New install on a clean build

    * Nano Pi M4 v2 4Gb, new out of the box
    * rk3399-eflasher-friendlydesktop-bionic-4.4-arm64-20200916 image on 8Gb Micro SD
    * No hats. Only peripheral is USB keyboard. Ethernet connected. USB-C power. HDMI screen.

On boot shows the green & blue FriendlyElec GUI splash & smiley face, then briefly below it in grey "Powered by RK3399"

LED's rotate Red5 secs, Green 2 flashes.

Continuous loop.

Can I access anything before the splash, to pause it or see console?

Recommended debug actions? Serial console? Inspect /var/log on root fs on SD card? Any other magic keysequences? Firmware update?

Is this expected on new installs?
