Kernel reconfiguration with menuconfig

Other Parts Discussed in Thread: AM3517

Hello all,

I have craneboard with AM3517 and i'm trying to enable mouse in matrix-gui.

I follow next manual: http://processors.wiki.ti.com/index.php/How_to_use_a_Mouse_instead_of_the_Touchscreen_with_Matrix

My steps are (all executing from craneboard-kernel dir):

1. make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm distclean

2. make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm am3517_crane_defconfig

3. make CROSS_COMPILE=arm-none-linux-gnueabi- menuconfig

3.1 Select  "Load the alternate configuration file" and choose created by am3517_crane_defconfig .config file.

3.2 Make nesessary change in configuration and press "Save the alternate configuration file". Save configuration in the .config

When I compare .config file generated by am3517_crane_defconfig and .config file, changed by menuconfig I see, that it is absolutely different files. :(

When I build Kernel with: make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm uImage

I get next message (and many many questions followed by):

scripts/kconfig/conf -s arch/arm/Kconfig
*
* Restart config...
*
*
* System Type
*
MMU-based Paged Memory Management Support (MMU) [Y/n/?] y
ARM system type
  1. Agilent AAEC-2000 based (ARCH_AAEC2000) (NEW)
  2. ARM Ltd. Integrator family (ARCH_INTEGRATOR) (NEW)
  3. ARM Ltd. RealView family (ARCH_REALVIEW) (NEW)
> 4. ARM Ltd. Versatile family (ARCH_VERSATILE) (NEW)
  5. Atmel AT91 (ARCH_AT91) (NEW)

...

What I do incorectly?  I assume that I use menuconfig incorectly, and cant change existing .config file created by am3517_crane_defconfig.

Thanks and regards

P.S. Sorry for my english. It is not my native language.

    Hi,

    Can you review your config file and check that am3517_crane_defconfig exists in arch/arm/configs dir ?

    am3517_crane_defconfig - exists in  /arch/arm/configs

    1. def.config - file, that was generated by make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm am3517_crane_defconfig

    They look like a completely different config files.

    if you do menuconfig like that 'make CROSS_COMPILE=arm-none-linux-gnueabi- menuconfig' you can try also add 'ARCH=arm' - but it is a guess.

    Thank you! Promblen is fixed.

    I used command: make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm menuconfig

    Hi ,

    I have also created my uImage for the same kernel (linux-3.6.6) but i am confused  about the U boot and x-loader modifications and source code  . Can anyone help me on this .

    my uImage for the same :

    Image Name:   Linux-3.6.6
    Created:      Fri Nov 16 11:49:39 2012
    Image Type:   ARM Linux Kernel Image (uncompressed)
    Data Size:    2350520 Bytes = 2295.43 kB = 2.24 MB
    Load Address: 80008000
    Entry Point:  80008000
      Image arch/arm/boot/uImage is ready .


    Thanks & Regards,

    Ruchin

    Hi,

    I think that you do not have to worry about u-boot and x-load if you change kernel version. If you have kernel ie 2.6.x and want to  migrate 3.x you should take care about your kernel config and board file.  If you think that have problems in u-boot and kernel compatibility , try to turn low level logging in kernel config.

    Hi Karol ,

    Thanks for the quick reply i have got u boot and x-loader successfully compiled with the help of 

    http://processors.wiki.ti.com/index.php/Building_images_for_CraneBoard .

    I have also turn on kernel  low level kernel logging in Kernel Config file .

    Regards,
