w1302-HD Making SD Card

w1302

for ALL card:

1. enter work dir

   cd ~/sd_files/20160331/

2. set argument for burn disk.

   edit burn.config file to have these lines:

   # device node root name, to be partitioned
   device=/dev/sdc
   # directory where system automounts the partitions into
   mountroot=/media
   # tarballs to be installed
   BOOT=repack-boot-20160331.tgz
   ROOTFS=repack-rootfs-20160331.tgz

for new card:

./burn-stage01-newcardonly
./burn-stage02-rewritecard

for partitioned card:

./burn-stage02-rewritecard
