Choryu Park Posted September 20, 2017 Posted September 20, 2017 (edited) Hmm... I have similar problem for Asus tinkerboard hangs thread's thing. First, I've reinstall OS few days ago, because OS partition is crashed by system hangs. I've test next build but it can't be reboot (I don't know why). cause I've install legacy build. It looks pretty works well, so I've install 'transmission-daemon' to build my own seedbox. I've plugged 500GB 2.5in External HDD and 128GB Flash Drive, and use 3A Micro-USB adapter. then... ta-da! system hangs! generally It works good 1~2 days after boot. but randomly hangs. I think it's temp things cause install Fan on 3.3V GPIO, but same. It hangs. Before install External HDD and Flash Drive, It never hangs! I think problem maybe caused by; 1. Flash Drive 2. 3A PSU 3. 'transmission-daemon' So, I will try 'Direct connect power to 5V GPIO', and question is this. Can I use 5V 4A PSU? by this video, Tinkerboard's max consumption is 2.2A. External HDD + Flash Drive's consumption is 1.0A ~ 1.2A (expected) So, I need more then 3A PSU, but Tinkerboard can supply over 3A to GPIO Pin? and, I know GPIO Power supply is sensitive to Voltage. It's correct? then how can I protect circuit? First, I will try to remove Flash Drive of this weekend. Tinkerboard installed on my uncle's home, cause I can't manage/test on weekdays. Thank you. Edited October 11, 2017 by Choryu Park solved.
TonyMac32 Posted September 20, 2017 Posted September 20, 2017 Do you have any logs to share? More amperage won't help, the problem is voltage drop, which increases with amperage consumed. GPIO can supply a decent amount of power, I would not be overly concerned of the consumption. While long term you can't pull 4 amps, in short bursts it is achievable. If there is concern, I would make sure to attach to both 5V and 2 gnd pins (The 2nd ground pin is a few pins over from the 3 typically used.)

I will bring Tinkerboard to my home on weekend, then check and provide log! So, ok. I will try to decrease power consumption (disconnect USB or something), and connect 5V 3A PSU connect directly to GPIO. If it fails, I'll post here. Thank you!

A next thing co, c.h.i.p - Have no idea what that draws. I did attach a 5200mah battery in charge mode along with the above which was happily charging away until I killed the board running stress in a stupid manner, it would not boot again with the battery attached, so I suspect the battery screamed "I want more" & was duelling it out with the others, when the power was returned to the board, En GARDE! --- The armbianmonitor output looks wrong (to me), surely it should've gotten much hotter? The drop down to 600MHz was when openssl finished. I can't be sure whether the drop to 1704MHz was also because openssl had finished or it throttled? I've also purchased a usb doctor thing to measure the draw so should be able to give the result of that too when it arrives. Edited September 20, 2017 by Tido added spoiler

Igor Posted September 20, 2017 Posted September 20, 2017 5 minutes ago, mpmc said: I've also purchased a usb doctor thing to measure the draw so should be able to give the result of that too when it arrives. This board without anything attached consumes (at peaks) more power that it's possible to deliver via microUSB connector. Some might work, but most not. Mighty ASUS sold you board failed by design. Board will crash even you attached the cable to the source which is able to deliver 100A at 5V. Is this clear? If not, check some insights: https://forum.armbian.com/index.php?/forum/31-sd-card-and-power-supply/ GPIO powering with better PSU and USB stuff attached via powered USB hub is the only way if you want to stress your board.
mpmc Posted September 20, 2017 Posted September 20, 2017 @Igor I'm already aware of the limits of microUSB Adding "Is this clear?" really wasn't needed, makes you sound stressed . And, yes I've already read those posts . This board without anything attached consumes (at peaks) more power that it's possible to deliver via microUSB connector. Well, this NorthPada adapter must be certainly able to handle it as It hasn't once crashed for the past few weeks, I've left it alone for 5 days (without a reboot) & went to check it was still up, uptime said 5 + days, so no reboot had occurred. I crashed it myself using stress trying use more RAM than allowed (just to see if I could) . --- Please bare in mind I'm only testing whether this adapter is able to keep the board alive with some devices & so far it has, I'm not expecting it to be able to power a dozen devices and the board without some issues, that would be stupid.

You can attach whatever you want with an amperage rating as high as some thousand amps to a Micro USB port and it won't help since it's not about amperage but about voltage drops. In my opinion boards with a boot peak consumption above 800mA that use this shitty Micro USB connector by default should be phased out. You either had luck so far or by chosing a PSU that is advertised to power shitty devices by design you chose one that is prepared to compensate for the Micro USB voltage drops (then it's a 5.25V PSU and not a 5V PSU). But even if your PSU is prepared for those voltage drops the situation with Tinkerboard is still just a shit show since Micro USB is not specified for anything higher than 1.8A -- just grab a magnifying glass and look at those laughable tiny contacts. If you like pictures like that below just give it a try to overload these tiny contacts with a 3A load. Please take a video and upload it somewhere so we can all have a laugh.

Do you own it? Do you have experience how good it works? 60$ for a 300mAh LiPo, charger circuit and MCU. This plus and a *random MCU* should do the same job. (Ok, 500mA less output and input voltage is more limited, but for a price of around ~10$ with MCU, instead of 60$.)
Torgar Posted September 20, 2017 Posted September 20, 2017 Has no experience with the product. Just wanted to share information about a product tailored for Tinkerboard. I agree that it is not cheap!

Sorry, but there is exactly NOTHING tailored for Tinkerboard, it's just the same thing as this RPi add-on for €5 less: https://shop.olmatic.de/de/usv-raspberry-pi/2-susv-pi-advanced-4260434190029.html -- most probably you pay €5 more since they needed to replace a Raspberry symbol with a Tinkerboard logo in their advertisements and on product packaging. Raspberries are based on a TV box SoC, have no PMIC and so you need such expensive 'UPS' add-on boards if you want to run Raspberries from battery. Tinkerboard is based on a tablet SoC combined with an appropriate PMIC (power management IC capable of charging / control a battery). If the Tinkerboard would not be such a horrible design fail all that's needed there to provide 'battery capabilities' would be a battery connector attached to the PMIC (and maybe some boost converter somewhere). The RK3288 is made for tablets and laptops (Chromebooks) designed to run mostly from battery, it's almost insane to combine a RK3288 based board with faulty power design with such an expensive battery thingie. To get the Tinkerboard powered reliably all that's needed is just either desoldering the shitty Micro USB jack to replace it with a more suitable barrel connector or to power it with suitable cables through GPIO pin header in the first place (using 2x5V and 2xGND pins). This will both prevent undervoltage situations and crappy Micro USB equipment melting once you need to feed more than 2.5A continually.
mpmc Posted September 22, 2017 Posted September 22, 2017 Update: I'm happy to report that my tinkerboard and northpada power supply - are still alive and in one piece (including the cables/connectors, yes I checked) - after being continually under load for almost three days. The board (under a GPIO connected fan) and psu got warm, but not hot to touch at any point, the microusb connection on the board, never once got warm. BUT: @tkaiser is right - even if the manner he goes about it is less than tactful - the board should be powered by GPIO. But in my case, headless usage with only a few devices connected, I don't foresee any issues. So if you plan on powering by the microusb connector (which isn't recommended ) it should be okay with a decent PSU, well in my case it is, but YMMV. 1

mpmc Posted October 28, 2017 Posted October 28, 2017 Just thought I'd pop in to say my tinkerboard has been powering a C.H.I.P and an FM transmitter (500a) for 20 days+ now without much issue.
