Default kernel config required

[subash_patel]

Hello,

I see below three configs related to raspberry-pi board. Can someone here confirm which is the default config to be used to build a kernel for type-b?

arch/arm/configs/bcmrpi_cutdown_defconfig
arch/arm/configs/bcmrpi_emergency_defconfig
arch/arm/configs/bcmrpi_defconfig

Regards,
Subash

arch/arm/configs/bcmrpi_defconfig is
but, this is the minimal set, you need to enable many other options as needed

Does 2012-08-16-wheezy-raspbian kernel's .config available ?

Just boot it up and:

Code: Select all

zcat /proc/config.gz

Thanks. That is cool.

Code: Select all

$ zcat /proc/config.gz > current-rpi-defconfig
$ cat current-rpi-defconfig

This bit of information is a true gem.
It and the following allowed me to finally build a kernel with the modules I need.
http://mitchtech.net/raspberry-pi-kernel-compile/

The new kernel is 5325476 bytes. The one from wheezy-2012-10-28 is 2695192.
I added only one module.
Any suggestions as to why this is so? I presumed the .config from the SD card would reflect the kernel contents.

Thanks,
Peter

The smaller kernel is the zImage (just rename it to kernel.img). It is compressed.

Anybody have a link to help determine what other options are needed? I was successful in building 3.6.11+ and it runs but now my SPI test program doesn't work. I used default config and pressed ENTER for all new configuration options to accept defaults, but I suspect there's more to it than that. Is there a list of what's needed for the "B" raspberry pi anywhere?
