While you can load and test new custom applications quickly, the configuration of the FPGA is loaded from the QSPI flash. This saves time compared to using the method System Developer. When doing so, follow What must be done when using this method?

1. Make sure that you have a suitable boot loader in your QSPI flash, see Boot Loader. This must be done only once as long as you don't overwrite it.
2. Set the jumpers on your MicroZed board as follows
   .
   This will boot the device from the QSPI flash.
3. Cycle the power. The settings of the jumpers will be read only at power-on! Hence, make sure to cycle the supply power after changing the jumper settings. A soft reset (through the JTAG or by pressing the reset button on the board will reset the board but will not sample the boot mode pins connected to the jumpers.
4. Create a deep project and setup the project configuration as given in Hello World on the Avnet MicroZed Board. Make sure that you have set the OpenOCD command and command options so that it suits your installation, please refer to Setting Deep Preferences.
5. Do not specify a configuration for the FPGA part, as it will be loaded from flash.
   .
6. When creating the run configuration, set the target configuration to boot from flash memory and load program to ram .
7. Run will compile, link and download the image file. See Hello World on the Avnet MicroZed Board for guidance about necessary installations and properly connecting the target.

1. reset (by JTAG)
2. load and run first stage boot loader from flash
   1. configuration of PLL, clocks, DDR
   2. load PL
   3. handoff to JTAG
3. halt
4. reset REBOOT_STATUS register
5. download of bin-files to OCM and DDR
6. download of bit-file (if specified)
7. start at address 0x100
