Version Date DIVELK version Notes
1.0.0 November 2018 XELK 3.0.1 First release

Introduction

This configuration is very helpful during the software development (both for kernel and applications). The kernel image is downloaded via TFTP while the root file system is remotely mounted via NFS from the host. It is assumed that the development host:

  • is connected with the target host board through an Ethernet LAN
  • exports the directory containing the root file system for the target through the NFS server
  • runs a TFTP server.
  • has a proper subnet IP address

net_nfs configuration

XELK 3.0.0 Virtual Machine is properly configured for the TFTP and NFS debug.

In any case, some variables has to be configured on the target and the VM itself has to be configured for respect to the network environment.

Host (Virtual Machine) configuration

The XELK Virtual Machine has the tftp and nfs services already running. Optionally, their configuration has to be changed according to the network configuration where the target is connected to.

Check and properly configure the items the following chapters: network adapter, nfs server

network adapter

The network adpater should be configured in bridge mode in order to allow thge target to get the files from the VM

then check or re-configure the Host IP address

dvdk@vagrant-ubuntu-trusty-64:~$ 

nfs server

The NFS server should exports the correct file system directory (in our example)

dvdk@vagrant-ubuntu-trusty-64:~$ cat /etc/exports 
/home/dvdk/axel/rfs 192.168.0.0/255.255.255.0(rw,async,no_root_squash,no_subtree_check)
dvdk@vagrant-ubuntu-trusty-64:~$ 

otherwise, change its configuration and then restart the nfs server:

dvdk@vagrant-ubuntu-trusty-64:~$ sudo /etc/init.d/nfs-kernel-server restart

dvdk@vagrant-ubuntu-trusty-64:~$ 

Target configuration

The IP address for server and target should be configured: an example (for a network subnet 192.168.0.x)

=> setenv serverip 192.168.0.125
=> setenv ipaddr 192.168.0.95
  • serverip is the IP address of the host machine running the tftp/nfs server
  • ipaddr is the IP address of the target

The kernel and device tree files has to be selected

=> setenv bootfile /tftpboot/axel/xelk-3.0.4_uImage
=> setenv fdtfile /tftpboot/axel/xelk-3.0.4_imx6dl-sbcx-cb0048.dtb

finally, the root file system directory on the Virtual Machine should be configured for let the kernel to find the INIT

=> setenv rootpath /home/dvdk/axel/rfs/xelk-3.0.1


To run this configuration just issue the net_nfs command which firstly download the kernel and device tree using the tftp protocol

=> run net_nfs
