PowerCloud Systems CR3000

Originally a cloud managed router the CR3000 is now only usable with OpenWrt (since the cloud service has gone away). It's a basic AR934x fast either 5-port switch with one port acting as a separate WAN interface with 2.4 GHz wireless.

-→ Install OpenWrt (generic explanation)

→ generic.flashing.tftp

→ installation

One boots a ramdisk image and then does a normal OpenWrt sysupgrade (generic.sysupgrade)

If one holds the WPS button and then (with button pressed) powers on the device (holding WPS button for 5-7 seconds) the device will attempt to download a ramdisk image named ap.bin from a tftp server (but only using the WAN port) at 192.168.1.10. Note that for 17.xx or 18.xx using the snapshot below will require the use of sysupgrade -F. Also note that some devices will attempt to load from 192.168.1.17 and that if the u-boot environment has been corrupted the ramdisk image will need to be named vmlinux.uImage.

→ Flashing from stock firmware requires Generic Flashing over the Serial Port

The correct commands for this device are:

setenv ipaddr 192.168.1.1
setenv serverip 192.168.1.234
tftpboot 0x80060000 firm.bin
erase 0x9f050000 +$filesize
cp.b $fileaddr 0x9f050000 $filesize
bootm 0x9f050000

There is no 'easy installation' from the OEM firmware for this device. Serial access in order to flash using U-boot is required.

→ generic.sysupgrade

→ generic.debrick

→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.

The default network configuration is:

This device has the CPU port on Port 0, so ports 1 - 4 are the ports labelled on the unit.

The wan port is not a switch port it is a separate interface.

How to connect to the Serial Port of this specific device:

Need to solder on a header. (see below)

: Insert photo of PCB with markings for serial port

Pin 1 is marked with an arrow and is partly covered by the wireless antenna pigtail above.

Vcc is 3.3V NOT 5V (so a PL2023 or FTDI 3.3V cable is appropriate).

: Needs to be populated by someone with a stock image

None at this time.
