To revert back to the default boot behaviour: VExpress64# set bootcmd "$origbootcmd" UEFI TFTP the Juno will boot via TFTP on every power up. Reboot the Juno it should now boot via TFTP. Next modify U-Boot's boot command to boot via TFTP: VExpress64# set origbootcmd "$bootcmd" Save your host PC's IP address to the `serverip' environment variable: VExpress64# set serverip Power up the Juno board and interrupt U-Boot's default boot selection: The default boot selection will start in 3 seconds Device tree blob: `/tftpboot/juno/juno.dtb'.This example expects the paths to be as follows: Get the IP address of your host PC via `ifconfig', then from another system: $ tftp Īfter confirming that the TFTP server is working correctly, copy your kernel image, device tree blob, and ramdisk (where appropriate) to `/tftpboot/'. Test the server by creating a simple `test' file in `/tftpboot/': $ cd /tftpboot/ Restart the `xinetd' service: $ sudo service xinetd restart ![]() Install the following packages on your host PC: $ sudo apt-get update & sudo apt-get install xinetd tftpd tftpĬreate file `/etc/xinetd.d/tftp' with the following contents: service tftpĬreate directory `/tftpboot/' (this matches the `server-args' above) and set its permissions: $ sudo mkdir /tftpboot/ See this page for instructions on how to network mount a userspace filesystem using U-Boot. If using Juno, ensure you are using the front ethernet port. ![]() Technical Support - Cisco Systems provides platform-specific information on how to troubleshoot.This tutorial assumes your host PC is running Ubuntu 14.04.1 LTS or later and is on the same local network as your development platform for simplicity's sake we assume a DHCP server is available on the network, too. The TAC Case Collection Tool ( registered customers only) provides interactive troubleshooting simply choose the product area (LAN Switching, Router and IOS Architecture, and so on) for your device. There are a variety of problems which may occur when you use TFTP for maintenance. Check the size of your image and verify that the TFTP server you have in mind supports large transfers, if needed. Support for transfers over 16 MB in size-Some Cisco devices require images that are over 16 MB in size. Security features-Security features may be an important consideration based on the location of the TFTP server in your network. When you choose between packages, consider these features: For more information on this, refer to Cisco TFTP Server. Note: The Microsoft Windows-based TFTP server previously provided by Cisco Systems has been discontinued and is no longer supported by Cisco Systems. Additionally, there are excellent TFTP server packages offered for sale. There are many freeware TFTP servers on the internet.
