-  - Set the jumpers on your MicroZed board as follows \\ {{ :jtagboot.png?200 |}}. \\ This will boot the device from JTAG. +  - Make sure that you have a default boot loader in your flash device, see [[boot_loader]]. This must be done only once as long as you don't overwrite it.  
 +  - Set the jumpers on your MicroZed board as follows \\ {{ :qspiboot.png?200 |}}. \\ This will boot the device from the QSPI flash. 
   - 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.   - Cycle the power.

   - Create a deep project and setup the project configuration as given in [[first_example_microzed|Hello World on the Avnet MicroZed Board]].    - Create a deep project and setup the project configuration as given in [[first_example_microzed|Hello World on the Avnet MicroZed Board]]. 
-  - If you need a valid configuration in your FPGA part (e.g. you are using flink devices), you must select a configuration file for the PL. \\ {{ ::chooseplfile.png?300 |}} \\ Available configurations can be found under [[https://wiki.bu.ost.ch/infoportal/embedded_systems/zynq7000/microzed]]. +  - Do not specify a configuration for the FPGA part, as it will be loaded from flash. you must select a configuration file for the PL. \\ {{ ::choosenoplfile.png?300 |}}. 
-  - When creating the run configuration, set the target configuration to //load program to ram// {{ :runconfigurationmicrozedram.png?400 |}}.+  - When creating the run configuration, set the target configuration to //boot from QSPI flash and load program to ram// {{ :runconfigurationmicrozedflashram.png?400 |}}.
