Hi!

 

I have recently installed Armbian 4.5 (Debain Jessie and Ubuntu trusty) at Banana Pi M2, and I’ve noticed that the computer doesn’t reboot after the command. It simply switches off, and the red diode lights up.

 

How it could be corrected?

Hello,

 

does

sudo reboot -f

work better? if yes, there is a script problem, if no, hardware or dts config issue (only a finger crossed guess)

 

see "man reboot"

 

regards,

Guillaume

Hi, wildcat_paris.

Unfortunately I could't check earlier, but today I have tried your decision and it didn't work.
After command "sudo reboot -f" Banana Pi M2 simply turns off

@zendus

I have moved the topic, hoping a user owning the board can help.

 

I have just read http://www.armbian.com/banana-pi-m2/ please edit your topic: are you using Debian Jessie or Ubuntu Trusty? I read "Jessie fails to boot on some boards."

@wildcat_paris thanks for moving the topic.

I tried Debian Jessie and Ubuntu Trusty, the problem is on both images.
 

It Looks like the same I had at the beginning...

 

In my case it was a power supply issue:

- DO NOT power the M2 via micro USB, ONLY via barrel plug (4/1.7mm)

- the power supply it self should also be a good and sufficient one

 

hope that helps

DO NOT power the M2 via micro USB, ONLY via barrel plug (4/1.7mm)

 

This is also important since otherwise 2 of the USB ports won't work. Can you please confirm if it's necessary to press the power button when you use USB OTG to power the board (if this is the case then the reason why 'reboot' always ends up in 'shutdown' is already explained)

Yes, I am using power supply via micro USB, two USB ports don't work.
Unfortunately, I don't have a power supply with a barrel plug (4/1.7 mm), and now can't check.
But I had already ordered, will be sent to accomplish your goal

 

P.S. Forgot to write, from the "Power" button the computer will not turn on.

Ok, please keep us informed whether the problem persists when powering the board through DC-IN instead of USB OTG. And then please create an account at linux-sunxi.org and add this information here: http://linux-sunxi.org/Banana_Pi_M2

 

BTW: Not a recommendation (since I've no idea whether this specific cable suffers from voltage drops as many other USB cables): http://www.ebay.com/itm/USB-A-Male-to-4-0x1-7mm-DC-Power-Adapter-Cable-Charger-Supply-5v-For-Sony-PSP-/391213497404?_trksid=p2141725.m3641.l6368&afsrc=1&rmvSB=true

 

I just remembered I read somewhere about it...

So finally I’ve received AC Adapter.

Firstly I’ve started with checkup, and to my delight I’ve noticed that all USB ports worked, but still nothing changed with the computer after clicking the command “rebootâ€

I‘ve decided to sort the problem out and recorded image Bananian on another microSD. The computer began to reboot with the Bananian, great. Then I’ve put microSD from Armbian again into the computer and the reboot function again didn’t start working. Just for the experiment I’ve recorded Armbian on that microSD where was recorded Bananian and ..hooray, the rebooting start working on Armbian.

Conclusion: it seems that the problem came from the microSD (originally I’ve used Lexar microSDHC 8GB - http://www.lexar.com/products/lexar-microsdhc-microsdxc-cards ), the card is not expensive, but during the testing it showed good parameters for reading and bad parameters for recording (http://www.citilink.ru/catalog/computers_and_notebooks/media/flashcards/301964/rev33842/#readreview). For the alternative I’ve used  microSDHC Transcend.

P.S. After the experiment I’ve checked rebooting  on Adapter through micro USB and with microSDHC Transcend. As a result the rebooting itself worked greatly, but 2 USB ports didn’t functioned as I mentioned it earlier above.
