ZCU102 faster boot via JTAG combined with network interface (e.g. 20x faster)
Speedup of system boot times
A JTAG link allows a boot of a zcu102 linux system that takes approximately 28 minutes (maybe longer for big system images).
The zcu102 board has a network interface supported by U-boot, and using this allows transferring a system image and booting to a linux login to take approx. 75 seconds.
By suitably configuring U-boot default_bootcmd on the ZynqMP board to use tftpboot, a "petalinux-boot --jtag --u-boot" can trigger a network based download and boot of image.ub from your tftp server (which has usually been setup as part of the tools install). This assumes that your petalinux-build is updating files in area /tftpboot (I believe this is the default).
The attached text file shows some verification tests and then how to set it up with a command like:
