Cisco vEdge 1000

Cisco/Viptela vEdge 1000|

The Cisco vEdge 1000 is a small form factor SD-WAN appliance previously sold as Viptela vEgde 1000. It is based on the Niagara 821 board by the ODM Interface Masters.

WIP

Basic plattform support is available in the main branch since https://github.com/openwrt/openwrt/commit/6bf0e7649400f5c25828061d14dd5aa76bfc1211.

Currently there is a private fully-featured OpenWrt port pending kernel patch upstreaming before they are submitted to OpenWrt.

Alternative 1: Boot installation from inside OEM OS (USB drive, SD card, SSH, HTTP(S))

Note: OEM OS only supports mounting vfat partitions automatically

  • Copy ./bin/targets/octeon/generic/openwrt-octeon-generic-cisco_vedge1000-initramfs-kernel.bin to /boot/openwrt-install.bin
  • touch /boot/in_prod to unlock u-boot if required
  • Reboot vEdge
  • Press ctrl-x to enter u-boot
  • Run the following commands:
    • usb start
    • ext2load usb 0:1 $loadaddr openwrt-install.bin
    • bootoctlinux $loadaddr endbootargs
  • Skip to the Prepare the disk step

Alternative 2: Boot installation from unlocked u-boot via TFTP

  • If you are not in the u-boot prompt, reboot the device and press Ctrl-x to enter u-boot
    • If this does not work, see the “Unlock u-boot” section.
  • Connect the vEdge 1000 via the management Ethernet port to a network with DHCP available
  • Run the following commands, replace the IP with your TFTP server:
    • setenv ethact octmgmt0; dhcp; setenv serverip 10.1.2.3
    • setenv ethact octmgmt0; tftpboot $loadaddr $serverip:/openwrt-octeon-generic-cisco_vedge1000-initramfs-kernel.bin
    • bootoctlinux $loadaddr endbootargs

Example tftp server command: sudo /usr/sbin/in.tftpd -sLv .

Prepare the disk

The vEdge 1000 has been found to have a disk ID of zero by default. This needs to be rectified in order for OpenWrt to reliably be able to find the root partition. This step only has to be done once as it is permanent unless the full disk is re-partitioned manually by the user.

  • Verify if you need to change the disk ID by running blkid -t LABEL=boot
    • You should get a single line like this: /dev/sda1: LABEL=“boot” UUID=“e74e53f8-dbfd-4b1f-8fc9-ba6528c03635” BLOCK_SIZE=“4096” TYPE=“ext2” PARTUUID=“01013160-01”
    • If you are missing the PARTUUID part, you need to follow the next instruction - otherwise you can skip ahead to the next section.
  • Generate a new disk ID by running the following commands:
    • udhcpc -i br-lan
      echo 'nameserver 1.1.1.1' > /etc/resolv.conf
      opkg update
      opkg install sfdisk
      source /lib/upgrade/platform.sh
      sfdisk --disk-id "$(platform_get_n821_disk)" 0x10"${RANDOM}"
  • Now loop back to step 1 above and verify that the boot partition has a PARTUUID property. Then continue with the installation.

Running the installation

You need to make the file openwrt-octeon-generic-cisco_vedge1000-squashfs-sysupgrade.tar available to the installation.

HTTP from Github
udhcpc -i br-lan
echo 'nameserver 8.8.8.8' > /etc/resolv.conf
cd /tmp/
wget https://github.com/sonix-network/openwrt/releases/download/[..]octeon-generic-cisco_vedge1000-squashfs-sysupgrade.tar
sysupgrade -n /tmp/*vedge1000-squashfs-sysupgrade.tar
USB drive
mount /dev/sdb1 /mnt
sysupgrade -n /mnt/openwrt-octeon-generic-cisco_vedge1000-squashfs-sysupgrade.tar
OpenSSH SCP
udhcpc -i br-lan
# On another machine: scp -O openwrt-octeon-generic-cisco_vedge1000-squashfs-sysupgrade.tar root@10.x.x.x:/tmp/
sysupgrade -n /tmp/openwrt-octeon-generic-cisco_vedge1000-squashfs-sysupgrade.tar

Done! It is recommended to power-cycle the device to ensure that e.g. the LED and USB controllers are reset to a known state.

Sync and reset fallback partitions

The vEdge 1000 has support for two U-Boot bootloaders. It is recommended to sync and force a switch to the primary partition.

In U-Boot, execute the following:

# optional: ensure USB3 ports are enabled
setenv ext_usb_setup "i2c dev 1; i2c smbwrite 6e 01 01 ff; cpld_wr 0x4 0x00"

cpld_wr 0xa 0x2
saveenv
cpld_wr 0xa 0x0
saveenv
reset
source /lib/upgrade/platform.sh
mkdir /mnt
mount "$(platform_get_n821_disk 1)" /mnt
rm /mnt/in_prod
umount /mnt
reboot

In the “Viptela vEdge-1000 Boot Console” interface select ESC to enter recovery mode and select “Reset u-boot environment”. The system will restart but fail to boot with a bunch of file system related errors. At this point press the reset button on the front panel for 10 seconds and let go. The system should now boot up correctly in the OEM software

generic.debrick

The vEdge 1000 has a 16 MiB NOR flash that is split into two 8 MiB flash banks. Only one is active at the time, allowing for a primary and secondary bootloader to be present.

