Or download and copy the default firmware bitfile for your RCE to <arch_linux_root>/boot/fpga.bit
For diskless DTMs, use a different filename than DPMs, like <arch_linux_root>/boot/fpga_dtm.bit
wget http://www.slac.stanford.edu/projects/CTK/SDK/fpga.dpm.bit
...
First, update the RCE bootloader (boot.bin) with the version in the latest SDK.
Reboot the RCE.RCE with default firmware (reboot_rce -t linux -b 0)
Boot the RCE into the bootloader.
For non-eFUSE RCEs, make note of the ethaddr variable for later restoration.
Reset Apply the default u-boot environment:
...
zynq-uboot> setenv bootdelay 3
DTM Firmware FPGA Bitfile
DTMs use different firmware bit files than DPMs.
The default filename of fpga.bit must be updated to reflect the name of the DTM file located in <arch_linux_root>/boot.
In this example, the DTM firmware bitfile is named fpga_dtm.bit
zynq-uboot> setenv nfsfpga 'nfs 0x1000000 ${rootpath}/boot/fpga_dtm.bit && fpga loadb 0 0x1000000 ${filesize}'Save the environment and reset:

Read-only ArchLinux ArchL inux Filesystem
In order to make the NFS ArchLinux Arch Linux filesystem read-only to the RCEs, execute this on the NFS host:
...
Once an RCE writes to the filesystem, the root user has ownership of any new files.
Adding Packages to the ArchLinux Arch Linux NFS Filesystem
In order to add packages using pacman, the NFS ArchLinux Arch Linux filesystem must have global read-write permissions.
