Solved !
Problem is Ubuntu (2018-09-16-ubuntu-18.04-mate-desktop-demo-aarch64-bpi-w2-sd-emmc.img.zip)
boot enter in infinite loop ending with:
“[AO][_AO_if_video_HDMI_mode]HDMI not enabled”
see below…
with OpenSuse (2018-09-19-openSUSE-Tumbleweed-ARM-XFCE-desktop-demo-aarch64-bpi-w2-sd-emmc.img.zip) or Kali (2018-09-20-kali-xfce-desktop-demo-aarch64-bpi-w2-sd-emmc.img.zip) everything work fine…
Is there any way to choose system at boot time (something like uboot-menu) ?
By sending a command with uart ?
Thanks a lot.
