recompile kernel

Hi there,
I have Ubuntu linaro 12.04 installed on my udoo quad. I need to recompile the kernel. How can I do it?
Can I use the source at https://github.com/UDOOboard/Kernel_Unico ?

Thanks,
Davide

 

apt-get install build-essential libncurses5-dev
git clone https://github.com/UDOOboard/Kernel_Unico kernel
cd ~\kernel
make ARCH=arm UDOO_defconfig
make menuconfig # <---- add whatever
make -j4 uImage modules

 

Hi,
thanks for your fast reply.
After I compile, how can I test and execute the kernel?

Thanks,
Davide

 

Easy or hard depending on your situation !!!!!

You need to add uImage and the modules to the rootfs , which has not been use to boot from.
eg , boot from sd card and change the uImage and the modules on the sata drive , or a second computer running any form of linux, mount the drive and add the files

uImage goes in to /boot and the modules in to /lib and you should finish up with /lib/modules/3.1.2.3 etc

 

Hi,
Basically, I'd like to load the HID modules in the kernel, as described in:
http://learn.linksprite.com/pcduino/use ... n-pcduino/
:........... but I'm a newbie...............

Could you help me with the commands after "make menuconfig" ?

Thanks,
Davide

 

I`m waiting for my udoo to be returned , so I can`t tell you which modules to install or where in the menu system it is , But the HID , which is a mouse and keyboard should already be installed .

After looking at your link :-

I don`t think what you are trying to relevant to the udoo ?

 

Hi,
basically I'd like my Udoo can acts as HID mouse when it is connected to a computer via USB OTG. For this purpose, I need to enable HID modules in the kernel as described in the previous post.

Thanks,
Davide

 

I`ve seen the same thing using mbed , where a mbed become a HID controller , But you are wanting the multi-core linux side to become the HID controller .
