Buildscripts used for ongoing development of Socfpga Debian bootable image(s).

Updated for Rel_2-1 release.

Current buildscript is:

SD-Image-Gen/build-all.sh

Featuring:

u-boot 2018:01

Cross compiled debian packed 4.9.76-rt61-ltsi kernel (providing devicetree dtb , dts , zImage, extlinux)

added kernel .deb package gen, including full range of socfpga .dtb(s) in /boot/dtb folder

ramdisk boot with uInitrd auto update (not tested)

including /boot/extlinux (to autoselect kerned on apt update)

Current rootfs = qemu-debootstrap generated rootfs (Debian stretch 9.x)

Howto build process:

For the full functionality setup a local debian repository (reprepro) and point the variable: HOME_DEB_MIRR_REPO_URL to its url (https://github.com/the-snowwhite/soc-image-buildscripts/blob/master/SD-Image-Gen/build-all.sh#L37)

clone the repo somewhere (in this example: /home/mib/Developer/the-snowwhite_git):

git clone https://github.com/the-snowwhite/soc-image-buildscripts.git

Create a new folder and cd into it:

mkdir Machinekit_image_build
cd Machinekit_image_build

see build script options:

/home/mib/Developer/the-snowwhite_git/soc-image-buildscripts/SD-Image-Gen/build-all.sh 

Bufore running the first builds install build dependencies:

/home/mib/Developer/the-snowwhite_git/soc-image-buildscripts/SD-Image-Gen/build-all.sh --deps

latest 2 sd-images are built with following commands:

uboot:

/home/mib/Developer/the-snowwhite_git/soc-image-buildscripts/SD-Image-Gen/build-all.sh --uboot=de0_nano_soc

kernel:

/home/mib/Developer/the-snowwhite_git/soc-image-buildscripts/SD-Image-Gen/build-all.sh --build_git-kernel=stretch=de10_nano

for the next command to work you need to have setup a local debian repo (reprepro):

/home/mib/Developer/the-snowwhite_git/soc-image-buildscripts/SD-Image-Gen/build-all.sh --gitkernel2repo=stretch=armhf

rootfs:

/home/mib/Developer/the-snowwhite_git/soc-image-buildscripts/SD-Image-Gen/build-all.sh --gen-base-qemu-rootfs=stretch=armhf

/home/mib/Developer/the-snowwhite_git/soc-image-buildscripts/SD-Image-Gen/build-all.sh --gen-base-qemu-rootfs-desktop=stretch=armhf

final rootfs setup:

/home/mib/Developer/the-snowwhite_git/soc-image-buildscripts/SD-Image-Gen/build-all.sh --finalize-rootfs=stretch=machinekit=armhf

/home/mib/Developer/the-snowwhite_git/soc-image-buildscripts/SD-Image-Gen/build-all.sh --inst_repo_kernel=stretch=armhf=machinekit

install kernel from local debian repo (reprepro):

/home/mib/Developer/the-snowwhite_git/soc-image-buildscripts/SD-Image-Gen/build-all.sh --inst_repo_kernel-desktop=stretch=armhf=machinekit

/home/mib/Developer/the-snowwhite_git/soc-image-buildscripts/SD-Image-Gen/build-all.sh --inst_repo_kernel-desktop=stretch=armhf=machinekit

Generate final compressed sd-card images with .bmap file and md5sum

/home/mib/Developer/the-snowwhite_git/soc-image-buildscripts/SD-Image-Gen/build-all.sh --assemble_sd_img=de10_nano=stretch=machinekit

/home/mib/Developer/the-snowwhite_git/soc-image-buildscripts/SD-Image-Gen/build-all.sh --assemble_desktop_sd_img=de10_nano=stretch=machinekit
