In this article, we’ll be using the SolarWinds TFTP Server ( download here) which is pretty easy to use and it lets you transfer files with reliability and at a fast speed over a network. A quick workaround would be to use a TFTP Server, it’s simple and easy to set up. ![]() However, it has been removed from Windows 10 in the v1803 update due to which alternate resolutions are required. We all know the Windows Homegroup that lets you share files over a network without any great hurdle. The protocol is very basic and doesn’t provide much security to the files that are being transferred. TFTP, also known as Trivial File Transfer Protocol, is an internet software utility that you can use to send or receive a file from a remote system. MAC(0002F70066E3,0x1)/IPv4()/juno/juno.A TFTP Server is basically used to transfer files between systems that are connected over a network. LoaderType: Linux kernel with FDT support Arguments: console=ttyAMA0,115200 earlyprintk=pl011,0x7ff80000 root=/dev/sda2 rootwait verbose debug Next update the FDT entry for the TFTP boot entry: Add Boot Device Entryįile path of the FDT blob : juno/juno.dtbįinally, return to the main menu and select the new `TFTP boot example' option: Add Boot Device Entry Get the IP address from DHCP: yįile path of the EFI Application or the kernel : ImageĪrguments to pass to the binary: console=ttyAMA0,115200 earlyprintk=pl011,0x7ff80000 root=/dev/sda2 rootwait verbose debugĭescription for this new Entry: TFTP boot example Note that in this example the filesystem is on a USB stick ( `/dev/sda2'). TFTP on MAC Address: 00:02:F7:00:66:E3Įnter each setting as shown below, where `' is the IP address of your host PC in the form `'. Select `TFTP on MAC Address': Firmware Volume (0 MB) Select `Add Boot Device Entry': Add Boot Device Entry Arguments: dtb=board.dtb initrd=ramdisk.img console=ttyAMA0,115200 androidboot.hardware=juno systemd.log_target=null rootwait root=/dev/sda2 sky2.mac_address=0x04 We've left this information here for legacy support.įirst select the `Boot Manager' option: Linaro image in NOR Flash This section is not applicable from Linaro Release 16.02 onwards the EDK-II based UEFI provided as part of the deliverables does not support TFTP boot. 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.
