Rebuilding the Image Selector Utility
The core of the Certified Ubuntu for Xilinx Devices boot process on ZCU10x boards is the Image Selector tool. This utility performs the initial boot of the board, reads board-identifying information from the attached EEPROM, and then reboots into a customized set of boot collateral for the specific board it is running on. This is what allows the same Certified Ubuntu for Xilinx Devices SD card image to boot on multiple boards. Typically, there is no need to modify this code. If a user determines that they would like to modify the way that Image Selector operates, it can be rebuilt inside the Vitis environment. The source code of Image Selector is part of the Xilinx embeddedsw repository on the Xilinx GitHub.
The Tcl code below automates the building of the Image Selector tool inside of Vitis. Be sure to pass the symbol XIS_UART_ENABLE to see the STDOUT info (as seen below).
