| Note these instructions are all based on the mightyOhm articles. This is a little bit different because I wanted to get alsa sound working (instead of dsp) so that I could overlay effects | |
| and background sound simultaneously. | |
| What to do | |
| ========== | |
| install mightyohm trx | |
| setup network and wireless | |
| vi /etc/opkg.conf | |
| src/gz snapshots http://192.168.24.104/mightyohm | |
| opkg update | |
| opkg install kmod-usb-ohci kmod-alsa alsa-lib | |
| bplay | |
| ===== | |
| # Note you may need to also change "dest root /" to "dest root /jffs" to use the overlay | |
| vi /etc/opkg.conf | |
| src/gz snapshots http://192.168.24.104/packages | |
| Mpd | |
| === | |
| vi /etc/opkg.conf | |
| src/gz snapshots http://mightyohm.com/files/kamikaze-2.4/packages/mipsel | |
| opkg update | |
| install mpd mpc | |
| reboot | |
| vi /usr/share/alsa/alsa.conf | |
| change | |
| defaults.pcm.ipc_gid audio | |
| to | |
| defaults.pcm.ipc_gid root | |
| blind flashing: | |
| =============== | |
| configure local machine lan hardware to 192.168.1.185 manual address (so you are on the .1 network) | |
| connect network cable (not crossover) from local machine to LAN1 port | |
| if your current network (wireless) is on a .1 network you can (a) change it (b) turn off wireless while you do stuff | |
| power off router | |
| hold down Restore button | |
| power on router | |
| LED should start flashing once per second, release Restore button | |
| ping 192.168.1.1 | |
| cd < whereever the trx file is, maybe kamikaze/bin > | |
| tftp | |
| trace | |
| timeout 1 | |
| mode binary | |
| connect 192.168.1.1 | |
| put openwrt-brcm-2.4-squashfs.trx | |
| wait 10 minutes, don't touch anything. | |
| reboot the router (unplug, wait a couple seconds, plug it back in) | |
| ping 192.168.1.1 (wait until it starts responding) | |
| telnet 192.168.1.1 | |
| network setup | |
| ============= | |
| vi /etc/config/wireless | |
| config wifi-device wl0 | |
| option type broadcom | |
| option channel 6 # the channel your wireless network is on | |
| config wifi-iface | |
| option device wl0 | |
| option network lan | |
| option mode sta | |
| option ssid MyNetwork # the SSID of your network | |
| option encryption psk # the encryption mode of your network (or wep) | |
| option key XXXXXXXXXX # add this line with your preshared key in place of X...X | |
| vi /etc/config/network | |
| # Only update this section: | |
| #### LAN configuration | |
| config interface lan | |
| option type bridge | |
| option ifname "eth0.0" | |
| option proto dhcp | |
| #### You could optionally give a manual address still, but make sure it is on your wireless subnet | |
| #option ipaddr 192.168.1.1 | |
| #option netmask 255.255.255.0 | |
| #### WAN configuration | |
| config interface wan | |
| option type bridge | |
| option ifname "eth0.1" | |
| option proto static | |
| option ipaddr 192.168.1.1 | |
| option netmask 255.255.255.0 | |
| vi /etc/config/firewall | |
| #### Update the wan zone so it looks like the lan zone | |
| config zone | |
| option name wan | |
| option input ACCEPT | |
| option output ACCEPT | |
| option forward REJECT | |
| /etc/init.d/network restart | |
| #### This will disconnect you. Change the network cable to be plugged into the WAN port and | |
| #### you can again telnet to 192.168.1.1. You can also telnet to your wireless network by | |
| #### finding out which dhcp address it picked up (check your normal wireless router for clients) | |

| # How to add a package (https://forum.openwrt.org/viewtopic.php?id=16040) | |
| (1) find the package you are looking for and check it out/copy into $base/package/<package name> | |
| (2) Fixup the makefile | |
| (3) Compile just that package and rebuild the index! | |
| make package/<name>/{clean,compile} package/index | |
| (4) Select the package (M) | |
| make menuconfig | |
| (5) Rebuild the index again | |
| make package/index | |
| (6) Copy those packages to your webserver so opkg can see it | |
