Method 3: NFS-mounted Development
(1)
The U-Boot ethernet driver is not supported in the preliminary releases, so you have to make the
following changes to the first partition – the first partition is usually named “boot”, and contains
the files “MLO” and “u-boot.img”.
Copy the zImage and z3*.dtb files to
cp targetNFS/boot/zImage /media/z3/boot/.
cp targetNFS/boot/z3*.dtb /media/z3/boot/.
(2)
Edit the uEnv.txt for NFS booting:
gedit board/u-boot*/uEnv-mmc-boot-no-tftp-rootfs-nfs.txt
(3)
Change the following values to match your NFS server IP address, and NFS path:
serverip=
192.168.0.6
rootpath=
/home/z3/z3-am57xx/targetNFS
(4)
Copy the changed file to uEnv.txt on the first partition of the SD card:
cp board/u-boot*/uEnv-mmc-boot-no-tftp-rootfs-nfs.txt /media/z3/boot/uEnv.txt
(5)
Umount the first partition of the SD card
umount /media/z3/boot
umount /media/z3/rootfs
(6)
Enable NFS on the Linux PC. The target will mount the root file system using NFS.
