  • a factory image is one built for the bootloader flasher or stock software flasher
  • a sysupgrade image (previously named trx image) is designed to be flashed from within openwrt itself

The two have the same content, but a factory image would have extra header information or whatever the platform needs. Generally speaking, the factory image is to be used with the OEM GUI or OEM flashing utilities to convert the device to OpenWrt. After that, use the sysupgrade images.

  • a uImage is a tagged linux image expected by the u-boot loader
  • a tftp image is XXX
  • a vmlinux.bin image is XXX
  • a vmlinux.elf “image” is XXX

Flash devices can be written to, at minimum, anywhere between 100,000 and 1,000,000 times (according to the manufacturers). Keep in mind we have a normal distribution and also, that Flash never ever just stops working, but merely distinct blocks do. I.e. you won't be able to write to them any longer, but you should be able to still read them.

There are claims all over the web, that OpenWrt can only be handled by command-line. That is bullshit. As a matter of fact, there are 3 (three) WebUIs available for OpenWrt: LuCI, X-Wrt and Gargoyle
Although there is actually no reason to fear the CLI.

Also, please do note, that the X Window System is available for OpenWrt as well!

  • brcm-2.4: heavily modified Linux kernel version 2.4, wl (or wl-mimo) proprietary driver, nas authentificator, wlc control utility
  • brcm47xx: vanilla Linux kernel version 2.6/3, b43 reverse engineered FOSS driver, wpad (hostapd + wpa_supplicant), standard linux utilites (iw, iwconfig, etc.)

It is reported as still debatable which wireless driver is better for stability and performance. brcm-2.4 is still available in the latest OpenWrt stable, but has been abandoned in trunk as of Rxxxxx.

From package/madwifi/Makefile:

  MADWIFI_APPLETS += athdebug 80211debug

So first enable the “Advanced configuration options (for developers)” item, then navigate to the kmod-madwifi submenu and tick “Enable compilation of debugging features” on or add/replace “CONFIG_DEVEL=y” plus “CONFIG_MADWIFI_DEBUG=y” manually in .config
