D-Link DIR-320
|
||||
==============
|
||||
|
||||
The D-Link DIR-320 wireless router has
|
||||
|
||||
* BCM5354 SoC;
|
||||
* 32 MiB SDRAM;
|
||||
* 4 MiB NOR type Flash Memory;
|
||||
* RS232 serial interface (LV-TTL levels on board!);
|
||||
* 1xUSB interface;
|
||||
* 4 + 1 ethernet interfaces;
|
||||
* 802.11b/g (WiFi) interface;
|
||||
* JTAG interface;
|
||||
* 5 LEDs;
|
||||
* 2 buttons.
|
||||
|
||||
The router uses CFE as firmware.
|
||||
|
||||
Running barebox
|
||||
---------------
|
||||
|
||||
Barebox can be started from CFE using tftp.
|
||||
You must setup tftp-server on host 192.168.0.1.
|
||||
Put your barebox.bin to tftp-server directory
|
||||
(usual /tftpboot or /srv/tftp).
|
||||
Connect your DIR-320 to your tftp-server network via
|
||||
one of four <LAN> sockets.
|
||||
|
||||
Next, setup network on DIR-320 and run barebox.bin, e.g.::
|
||||
|
||||
CFE> ifconfig eth0 -addr=192.168.0.99
|
||||
CFE> boot -tftp -addr=a0800000 -raw 192.168.0.1:barebox.bin

Ritmix RZX-50
|
||||
=============
|
||||
|
||||

|
||||
|
||||

|
||||
|
||||
* Ingenic JZ4755 SoC;
|
||||
* 64 MiB SDRAM;
|

||||
The game console uses U-Boot 1.1.6 as bootloader.
|
||||
|
||||
Running barebox
|
||||
---------------
|
||||
|
||||
1. Connect to the game console's UART
|
||||
(see. http://a320.emulate.su/2012/01/19/uart-na-ritmix-rzx-50/);
|
||||
|
||||
2. Unblock U-Boot console
|
||||
(see. http://a320.emulate.su/2012/01/25/rzx-50-dostup-k-konsoli-u-boot/);
|
||||
Please note that U-Boot's Zmodem support does not work;
|
||||
|
||||
3. Boot Ritmix linux and login;
|
||||
|
||||
4. Build barebox and upload ``barebox.bin`` via Zmodem to the board:
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
# cd /tmp
|
||||
# rz
|
||||
|
||||
..
|
||||
|
||||
5. Write barebox to onboard flash:
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
# dd if=barebox.bin of=/dev/mmcblk0 seek=1048576 bs=1 count=262144
|
||||
|
||||
..
|
||||
|
||||
6. Reboot RZX-50, next in U-Boot console start barebox:
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
CETUS # msc read 0xa0800000 0x100000 0x40000; g a0800000

TP-LINK MR3020
|
||||
==============
|
||||
|
||||
The TP-LINK MR3020 wireless router has
|
||||
|
||||
* Atheros ar9331 SoC;
|
||||
* 32 MiB SDRAM;
|
||||
* 4 MiB NOR type SPI Flash Memory;
|
||||
* RS232 serial interface (LV-TTL levels on board!);
|
||||
* 1 USB interface;
|
||||
* 1 Ethernet interfaces;
|
||||
* 802.11b/g/n (WiFi) interface;
|
||||
* LEDs & buttons.
|
||||
|
||||
The router uses U-Boot 1.1.4 as firmware.
|
||||
|
||||
Running barebox
|
||||
---------------
|
||||
|
||||
Barebox can be started from U-Boot using tftp.
|
||||
But you have to encode barebox image in a very special way.
|
||||
|
||||
First obtain ``lzma`` and ``mktplinkfw`` utilities.
|
||||
|
||||
The ``lzma`` utility can be obtained in Debian/Ubuntu
|
||||
distro by installing lzma package.
|
||||
|
||||
The ``mktplinkfw`` utility can be obtained from openwrt, e.g.::
|
||||
|
||||
$ OWRTPREF=https://raw.githubusercontent.com/mirrors/openwrt/master
|
||||
$ curl -OL $OWRTPREF/tools/firmware-utils/src/mktplinkfw.c \
|
||||
-OL $OWRTPREF/tools/firmware-utils/src/md5.c \
|
||||
-OL $OWRTPREF/tools/firmware-utils/src/md5.h
|
||||
$ cc -o mktplinkfw mktplinkfw.c md5.c
|
||||
|
||||
To convert your barebox.bin to U-Boot-loadable image (``6F01A8C0.img``)
|
||||
use this command sequence::
|
||||
|
||||
$ lzma -c -k barebox.bin > barebox.lzma
|
||||
$ ./FW/mktplinkfw -c -H 0x07200103 -W 1 -N TL-WR720N-v3 \
|
||||
-s -F 4Mlzma -k barebox.lzma -o 6F01A8C0.img
|
||||
|
||||
You must setup tftp-server on host 192.168.0.1.
|
||||
Put your ``6F01A8C0.img`` to tftp-server directory
|
||||
(usual ``/tftpboot`` or ``/srv/tftp``).
|
||||
|
||||
Connect your board to your tftp-server network via Ethernet.
|
||||
|
||||
Next, setup network on MR3020 and run ``6F01A8C0.img``, e.g.::
|
||||
|
||||
hornet> set ipaddr 192.168.0.2
|
||||
hornet> set serverip 192.168.0.1
|
||||
hornet> tftpboot 0x81000000 6F01A8C0.img
|
||||
hornet> bootm 0x81000000
