Note: If the root filesystem is shared then this maintenance only needs to be carried on one Parallella (and not for each SD card). a keyboard, mouse, screen if the Parallella has been booted with HDMI support.a remote SSH session after the ssh-server has been set up on the Parallella, or.the USB serial console which provides a root session, or.This needs to be done within a session on ( one of) the Parallella using: Once fully set up and running, the root filesystem will need to be managed and maintained as normal, (e.g. The NFS directories are available for viewing (and editing) on the NFS Server host. Some minor edits to the configuration files are usually needed to ensure that the NFS variant works smoothly in a network environment. Similar steps need to be taken to create the root filesystem contents of the NFS mounted directories - but the process is (usually) much quicker and more flexible. The instructions are then repeated for each physical SD card required for each Parallella in a cluster. The Official (and Unofficial) sources of Linux root filesystems for the Parallella provide instructions for extracting and 'burning' the contents to SD card. Note: The image files follow the same naming convention as for SD card booting. Test_new_kernel/ // boot mode = temp testing variation Headless_7010/ // boot mode = Zynq 7010 Parallella configured as headless Hdmi_7010/ // boot mode = Zynq 7010 with HDMI support The TFTP service directory layout (for this example) will look something like: hdmi_7010įollow the instructions for creating the SD card (download, extract and rename the kernel uImage, and devicetree.dtb files) but instead of 'burning' to a SD card simply copy the image files to the boot mode directory (as root). ).Ĭreate a Boot Mode Directory and Prepare the Image Files sudo mkdir -p /srv/tftp/ // replace with boot mode, e.g. ![]() A breakdown of the bootscript to show different options.Use of mkimage to convert the bootscript text file into a U-Boot script image file.An example bootscript for TFTP boot and NFS root filesystem.Changing the U-Boot boot command to fetch a small bootscript file using TFTP.Setting up NFS and a directory layout for NFS root filesystems, allowing a choice of root filesystems for each Parallella.in the U-Boot 'bootargs' rather than devicetree. ![]()
