I have downloaded http://mirror.igorpecovnik.com/test/Armbian_5.00_Bananapi_Debian_jessie_4.4.0-rc5.zip and tried OTG, as I though that it´s support was added in kernel 4.3, but it is not wokring. Is there a way to enable it? I am missing this feature, yet I do not want to go back to legacy kernel.

 

I tried various usb peripherals and hubs, but OTG port is not powered. 

 

Thank you.

That image was deliberately compiled with OTG in host mode   

 

You need to alter Bananapi DTB ... Simply use the one from BananaPRO and it should work since OTG mode is default.

My luck is bad here Igor. port still dead.

 

To be sure I have compiled whole own kernel too. First time with "host", second time with "otg" option in sun7i-a20-bananapi.dts (I have deleted source dir before second attempt). Nothing changes.  (I have installed both new kernel and dtb .deb files)

 

I do not know where I could make a mistake. Chrrrm. Maybe port is broken physically. 

 

I will just wait to next release and will see what is up. 

You need to load a module "sunxi"

Loaded sunxi module (modprobe sunxi), lsmod shows it, but OTG is still not powered. 

 

EDIT: Just installed 3.4 kernel and after script.bin modification OTG works OK. So it is not HW problem.

FYI, I probably have the same issue on lamobo-r1, I was never able to use the "OTG" microusb port

Try to use bin files from Bananian images https://www.bananian.org/download.

Download image of Jessie for example, unpack zip folder and you can mount image with gnome-disk-utility (gnome-disks command if you are running Ubuntu based system).

When is first partition mounted go to fex/BananaPi-OTG/. I think you just need to replace script.bin in your armbian image or just part of it.

The problem is in kernel 4.x ...

I have armbian with kernel 4.4 and it works out of the box... 50%. If I use a Y connector (power from another USB and data from otg port) it works correctly. It is not a problem because I have USB power nearby and a stock Y cable, but it is not they way it is expected to work (In fact I was going crazy until I read in another post from Igor that port is not powered)

Powering USB OTG port on Banana Pi is not implemented in mainline kernel - it is wired in non-standart (compared i.e. to cubietruck) way. In theory it's possible to do it manually, but using Y-cable should be more safe anyway.

Hi to All,

 

I also try to use USB OTG on Lime 2 board without success.

I use Armbian (from SVN) customized and build by me with U-Boot 2016.05-rc1 and kernel 4.5.2.

After checking sun7i-a20-olinuxino-lime2.dts (generated by dtc) I apply proposed by Igor patch:

... 
 &usb_otg {
-	dr_mode = "otg";
+	dr_mode = "host";
 	status = "okay";
 };

compile dts file to dtb and copy it back to /boot/dtb.

Unfortunately, USB OTG did not work but I see following inside boot messages:

[    3.369524] sun4i-usb-phy 1c13400.phy: could not find pctldev for node /soc@01c00000/pinctrl@01c20800/usb0_id_detect_pin@0, deferring probe

I do not change anything else and verify that there is dts node for usb0_id_detect_pin.

 

It is strange to see sun4i-usb-phy ... and why usb0_id_detect_pin is used in case of selecting HOST only mode?

 

Where could be the problem?

 

EDIT: I go back to dr_mode = "otg" and find that probably USB is recognized in both cases but usb0-vbus is disabled for some reason:

To verify if the problem is in USB OTG powering I have connected to it a self powered device.

Unfortunately, it does not work while connecting it to one of the USB Host ports it works.

 

Best regards