Pressing, holding for more than 10 seconds, and letting go of the reset button flips the boot bank selection to the other bank. This can be verified by executing cpld_rd 0xa in u-boot. It will read either 0x0 or 0x2 depending on the bank that is currently active. You can switch the bank using e.g. cpld_wr 0xa 0x0.

This should allow you to enter a working u-boot and boot OpenWrt live image using TFTP, allowing you to install OpenWrt as usual.

Example U-Boot commands:

cpld_wr 0xa 0x2
dhcp
setenv serverip 1.2.3.4
tftpboot $loadaddr $serverip:/openwrt.bin
bootoctlinux $loadaddr coremask=f endbootargs
# Wait for OpenWrt to boot, verify that you are operating against the *broken* flash bank
hexdump -C /dev/mtdblock0 | head -n 1000
# scp the u-boot.bin you want to recover
dd if=uboot.bin of=/dev/mtdblock0 bs=1M
sync
reboot -f
# You should be booting correctly now

If you get a Permissioned denined error while writing to /dev/mtdblock0 you likely need to remove the read-only property for the bootloader partition in the device tree.

For more advanced debricking, there is a JTAG section. However, as of this writing there is no definite guide how to load a new u-boot onto a bricked flash bank. It should be possible using the flash [..] OpenOCD commands - however note that the NOR flashes uses swapped byte order so ensure you compensate for that.

The unit is shipped with two power adapters, part number FSP060-DIBAN2. A DC connector w/ the dimensions 2.1×5.5×9.5mm is suitable. The stock PSU is rated 60W but in reality anything at 30W or higher should work fine. During stress testing the vEdge 1000 has been pushed to draw 28W at worst-case but during normal loads it should be closer to 15-20W. The unit works fine with voltage levels between 6.5V up to 15.2V - higher voltages might be possible but has not been tested.

port.serial general information about the serial port, serial port cable, etc.

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

The serial interface on the front is a standard Cisco RJ45 serial port labelled as “console”. It is possible to enter u-boot by interrupting the boot process when prompted to hit ctrl-x. On newer firmwares this method is not directly accessible and will require additional work, see below.

Alternatively the USB Type-B on the front can be used to connect to the serial console.

Unlocking u-boot

Entering U-boot is achieved by pressing Ctrl-x when booting. The prompt is something like this:

The least complicated way to unlock U-boot is to create a file called in_prod on the first partition on the internal disk, however that requires rooting the OEM software on the device. A bit more complicated, but universal, way to unlock U-boot is to put the device into testbed mode by using an I2C gadget.

As part of the secure boot flow U-boot will be searching for an I2C EEPROM at address 0x75 on the JP3 header (see “12B” on the photo of the main board). If the device is found, it will compare the contents of the EEPROM with the string Viptela and if it matches, enable testbed mode. In testbed mode you have access to utilities like the U-boot console.

One straightforward way to create such a gadget is to use an Arduino microcontroller. Documented below is code and connection schematic for using an Arduino Uno controller connected via normal 0.64mm jumper wire. If you have no previous experience nor equipment to build this hardware yourself there are kits available that contain everything you need - example of such a kit is the ELEGOO UNO Basic Starter Kit

Use the following code:

include <Wire.h>
 
void setup() {
  Wire.begin(0x75);
  Wire.setClock(100 * 1000);
  Wire.onRequest(requestEvent);
  Serial.begin(9600);
  Serial.println("Cisco vEdge u-boot testbed unlock");
}

void requestEvent() {
  Wire.write("Viptela");
  Serial.println("Processing I2C read ...");
}
 
void loop() {
  delay(50);
}

A5 SDA left-most on the picture, arrow on the PCB points to this pin
A4 SCL center pin
GND GND right-most on the picture

When booting with this gadget correctly attached you should be greeted with a recovery menu that looks like this:

JTAG TRST PIN1 PIN2 GND
JTAG TDI PIN3 PIN4 GND
JTAG TDO PIN5 PIN6 GND
JTAG TMS PIN7 PIN8 GND
JTAG TCK PIN9 PIN10 GND
JTAG SRST PIN11 PIN12 Not connected
GPIO #4 PIN13 PIN14 Vcc / Vio

Note that when SRST is used the flash bank toggles every system reset, so make sure you compensate for that so you do not accidentally modify the wrong flash bank.

Example configuration for OpenOCD:

source [find interface/ftdi/olimex-arm-usb-ocd.cfg]
ftdi tdo_sample_edge falling
reset_config trst_and_srst
adapter speed 10000

Trying to up an interface fails

RTNETLINK answers: No error information

This will happen if the port is configured for SGMII and did not have a PHY inserted at boot time. Reboot the unit and it should be able to up the link.

Kernel panic - not syncing: ������

This message with broken glyphs can occur if you enable CONFIG_TARGET_INITRAMFS_COMPRESSION. Maybe the support is broken for MIPS64, or maybe it is broken for just this platform.

Crash when loading kernel after "Allocating memory for ELF segment:"

This error can happen if the initramfs image is too large. Images larger than 256 MiB seems to be unbootable.
