==Linux==

on Linux, write sdboot-header.img into beginning of your micro SD card. (you'll lose all data on it)

then, your SD card should have a 1GB FAT partition. format it, mount it, then put rksdfw.tag sd_boot_config.config, and Radxa's update image for SD card as "sdupdate.img" into root directory of SD card.

Download the binaries from http://files.androtab.info/radxa/sdboot.tgz, and unzip it.
    dd if=sdboot-header.img of=/dev/sdX bs=1M conv=fsync
    mkfs.vfat /dev/sdX1
    mount /dev/sdX1 /mnt
    cp rksdfw.tag sd_boot_config.config /mnt/
    cp path/to/radxa_update.img /mnt/sdupdate.img
    umount /mnt
