Updating kernel in ubuntu
Move the base ISO downloaded in the first step to the working directory.
From here on out, replace “ubuntu.iso” with the name of the image downloaded from the Ubuntu Release server ex.
This was particularly unfortunate as most common distributions (Debian, Ubuntu, Fedora, etc) standardized on the ARMv7-A architecture as a minimum for their ARM hardfloat ports.
The image is 3G, so should fit on any SD card marketed as 4G or bigger.If you’re like me, you’ve wanted to customize an Ubuntu install DVD for a long time – but all the tools/directions for doing it are out of date and/or broken. I have successfully customized an ISO of Xubuntu 14.04 for my project Builduntu but this guide should work for just about any flavor of Ubuntu, maybe even other Linux distributions. Mint and Debian are very similar and may work with minimal changes to the commands (ie, replace apt-get with whatever package manager the particular distro uses).It helps if the distro you want to customize is the same as what you are running currently, but is not necessary. First download the ISO you want to start customizing from Ubuntu’s release server.To get the source code, you have to clone the buildroot-at91 and buildroot-external-microchip repositories. remote: Total 571 (delta 217), reused 288 (delta 170), pack-reused 225 Receiving objects: 100% (571/571), 94.41 Ki B | 76.00 Ki B/s, done. $ ls buildroot-external-microchip/ board configs COPYING docs package patches system branch which is pointing to the latest version of buildroot-at91 and buildroot-external-microchip.buildroot-at91 is a fork of Buildroot with a minimal amount of patches, only the ones which have not hit the mainline yet. remote: Total 271126 (delta 0), reused 2 (delta 0), pack-reused 271124 Receiving objects: 100% (271126/271126), 61.00 Mi B | 2.36 Mi B/s, done. $ ls buildroot-at91/ arch board boot CHANGES legacy configs COPYING DEVELOPERS docs fs linux Makefile Makefile.legacy package README support system toolchain utils $ git clone https://github.com/linux4sam/Cloning into 'buildroot-external-microchip'...

Make sure the prerequisite software is installed for unpacking and repacking the image.
