howto_865x

Warning! This is beta-howto of midge rtl865x brach. Patches, bug discussion are welcome at Midge Forum

• CPU: Realtek RTL8650B
• 2 Mb NOR Flash
• 16 Mb SDRAM
• 5 Ethernet
• 1 USB 1.1 (on PCB)
• 2 UART (1 port on PCB)

RTL865xb has two serial/console port. PCB of Edimax BR-6214 there is a 4 pin connector marked JP1.

1-o o o o-4

1 - +3.3V
2 - Rx
3 - Gnd
4 - Tx

Port setup: 38400 8N1

More hardware hacks

Download latest svn:
svn co http://midge.vlad.org.ua/svn/trunk/openwrt-midge/
after downloading run ./make-rtl865xb in openwrt-midge directory

To upload the firmware under Edimax-BR6214K you need DHCP and TFTP servers.

To install servers under Debian just type:
apt-get install tftpd dhcp3-server

• Make sure that UDP 67,69 ports are opened

• Put your firmware to /src/tftp

• Edit new host configuration in /etc/dhcp3/dhcpd.conf

host br6214k 
{
        hardware ethernet 00:0e:2e:fe:73:76;  # MAC-address of device
        fixed-address 192.168.0.2;
        next-server 192.168.0.100; # TFTP server 
        filename "br6214k.bix"; # Firmware name
}

• Connect console cable to PC
• Start terminal program (minicom, HyperTerminal, etc)
• Setup 38400 8N1, no hardware handshaking
• Turn on power to the router
• On screen you will see prompt
• Quickly press ‘r’
