I saw that thread. This doesn’t help me much or maybe I’m missing something.
Schematics doesn’t contain layout, so I have no idea how power barrel is connected and how 5V gets to header. If it is connected directly I probably can use pin 2 or pin 4 to provide 5V and power on board in that way. I don’t have board, so I cannot try. Also if this can damage board I would like to know that without trying.
Well after the change in fex file the port will be available to the kernel even if the USB lines aren’t exposed physically. So looking forward to your testing
On a related note: We have just figured out how to reliably use H3 with 3.4.x kernel as USB Ethernet gadget device: http://igor2.repo.hu/tmp/opi_usb_gadget.txt (requires one smallish kernel change and should also work with BPi M3 where it makes not that much sense since only 1 real USB port there is available)
I tried to add this information to linux-sunxi wiki since this subforum seems to be even more dead than the others and as usual SinoVoip doesn’t provide correct documentation (this port is mentioned nowhere, in their chapter about USB OTG M3 and not M2+ is mentioned – so as usual you never know whether this is correct or just the usual copy&paste errors they’re so famous for)
@sinovoip: Do you get the idea why providing correct documentation might matter?
@sinovoip: Do you know why users vanish from these forum? Since you don’t answer even the most simple questions. This is not a community forum since no users are around. The only reason people are posting here is to ask support questions. Like question N°1 above: “Is it possible to power supply BPi-M2+ over header”. Why don’t you answer your user’s questions?
@sinovoip: Do you get the idea why people are not that satisfied? Of course not
@tkaiser, @BPI_Q many thanks for your research and testing. Without this answers it is hard to imaging that people will choose Banana platforms for further project, not saying about serious prototyping.
But even if 100 others tell them they won’t get the idea that respecting their users and answering such basic questions would be a good idea. It’s no wonder that devices like these might be sold to newbies (since they are uneducated and think the new Bananas would be compatible to the good old ones based an A20) but then only collect dust lying somewhere around due to lack of software or even basic information
