find resulting image under the following, where architecture is "ramips" ./bin//
* factory image: built for bootloader flasher or stock software flasher
* sysupgrade image: previously 'trx', designed to be flashed from within openwrt itself
additionally * uImage: a tagged linux image expected by u-boot loader (deprecated uImage) * tftp image: a remote kernel to be loaded by tftp (?) * vmlinux.bin: intermediate and plain kernel images * vmlinux.elf: dito
either get an official image from http://downloads.openwrt.org/latest/ramips/rt305x/
or build one and identify the images to flash - we take the "factory.bin"
./bin/ramips/openwrt-ramips-rt305x-dir-615-h1-squashfs-sysupgrade.bin
./bin/ramips/openwrt-ramips-rt305x-dir-615-h1-squashfs-factory.bin
connect FTDI ttl 3.3V to Dir615 (e.g. via arduino RX, TX and GND) connect ethernet between pc and dir615
$ sudo screen /dev/ttyACM0 57600
NOTE: web frontend only works with dd-wrt images the image update process needs an old HTML1.0 standard, most browsers will mess up the image before it gets there (Bad trx header)
easiest and most reliable for the dir615 it performs a hardreset via
> mtd -r erase nvram
or
> nvram erase
procedure:
configure the device to 192.168.10.1
configure the pc eth0 to 192.168.10.2
the dir615 powered, press and hold the RESET button for 30s
unpower the dir615, without releasing hold RESET for another 30s
power the dir615, STILL holding RESET for a final 30 seconds
the amber led will start blinking
on the pc open a browser to 192.168.10.1
the firmware update dialog will open, no username/password is required browse and select firmware to install
DIR615Hx-FW805B05.bin
NOTE: if the update/flashing fails, the router falls back to the last successfully installed image

connect to the bootloader, and tell it to get the images on your harddisk via its TFTP client (in case of the DIR-300 you obtain a connection via telnet on the non-default port 9000). Example:
telnet 192.168.20.81 9000
Redboot> load uboot.img
NOTE: never tested
as a single command-line:
$ echo -e "binary\nrexmt 1\ntimeout 60\ntrace\nput openwrt-xxx-x.x-xxx.bin\n" | tftp IPv4.x.y.z
step by step
$ tftp 192.168.0.1
tftp> binary
tftp> rexmt 1
tftp> timeout 60
tftp> trace
Packet tracing on.
tftp> put code.bin
"rexmt 1" will cause the tftp client to constantly retry to send the file to the given address
NOTE: never tested
$ atftp --option "mode octet" --option "timeout 60" --verbose --trace -p -l code.bin 192.168.1.1
NOTE: never tested
in case this requires to set up a ftp server on pc first (e.g. vsftp), then telnet to the dir615 and run on the dir615
$ telnet 192.168.0.1
> nvram erase
> cd /tmp
> wget [firmware.bin file]
> write [firmware.bin file] linux
> reboot
alternatively execute
$ telnet 192.168.0.1
> cd /tmp
> nvram erase # optional: bricks the router on rare types
> wget firm <firmware-url> # get the firmware from the pc ftp server
> cat /proc/meminfo | grep MemFree # show free mem
> stopservice cron # stop cron
> killall process_monitor # stop watchdog

> stopservice upnp
> stopservice pptpd
> cat /proc/meminfo | grep MemFree
> nohup mtd write firm linux &
NOTE: never tested
dd-wrt does not allow for using ssh natively, openwrt offers this possibility analog to telnet, scp the firmware file to the dir615, then proceed as in the above telnet approach
NOTE: never tested

select Image -> customized feeds -> luci2

reload the configuration
# ifup wan
# wifi
NOTE: if the target network uses the 192.168.1.0/24 subnet, you must change the default LAN IP address to a different subnet, e.g. 192.168.2.1 you can determine the assigned WAN address with the following command:
192.168.1.30
ping uplink/wan
# ping 192.168.1.1
ping client at wan/router
# ping 192.168.1.100
ping google
# ping www.google.ch
approach: NAT with routing
client(s) dir-615 inet router
eth0 lan (eth br) wan (wlan0) wifi other 192.168.10.2 }----{ 192.168.10.1 192.168.1.103 }----{ 192.168.1.1 interfaces, 255.255.255.0 255.255.255.0 255.255.255.0 255.255.255.0 wan, etc.
NAT, as above, must be up and running, then reconfigure the firewall settings disable masquerading and set the incoming traffic policy to ACCEPT
# vi /overlay/upper/etc/config/firewall
(...)
config zone
option name wan ## search zone 'wan'
list network 'wan'
list network 'wan6'
option input ACCEPT ## set to ACCEPT
option output ACCEPT
option forward REJECT
option masq 0 ## set to 0
option mtu_fix 1
config forwarding
option src wan ## set src to 'wan', and
option dest lan ## dest to 'lan'
(...)
now, the ap-router would need a route that the ip of the openwrt (dir-615) is the gateway to its subnet, i.e.
- dir-615: needs a static ip (e.g. 192.168.10.103) for its wan interface and adaptations in /overlay/upper/etc/config/network
- inet-router: needs a route to gateway for 192.168.10.0/24 being this static ip of the dir-615
then reload the configuration
# ifup wan
# wifi
restart firewall
# /etc/init.d/firewall restart
NOTE: after setup everything works BUT client subnet cannot access internet fix AP router (in this case 192.168.1.1) does not masquerade client subnet (192.168.10.0/24); if you cannot (or don't want to) modify AP router's firewall in deep, you can configure client router (192.168.10.1) in the following way
# vi /overlay/upper/etc/config/firewall
(...)
config 'zone'
option 'name' 'wan' ## in zone 'wan'
option 'input' 'ACCEPT'
option 'output' 'ACCEPT'
option 'forward' 'REJECT'
option 'mtu_fix' '1'
option masq_dest !192.168.1.0/24 ## mask the ap net
option 'masq' '1' ## enable masquerading
(...)
alternative to setups on the routers, also a local routing rule on the terminal can be configured as quickfix (or proof)

$ sudo apt-get install python python2.7 perl imagemagick subversion git gcc g++ binutils autoconf automake libtool-bin make bzip2 libncurses5-dev libreadline-dev zlib1g-dev flex bison patch texinfo tofrodos gettext pkg-config realpath libstring-crc32-perl gawk libusb-dev unzip intltool libacl1-dev libcap-dev libc6-dev libglib2.0-dev unzip wget curl zip libssl-dev
fix the problem: libssl-1.0.0 and libssl-1.1.x have changed API https://github.com/openwrt/openwrt/issues/372
--> downgrade host libssl-dev package on ubuntu/debian
fix: the image is not upgradeable via the web frontend, use tftp setup
on the linux pc install

fix
quickfix: open and comment out / delete the line that reads

fix make sure busybox -> network -> wget is installed select busybox/wget and rebuild the image

$ ./scripts/feeds update $ ./scripts/feeds install luci2 $ make menuconfig select Image -> customized feeds -> luci2 or search for it '/' entering "luci2"
