    Hi,

    I'm trying to run OpenVPN on the Neo but I think the kernel is currently lacking tunneling support.
    Where can I download the kernel sources and configure / build / install a new kernel ?

    For the Dual / Quad it was possible to build the https://github.com/UDOOboard/Kernel_Unico kernel from source, but I guess the Neo is running a more recent 3.6 based kernel.

    Are these sources hosted somewhere and can they be configured / built / installed much like the ones for Dual / Quad ?

    Thx ... I'm trying to add module support (DEVICE DRIVERS > NETWORK DEVICE SUPPORT > UNIVERSAL TUN/TAP DEVICE DRIVER.) but I'm unable to compile the kernel.... Any ideas ? (I'm following the instructions for the udoo dual / quad as I didn't find anything on the udoo neo).

    Code:
      Kernel: arch/arm/boot/Image is ready
  Building modules, stage 2.
  Kernel: arch/arm/boot/zImage is ready
multiple (or no) load addresses:
This is incompatible with uImages
Specify LOADADDR on the commandline to build an uImage
make[1]: *** [arch/arm/boot/uImage] Error 1
make: *** [uImage] Error 2
make: *** Waiting for unfinished jobs....

    I managed to build the kernel using zImage.

    By specifying UIMAGE_LOADADDR I could build the kernel but I couldn't get it to boot. Building zImage did the trick.

    Code:
    make -j4 uImage UIMAGE_LOADADDR=0x10008000  modules > ~/build.log 2>&1


scripts/kconfig/conf --silentoldconfig Kconfig
  CHK     include/config/kernel.release
  CHK     include/generated/uapi/linux/version.h
  CHK     include/generated/utsrelease.h
make[1]: `include/generated/mach-types.h' is up to date.
  CALL    scripts/checksyscalls.sh
  CHK     include/generated/compile.h
