I am trying to boot the hardware. I am following link to boot it up Morello Development Platform and Software Getting Started Guide (arm.com).
However, there is no display as it is mentioned in the link too. Do I have to format SATA SSD to boot the system? or there another way?
The installation of the OS into the Morello board should format the SATA SSD in the board. So manually formatting should not be necessary unless you plan on booting from the SSD instead of a bootable USB. In this case, there are instructions on how to do this in the Morello development board getting started guide under the “Setting up the Morello Hardware Development board” section. https://developer.arm.com/documentation/den0132/0100/Setting-up-the-Morello-Hardware-Development-Platform
