Create an SD Dard Image for Debian on Sidia Macnica

Create an SD Dard Image for Debian on Sidia Macnica

prerequisition

Build linux 4.4.52 kernel and debian 8 root file system based on this page.

Extract boot loader & u-boot from sodia image file

Our goal is to make a minimum debian system on Sodia board for fast data acquisition system development.  It can be re-used for boot process files by copy from RocketBoard.org provided file.

Download SD image file sodia_sdimage_ACDS16.1_REL_GSRD_PR.tgz from https://rocketboards.org/foswiki/view/Documentation/MacnicaSodiaEvaluationBoard

tar xvf sodia_sdimage_ACDS16.1_REL_GSRD_PR.img.tgz
sudo fdisk -l sodia_sdimage_ACDS16.1_REL_GSRD_PR.img

Make SDCard image

dd if=/dev/zero of=sodia_debian.img bs=1M count=2048
sudo losetup -f sodia_debian.img

sudo fdisk /dev/loop0

Make partition table as below -- create p3 first with type a2, then p1 with type 'b', and then p2 for rest of all blocks.
