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  :D 

 

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.

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

Chris
