Binary Export (to SD)

To be able to work with the UltraZohm without flashing it before each usage, a bootable binary can be generated. This binary replaces the default BOOT.bin and the custom code executes after power-cycle of the UltraZohm.

Generate boot image

1. Open the UltrZohm workspace in Vitis

2. In the top menu, select``Xilinx`` -> Create Boot Image

3. Select Import from existing BIF file (radio buttons)

4. Set the Import BIF file path to ~vitis\software\BootImage\GenerateBootImage.bif (see Fig. 37)

Fig. 37 Select existing BIF file.

5. Adjust the file paths at Boot image partitions (see Fig. 38) since the .BIF file uses absolute paths

6. Select each of the boot partitions, select Edit and browse to their absolute path on the local machine

7. Alternative: Change the path to the boot image partitions in the corresponding sub-menu (see Fig. 38)

   • Option 1: Exchange everything before \vitis with the path to the UZ-repo

   • Option 2: Exchange everything before \vitis with as much “.." as you have folder-levels to your repo-path. If you have the correct number, Vitis stops writing “partition file does not exist”

8. Select create Image

Change BOOT.bin on SD-Card

1. Shut-down the UltraZohm

2. Unplug the power connection and make sure that power is off

3. Remove the SD-Card

4. Connect the SD-Card to the local machine

5. Copy BOOT.bin from the uz-repo\vitis\software\BootImage folder to the SD-Card of the UltraZohm (replace the existing BOOT.bin

6. Plug in the power connection and power-cycle the UltraZohm
