Armbian Jammy (Minimal CLI) boots/works fine from an SD Card. (Armbian_23.5.2_Nanopi-r1_jammy_current_6.1.30_minimal.img.xz)
apt update && apt upgrade -y && apt autoremove
apt install armbian-config -y
armbian-install
I choose option #2 - Boot from eMMC - System on eMMC
Accept the warning.
I choose option #1 - ext4
The install appears to move along smoothly.
I choose the "Power Off" option.
Pull the power, remove the SD Card.
Reconnect the power.
I never see the "heartbeat" on the "System"(red) LED.
The NanoPi never boot or obtains an IP address.
