DART-MX8M - Debian Setup TFTP/NFS
1 Running Debian rootfs on Variscite board using TFTP & NFS
1.1 Host
Make sure you installed NFS server:
$ sudo apt-get install nfs-kernel-server $ cd ~/var_mx8m_dart_debian $ mkdir -p ~/rootfs_debian_nfs $ cd ~/rootfs_debian_nfs $ sudo tar xvf ~/var_mx8m_dart_debian/output/rootfs.tar.gz -C .
$ sudo gedit /etc/exports
Add the following line (change <uname> to the name of user):
/home/<uname>/rootfs_debian_nfs *(rw,sync,no_root_squash,no_all_squash,no_subtree_check)
exit & save
$ sudo /etc/init.d/nfs-kernel-server restart
Make sure you installed TFTP server:
$ sudo apt-get install xinetd tftpd tftp
Verify the following:
$ ls /usr/sbin/in.tftpd $ sudo gedit /etc/xinetd.d/tftp service tftp { protocol = udp port = 69 socket_type = dgram wait = yes user = nobody server = /usr/sbin/in.tftpd server_args = /tftpboot disable = no }
and run:
$ sudo mkdir /tftpboot $ sudo chmod -R 777 /tftpboot $ sudo /etc/init.d/xinetd restart $ cd ~/var_mx8m_dart_debian
$ sudo cp tmp/deploy/images/imx8m-var-dart/zImage /tftpboot $ for f in tmp/deploy/images/imx8m-var-dart/*.dtb; do if [[ -L $f ]] && [[ $f != *imx8m-var-dart.dtb ]]; then sudo cp $f /tftpboot; fi done $ sudo rename 's/zImage-//' /tftpboot/zImage-*.dtb
1.2 Target
Make sure you have a serial connection to the target.
Reset and hold the space bar. This will bring you to U-Boot command line.
=> setenv serverip 192.168.1.188 (change 192.168.1.188 to server IP based on your network configuration) => setenv nfsroot /home/<uname>/rootfs_debian_nfs (change <uname> to the name of user) => setenv bootcmd run netboot => saveenv
You are all set. Connect Ethernet cable, power cycle the DART-MX8M and it should boot over NFS.
