You can set up a shared connection using these commands: sudo nmcli connection edit type ethernet nmcli> set thod shared nmcli> save nmcli> quitĬheck the shared ip_address. Alternatively, Network-manager offers a built-in interactive console to achieve the same.
#U BOOT TFTPBOOT PC#
#U BOOT TFTPBOOT ARCHIVE#
Locate the large Linux filesystem archive file, then execute the following command on the Ubuntu host PC (with the NFS server already started) to extract the RZBoard file system into the NFS server folder: sudo tar xfj /2 -C /nfs/rzv2l ls /nfs/rzv2l/ bin dev home lib64 mnt run sys usr boot etc lib media proc sbin tmp var Note: If the above command did not show the expected result, please restart the Ubuntu PC, and try it again. sudo exportfs -a showmount -e localhost Export list for localhost: /nfs/rzv2l * If the same result is shown, the NFS server is successfully started.
Refresh the NFS server, then confirm the NFS server is successfully started by executing the following command. # Example for NFSv2 and NFSv3: # /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check) # Example for NFSv4: # /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check) # /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check) # /nfs/rzv2l *(rw,no_subtree_check,sync,no_root_squash) nfs/rzv2l *(rw,no_subtree_check,sync,no_root_squash) sudo nano /etc/exports cat /etc/exports # /etc/exports: the access control list for filesystems which may be exported # to NFS clients. Modify the NFS server configuration, by adding the following line at end of the /etc/exports file: Start the NFS server and create a directory for RZBoards NFS service: sudo /etc/init.d/nfs-kernel-server start sudo mkdir /nfs/rzv2l -p sudo cp /Image /tftpboot sudo cp /rzboard.dtb /tftpboot $ ls -l /tftpboot/ total 21632 -rw-rw-r- 1 bn bn 12 Jan 27 14:19 hello.txt -rw-r-r- 1 root root 22168064 Jan 27 14:58 Image -rw-r-r- 1 root root 44941 Jan 27 15:05 rzboard.dtb The files, after building yocto image according to the instructions from meta-rzboard/README.md, will be in this folder: "//yocto_rzboard/build/tmp/deploy/images/rzboard". Locate RZBoards Linux kernel Image file and devicetree rzboard.dtb file and copy these into the TFTP server folder at /tftpboot. Note: If the above command did not show the expected result, then you should restart the Ubuntu hostPC, and try this again. If no error message is displayed, the TFTP server is successfully started. Start the TFTP server, then confirm it has started using the commands below: sudo systemctl enable tftpd-hpa sudo systemctl restart tftpd-hpa sudo chmod 777 /tftpboot sudo echo “Hello” > /tftpboot/hello.txt sudo tftp localhost > get hello.txt Set up the TFTP server configuration file.Create /etc/default/tftpd-hpa file, containing the following configuration: TFTP_USERNAME="tftp" TFTP_DIRECTORY="/tftpboot" TFTP_ADDRESS=":69" TFTP_OPTIONS="-secure" $ sudo nano /etc/default/tftpd-hpa
#U BOOT TFTPBOOT INSTALL#
Download it and unzip it.įollowing are the steps to configure a network boot for RzBoard on the host system.Įnter the following to install the TFTP server, as well as the NFS server utilities: sudo apt-get update sudo apt-get install tftp tftpd-hpa nfs-common nfs-kernel-server cuĬreate a directory for the TFTP server: sudo mkdir /tftpboot We will use these pre-built images from RZBoard_EdgeImpulse_Netboot. To set up network boot for RzBord, we need to configure the Ubuntu host system and also configure Rzboard. Linux Host setup: Network boot from an NFS Root Filesystem for RZBoard V2L The RED cable connector should not be connected. The Same for TXD which is RzBoard's Transmitter to the other device. RXD is RzBoard's Receiver, which means the transmitting cable to Rzboard goes there.
