How to: Upgrade u-boot and loader on SRX Branch Devices using TFTP method.

Symptoms

Some older hardware may require a u-boot and loader update. For upgrades with JUNOS 10.0R1 is later, follow the Shell command method outlined in KB16317 - How to: Upgrade u-boot and loader on SRX Branch Devices using TFTP method [juniper.net] .

For 9.6 or earlier releases or if any issue is encountered with the Shell command method, the procedure to upgrade by using the TFTP method can be used.

This article is applicable to the following devices:

  • SRX 100

  • SRX 110

  • SRX 210

  • SRX 220

  • SRX 240

  • SRX 550

  • SRX 650

Upgrading u-boot and loader requires console access and an external TFTP server that is reachable via the ge-0/0/0 interface. In this example, assume the following parameters:

  1. TFTP server is 172.19.50.129 .
  2. Device IP is 172.19.46.94/24 .
  3. Default Gateway for device is 172.19.46.1 .
  4. Files for u-boot ( u-boot-crc.bin ) and loader ( loader_crc ) are already uploaded to the root directory of the TFTP server.

    Note : filenames may change between image versions.

Solution


The procedure to upgrade u-boot and loader is as follows:

You can also refer to KB14175 - How to: Upgrade u-boot and loader on SRX Branch Devices from Shell [juniper.net] .

Also - The JUNOS 10.0 image contains the latest boot loader binaries in the following path: /boot/uboot, /boot/loader.

  1. Upgrade u-boot by rebooting the device. Note build time for old u-boot on console window.
