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. 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.
