Hardware specifications:
- CPU: Freescale/NXP P2020, dual-core PowerPC @ 1 GHz
- RAM: 1 GB DDR3
- Flash: 2 MB NOR, 512 MB NAND
- Networking: 7x Gigabit Ethernet ports (via two Marvell 88E6171
switches, each attached to a different MAC)
- USB: 2x USB 2.0 ports (front panel)
- mini-PCIe slot
- RTC: Ricoh RS5C372A
- 4 buttons (via external MCU)
- 3 LEDs (via external MCU)
- LCD display (via external MCU)
Installation procedure:
1. Obtain the original MAC address table from the stock bootlog, for
example:
setting device eth0 to 00:90:7f:00:00:01
setting device eth1 to 00:90:7f:00:00:02
setting device eth2 to 00:90:7f:00:00:03
setting device eth3 to 00:90:7f:00:00:04
setting device eth4 to 00:90:7f:00:00:05
setting device eth5 to 00:90:7f:00:00:06
setting device eth6 to 00:90:7f:00:00:07
2. Open the case and move jumper JP1 from 2-3 to 1-2 to enter FAILSAFE
mode.
3. Power on the device and interrupt the boot process to access the U-Boot
shell.
4. Program the MAC base address into the EEPROM (text after '#' is a
comment):
mac ports 3
mac 2 00:90:7f:00:00:01 # first MAC address from bootlog
mac save
5. Reset the device and enter the U-Boot console again.
6. Connect a TFTP server to port 6 and boot the initramfs image:
setenv ipaddr 192.168.1.3
setenv serverip 192.168.1.2
setenv loadaddr 1000000
tftpboot $loadaddr openwrt-mpc85xx-p2020-watchguard_xtm330-initramfs-kernel.bin
bootm $loadaddr
7. (Optional) Backup all MTD partitions if you want the ability to restore
stock firmware.
8. Perform a normal sysupgrade from the initramfs environment.
9. Power off the device and move jumper JP1 back to 2-3.
10. The device will now boot OpenWrt.
Known issues:
- LCD, buttons and LEDs are controlled by an external MCU; the protocol is
currently unknown.
- The internal connection between the two Marvell switches is unused by
OpenWrt.
- The stock firmware uses an empty U-Boot environment; saving variables
modifies the environment and prevents a normal boot. FAILSAFE U-Boot
remains functional.
- WatchGuard configuration is encrypted; DSA MAC addresses are stored in
this configuration.
- Failsafe Ethernet works on port1.
