SD card burn img size problems

@kaiser, I will look into this.

Please look into this too: http://forum.pine64.org/showthread.php?tid=2115&page=2

A whole thread where people are talking about DOA LCD panels while they're most probably just suffering from boards not booting for whatever reasons (burning failed, SD card broken, whatever).

Edit: And here we have the other variant: Undervoltage due to higher power requirements caused by the LCD backlight? 'Flashing' power led is not a software thingie: http://forum.pine64.org/showthread.php?t...9#pid20349

Simple question: What does it need for the LCD's backlight to turn on?

• Providing power through Micro USB or Euler pins?
  
• U-Boot and/or kernel loading regardless of settings?
  
• U-Boot and/or kernel loading and LCD activated (via this setting)?
  

Next simple questions: How much amperage needs the LCD backlight with default settings? When dimmed through PWM could that add to noisy power behaviour?

This is something you as the vendor should be able to answer and if this is known it gets easy to diagnose 'LCD problems' or to be able to differentiate 'LCD' from 'board not booting' problems.

Might it be a great idea to add a custom led on the board with a new PCB revision should you plan to update Pine64/Pine64+ anytime soon? For an OS being able to indicate »I'm doing this and now am doing that«.

BTW: Wiki still not updated.
