I wanted to cross compile kernel for Beaglebone Omap3 but I could not find the Omap3 defconfig at arch/arm/configs.
Can anyone point me out which defconfig I need to use to get Beaglebone Omap3 kernel compile ?

I'm just curious if it is possible to compile a Linux kernel driver (* .ko binary) with only Linux kernel sources?
Is it inevitable to have a compiled Linux kernel to compile a Linux kernel driver?
Hello I have beagleboneblack board and have kernel source code I want to make my i2c work as a module so for that, I have done some changes in .config file
#
# I2C support
#
CONFIG_I2C=m
and cross compile kernel
make dtbs zImage -j8 CROSS_COMPILE=arm-linux-gnueabihf-
But after compile successfully, CONFIG_I2C change from 'm' to 'y'
how to solve this problem?
I use gcc myprogram.c -o myprogram -Wall -Werror to compile a program in fedora and then load the binary myprograminto the storage of a openwrt image that I'm running using qemu. Then in the openwrt image I try running the binary using ./myprogram, I get /bin/ash: ./myprogram: not found. How can I fix this?
You need to use a toolchain, to compile with the same libraries you have in your image (or compile it in QEMU if possible). Even if QEMU runs x86_64 as I suspect is on your host, you should use the toolchain (for example your host and OpenWRT can use different libc / musl version - OpenWRT mostly comes with musl library)
Please refer to this URL
Here you will find the toolchain for the latest stable OpenWRT image [19.07.1].
I will like to know how do the kernel builder to compile parrot modules while compiling the kernel.
I saw a config file for 2.6.32 that has the CONFIG_PARROT modules to yes. And I know where this modules files are stored on the kernel 2.6.32 source. I want a 2.6.37 kernel builder to make this parrot modules and add them to the kernel so I can use them on a VM.
Beside adding the path to the drivers source on the Makefile and setting the CONFIG_PARROT lines to the .config file of the kernel, is there something else to do?
I am trying to insert a .ko kernel module into the linux running in arm processor. I built a .ko file in my desk PC which is a x86 one. How do I cross compile it to arm specs. I am new to this field.
Thanks in advance
For that you need to download the ARM compilers first. I suggest you download the compiler from http://www.linaro.org/downloads/ then set the CROSS_COMPILE environment variable to arm-linux-gcc.
set the bin directory path in PATH variable.You can do it by export PATH=$PATH:/path/to/arm/binaries/
Finally compile the code then run in ARM.
use file <filename> whether it is ARM executable or not.
For this you have to do the following steps.
Check you have cross compiler tool chain or not.
If you don't have cross compiler tool chain
you can download from one of the free ARM cross compiler from net.
You can generate your own cross tool chain using Buildroot tool. below you can get the link of Buildroot user manual.
http://buildroot.uclibc.org/downloads/manual/manual.html#_using_buildroot
Install cross tool chain in your host PC.
Export the cross tool chain path in your host PC using export command.
Change the make file of the kernel module to set the compiler as CROSS_COMPILE.
Do make.
Move the .ko file to target and insert it.
