zendrus Posted December 28, 2015 Posted December 28, 2015 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?
wildcat_paris Posted December 29, 2015 Posted December 29, 2015 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
zendrus Posted January 8, 2016 Author Posted January 8, 2016 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
wildcat_paris Posted January 8, 2016 Posted January 8, 2016 @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."
zendrus Posted January 12, 2016 Author Posted January 12, 2016 @wildcat_paris thanks for moving the topic. I tried Debian Jessie and Ubuntu Trusty, the problem is on both images.
Holsteiner Posted January 12, 2016 Posted January 12, 2016 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
tkaiser Posted January 12, 2016 Posted January 12, 2016 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)
zendrus Posted January 13, 2016 Author Posted January 13, 2016 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.
tkaiser Posted January 13, 2016 Posted January 13, 2016 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...
zendrus Posted January 24, 2016 Author Posted January 24, 2016 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 “reboot†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.
