No Image on PSPi

Possible Causes and Solutions:

1. CM4 Carrier Switch Position:

   • Verify the switch is in the correct position:
     • SD/eMMC position: When booting from SD card or internal eMMC
     • USB Boot position: Only when flashing firmware or OS to CM4

2. OS Flashing Issues:

   • Verify the OS was correctly flashed to the SD card
   • Use Raspberry Pi Imager for flashing
   • Check that the SD card is in good working condition

PSPi Not Fully Booting

Issue: System doesn't complete the boot process.

Common Cause: Custom username and password settings in Raspberry Pi Imager.

Solution:

• Avoid setting custom username and password for RetroPie or Lakka images
