zynq_flash

Is a command-line tool from Xilinx to write nonvolatile memory connected to Zynq PS. With current versions of tools there is minor problem with file extensions: on windows platforms only lowercase .bin is accepted as extension. Boot bin generated with petalinux would be howeve generated as BOOT.BIN with uppercase extension. It is not possible to use it with Xilinx SDK Flash Programmer GUI or the commandline zynq_flash. GUI Flasher will not allow to select a file with upper case extension, and zynq_flash will also refuse to flash from it if the file is given with uppercase extension. As a workaround the image to be burned has to be renamed with lower case extension (.bin).

BOOT.bin

File order is important when creating Zynq Boot image with Xilinx bootgen, BITSTREAM if present must be specified as second file, before application and second stage bootloader (normally u-boot). If not the Xilinx standard FSBL will give an error.
