In order to download a remote ramdisk and mount it localy on the board you have to set a variable that will lead U-Boot to it. The command used to download a kernel image and place it in a specific the paths used in the following commands start from the root directory of Out are fetched from a root directory already configured in TFTPSERVER configįile. TFTP (Trivial File Transfer Protocol) allows to exchange files across the network,Ī TFTPSERVER that is running on a PC(host) handles all TFTP request. Note : The values given to these variables should be set to whatever your system and network, especially for ip and ethernet addresses which should match your network parameters.īefore we hit the command setting let's have a look at how a TFTP server works.
You have to set up some variables like network ones (Ethenet address, IP address.) and bootdelay. Copy the ramdisk image (ramdisk-rmk7) to the tftp server default directory.Copy the linux kernel image (uImage) to the tftp server defaut directory.
