Attention: Kernel partition size has been enlarged to 4MB. To switch, you must update to latest ar71xx-nand snapshort and flash the sysupgrade-4M-Kernel.bin: zcat openwrt-ath79-nand-zyxel_nbg6716-squashfs-sysupgrade-4M-Kernel.bin | mtd -r -e ubi write - firmware; reboot -f You will end up with a fresh config if you do not inject config into the image. The NBG6716 may come with 128MB or 256MB NAND. ar71xx was able to use all, but ath79 can only use the first 128MB. Therefore the complete NAND needs to be overwritten. If not, the old UBI may make problems and lead to reboot loop. Access the real u-boot shell: ZyXEL uses a proprietary loader/shell on top of u-boot: "ZyXEL zloader v2.02" When the device is starting up, the user can enter the the loader shell by simply pressing a key within the 3 seconds once the following string appears on the serial console: | Hit any key to stop autoboot: 3 The user is then dropped to a locked shell. |NBG6716> HELP |ATEN x[,y] set BootExtension Debug Flag (y=password) |ATSE x show the seed of password generator |ATSH dump manufacturer related data in ROM |ATRT [x,y,z,u] RAM read/write test (x=level, y=start addr, z=end addr, u=iterations) |ATGO boot up whole system |ATUR x upgrade RAS image (filename) |NBG6716> In order to escape/unlock a password challenge has to be passed. Note: the value is dynamic! you have to calculate your own!

This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
