Boot issue (red light)

[pineitup]

Unless they say what the red light means, it's hard to say, obviously turned on by uboot
Do you still have to push pwr button a second time?
Myself, I'm still on uboot from 19.12, on SD, emmc uboot blanked
I think this (19.12) must be bsp uboot because s3 sleep works, not quite as well as mrfixit

The red light is on as long as uboot is in command. This takes about 15 seconds on my pbp. As soon as the kernel takes over, the led switches to green.
This behavior has been confirmed by a Manjaro dev (@strit).

I see. So why was it so much shorter, pretty much immediately green after pressing the boot button, on the default installation coming from pine64 before any modifications? Isn't there a way to redo the same setup?
