Hi All.
a) As a pre-requisite, on the host-machine (serverip 192.168.0.1), the nfs-export is listed fine : ajay@latitude-3480:~showmount -e localhost Export list for localhost: /srv/nfs/cubieboard2 * b) The zImage and dtb files have been generated from 4.6 kernel, as per steps at https://github.com/maronai/cubieboard/wiki/3.1.-Compiling-mainline-kernel-for-CubieBoard2-and-CubieTruck Now, when trying to boot cubieboard2 via tftp/nfs, I get a hang, all details as below : ########################################################################################################### U-Boot SPL 2017.01-2 (Jan 18 2017 - 21:30:38) DRAM: 1024 MiB CPU: 912000000Hz, AXI/AHB/APB: 3/2/2 Trying to boot from MMC1 U-Boot 2017.01-2 (Jan 18 2017 - 21:30:38 -0700) Arch Linux ARM CPU: Allwinner A20 (SUN7I) Model: Cubietech Cubieboard2 I2C: ready DRAM: 1 GiB MMC: SUNXI SD/MMC: 0 In: serial Out: serial Err: serial SCSI: SATA link 0 timeout.
