Write down the size of loaded file - you will need it later for counting number of sectors. In u-boot console use fatload mmc 0:1 0xC0000000 u-boot.s32 command. We need to copy u-boot.s32 from SD Card to RAM (use RAM address 0xC0000000), deactivate SD Card and connect eMMC. Unfortunately - there can be active only one storage - SD Card or eMMC. First - we need to write u-boot.s32 file to eMMC. You can get list of commands by help command. Boot from SD card and stop booting by pressing any key when you see first numbers on terminal window. You can also use DHCP server - but this is not part of this document. I used static IP addresses on PC Host side and EVB. Make sure that both servers (nfs,tftp) are accessible from other machine (you can use S32V234 EVB started from SD card for that). This issue is probably related only to ubuntu.
Here is my entry for /etc/exports file for NFS: /rfs 192.168.1.0/24(rw,no_root_squash,sync) and here /etc/xinetd.d/tftp file: service tftp It looks like that in ubuntu is some bug and I have to move tftp files location from /tftpboot to /svr/tftp The tftp file in /etc/xined.d/ remain unchanged. Also make sure that all rootfs files are owned by root. Please look at internet for more details about NFS and TFTP How do I install and run a TFTP server? - Ask Ubuntu Don't forget add into root file system files Image, s32v234-evb.dtb and rootfs.tar - we will need them later f or boot and rootfs partitions. Host PC machine with Linux OS, NFS, TFTP server and network connectivity with EVB NFS shared folder with BSP Linux root file system (the root.tar file located in \s32v234_sdk\os\build_content.tar\build_content\v234_linux_build\ ) tftp server with Image, s32v234-evb.dtb and u-boot.s32 files putty or other terminal connected to s32v234 EVB (tested with minicom on Linux) Procedure Setup NFS share and TFTP server. Requirements Prepared SD Card with linux image (HOWTO: Prepare A SD Card For Linux Boot Of S32V234-EVB Using BSP From VSDK ) and with u-boot.s32 file in boot partition.
