Initial installation can be done from the stock firmware web interface, or from the CFE web interface. Unfortunately installation via TFTP seems to have been disabled for this device.
One important note is that the CPVA642 models have a dual image setup. That means if an image fails to boot, the system will fall back to the other image installed, for the stock firmware. We don't actually want this, because it means that if you flash via the CFE web interface when there is already a good image, the image will not be written to the start of flash but to a point 4MB from the start (i.e. as if there were two 4MB images). This confuses OpenWrt.
That means if you have a successfully flash image and you want to flash via the CFE web interface, you need to erase everthing except the bootloader first.

Serial port is marked in the picture: on the right of the switch chip BCM5325 find two soldered holes enclosed in squares. The left one, above R707 is Receive data, the right above R706 is Transmit. Level 3V. Gnd is the hole near c809, +3Vcc is the hole near C313
How to connect to JTAG interface, and how to reflash the device with JTAG tools
See port.jtag for more JTAG details.
If you forgot your password, broken one of the startup scripts, firewalled yourself or corrupted the JFFS2 partition, you can get back in by using OpenWrt's failsafe mode.
NOTE: The root file system in failsafe mode is the SquashFS partition mounted in readonly mode. To switch to the normal writable root file system run mount_root and make any changes. Run mount_root now.
uci get network.lan.ipaddr
mtd -r erase rootfs_data If you are done with failsafe mode power cycle the router and boot in normal mode.
The CPA has two buttons. They are Reset and Wireless Setup. The buttons can be used with hotplug events. E. g. [#wifitoggle WiFi toggle].
