PMCIA, PCI, ISA, etc), you need to make its driver by yourself (or
search someone who already made it). This one goes to TWI / I2C
connection. I'm not sure linux have driver for TWI / I2C.
