Hi All,
I am trying to boot the s32g274ardb2 board through "nfsboot" option from u-boot. I see the kernel & dtb files are loaded through tftp and booted properly until kernel stops at the time of NFS mount. Have exported the nfs folder by running "sudo systemctl restart nfs-kernel-server" and rootfs (fsl-image-auto-s32g274ardb2.tar.gz) image is kept at the exported location /tftpboot/rfs. Find below the nfs boot args and the kernel log where it stops.
Bootargs
nfsboot=echo Booting from net using tftp and nfs...; run nfsbootargs;run loadtftpimage; run loadtftpfdt;${boot_mtd} ${loadaddr} - ${fdt_addr};
nfsbootargs=setenv bootargs console=${console},${baudrate} root=/dev/nfs rw ip=${ipaddr}:${serverip}::${netmask}::eth0:off nfsroot=${serverip}:/tftpboot/rfs,nolock,v3,tcp earlycon nohz=off coherent_pool=64M
Kernel log where it stops

In kernel config file all NFS related options are selected.
What could be the reason and how to resolve this NFS mounting issue?
With regards,
