Kria 260 boards

KV260, rootfs on NFS

1. Create project using proper BSP file
2. Export hardware using proper vivado project (Pay attention on units enabled for PSU (should match the ones defined in BSP), as in case it differs - build will fail)
3. Chose ROTTFS on NFS
4. Disable nfs-utils in rootfs config
5. Enable nfs-server support in kernel config
6. tbd
7. build project
8. copy images to tftpboot directory
9. create shared directory and unpack rootfs there using : tar -xvf rootfs.tar.gz -C --same-owner
10. open /etc/fstab in unpacked rootfs, comment out line : "LABEL=boot /boot vfat defaults 0 2" as it causes boot stuck
11. tbd

Example u-boot cli :

• setenv bootargs "ip=192.168.0.111:192.168.0.100 root=/dev/nfs rootfstype=nfs nfsroot=192.168.0.100:/mnt/nfs_share/k26/,nfsvers=3,tcp rw";
• setenv serverip 192.168.0.100
• setenv ipaddr 192.168.0.111

U-boot env examples for rootfs on nfs :

setenv bootargs "ip=192.168.0.111:192.168.0.100 root=/dev/nfs rootfstype=nfs nfsroot=192.168.0.100:/mnt/nfs_share/k26/,nfsvers=3,tcp rw"
setenv serverip 192.168.0.100
setenv ipaddr 192.168.0.111

# Or

setenv bootargs "ip=dhcp root=/dev/nfs rootfstype=nfs nfsroot=10.42.0.1:/mnt/nfs_share/k26/,nfsvers=3,tcp rw"
setenv serverip 10.42.0.1
