This page is using the default release RELEASE_BUSTER_V1.0_DART-MX8M-MINI.

DART-MX8M-MINI - Debian Setup TFTP/NFS
Running Debian rootfs on Variscite board using TFTP & NFS
On the Host
Prepare the rootfs folder:
$ cd ~/var_mx8mm_dart_debian_buster $ mkdir -p ~/rootfs_debian_nfs $ cd ~/rootfs_debian_nfs $ sudo tar xvf ~/var_mx8mm_dart_debian_buster/output/rootfs.tar.gz -C .
Make sure the NFS server is installed:
$ sudo apt-get install nfs-kernel-server
Edit /etc/exports. E.g.
$ sudo gedit /etc/exports
...and add the following line to it (replace <uname> with the actual username):
/home/<uname>/rootfs_debian_nfs *(rw,sync,no_root_squash,no_all_squash,no_subtree_check)
Restart the NFS server:
$ sudo /etc/init.d/nfs-kernel-server restart
Make sure the TFTP server is installed:
$ 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_mx8mm_dart_debian_buster
$ sudo cp -a ~/rootfs_debian_nfs/boot/*.dtb /tftpboot $ sudo cp ~/rootfs_debian_nfs/boot/Image.gz /tftpboot
The default kernel configuration should be modified to compile Ethernet driver into kernel image instead compiling it as a loadable module.
Follow our kernel compilation guide Build kernel from source code
Run "make menuconfig", go to "Device Drivers → Network device support → Ethernet driver support → Freescale devices → FEC ethernet controller" and press y.
Follow this same process to also change the following drivers to built-in:
CONFIG_AT803X_PHY=y
CONFIG_ADIN_PHY=y
On the 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-MINI and it should boot over NFS.
