  • Hi,

    I have latest RPi4 and msata SSD connected over USB3 port, with latest firmware:

    # rpi-eeprom-update
    BCM2711 detected
    Dedicated VL805 EEPROM detected
    BOOTLOADER: up-to-date
    CURRENT: Thu 3 Sep 12:11:43 UTC 2020 (1599135103)
    LATEST: Thu 16 Apr 17:11:26 UTC 2020 (1587057086)

    I wen through the Pi4 USB Boot is coming soon!!!! YAAAY but I am a bit lost. Is it supported out of the box or not? What should I do to make it working because at the moment I can hear some sounds in the TV but there is a blank/black screen.
