I used my power bank with 2.1A I thought that would works. It was working with the power bankbefore started the issue

Sure. You're not alone: http://tinkerboarding.co.uk/forum/thread...tml#pid225

That's due to crappy Micro USB used for DC-IN. All powerful SBC using Micro USB suffer from this problem and it's pretty amazing that ASUS ships a board in 2017 featuring the same mistake! Smile

Your cabling is insufficient and even if everyone will tell you here it's about amperage ratings it's not since 2A are pretty sufficient if you only run light loads on your board. The real problem is called under-voltage related to cable diameters (cable resistance --> voltage drops) and connectors with contacts too tiny (contact resistance responsible for another voltage drop). 

If you want to see a nice review showing exactly your symptoms and how to workaround or even fix it: https://forum.armbian.com/index.php?/top...ment=31711

Unbelievable, was the crappy wire well I have some confusion because I tested the device with 4 different wires I didn't realize that detail about the wire.

Thanks a lot!

It's almost always the wire (and almost 100% of USB cables lying around have a resistance way too high for powerful devices like the Tinkerboard) but unfortunately this micro community suffers from users not knowing about and even people denying this, see here for example: http://tinkerboarding.co.uk/forum/thread...tml#pid889 (and as long as some people continue to tell new users suffering from instabilities they should 'use a larger power brick' nothing will change!)

Some great observations regarding powering and (insufficient) heat dissipation: https://forum.armbian.com/index.php?/top...ment=32018

With Armbian we'll recommend to power Tinkerboard only through GPIO header from now on (pins 2/4 == 5V, pin 6 == GND) since it sucks so much getting reports about instable software that are in reality only related to the shitty Micro USB connector encouraging Tinkerboard users to use average (99% insufficient) USB cables.

To paraphrase....  Confused

I bow to you greater knowledge and expertise. so what gives @tkaiser, are you enjoying your Tinkerboard, its a great product, would you agree ?...

Thank you ravd13 Used the cable that came with Sony 2.1 A 5V DC Power supply and TinkerOS booted to life. We were using a thinner Belkin charge cable before. You're right... cable diameter does matter.
