3.1.3. First-Stage Bootloader
In HPS first boot mode, phase 1 configuration is successful as long as HPS OSC and HPS EMIF clocks are running stable.
For a generic transceiver use case, if the XCVR ref clock is not running during phase 2 configuration, the phase 2 configuration still succeeds.
For a PCIe use case, if the PCIe ref clock is not running during phase 2 configuration, the configuration fails.
