Enabling usb otg on banana pi m1 A20

Recommended Posts

Hi All,

I'm trying to get usb otg enabled as host mode to add, for instance, a keyboard with a powered hub (I know otg is not delivering power or at least I don't want to drain more power with the otg)

 

I'm using vanilla kernel 4.8.4 so I kind of expect otg enabled as host mode by default.

 

Anyway, I get into dts and make sure this section:

usb@01c13000 {
compatible = "allwinner,sun4i-a10-musb";
reg = <0x1c13000 0x400>;
clocks = <0x2 0x0>;
interrupts = <0x0 0x26 0x4>;
interrupt-names = "mc";
phys = <0x30 0x0>;
phy-names = "usb";
extcon = <0x30 0x0>;
allwinner,sram = <0x31 0x1>;
status = "okay";
dr_mode = "host";
linux,phandle = <0x6e>;
phandle = <0x6e>;
};
 
has status=okay and dr_mode=host
 
Driver seems to be the problem, I get this message on dmesg
[    4.516751] usb_phy_generic.0.auto supply vcc not found, using dummy regulator
[    4.517180] musb-hdrc musb-hdrc.1.auto: musb_init_controller failed with status -16
[    4.517230] musb-hdrc: probe of musb-hdrc.1.auto failed with error -16
 
#modprobe sunxi does nothing
google shows only one result for this error
 
 
Any ideas for troubleshooting?
 
 
I've also been looking for ideas in this thread https://forum.armbian.com/index.php/topic/385-banana-pi-usb-otg/but it seems to show the steps I have followed

I also have many problems with USB OTG on Lime2 (A20) boards and customized Armbian build with mainline Kernel.

The problems and some of the solutions are described in some posts on this forum thread.

 

Best regards

Chris

Interesting... but this thread is more or less about otg in "otg mode" or reliability issues, but I'm not able even to get anything detected.

What is driving me crazy is this error:

[    4.516751] usb_phy_generic.0.auto supply vcc not found, using dummy regulator
[    4.517180] musb-hdrc musb-hdrc.1.auto: musb_init_controller failed with status -16
[    4.517230] musb-hdrc: probe of musb-hdrc.1.auto failed with error -16
 
There is almost no info about that on google, I'm afraid it could be something armbian-specific
 
PS: I'm not  using any custom kernel, just out of the box armbian 5.23 with kernel 4.8.4

On OPiOne and OPiLite, there was similar issue that reg_usb0_vbus was not present.

I've fix that a month ago with this commit :

https://github.com/armbian/build/commit/fb0d3c6ea4b06df236d198af825d31a073dd2b81

Maybe similar patch could fix it on BananaPro ...

That would be great. Do you know how similar the two devices are?

Looking at both schematics and DTS of BananaPro-A20 and A20-OLIMEX-MICRO, (I've some Olimex myself and I know OTG is working on them), it seems probable that BananaPro-A20 is only missing things are the following in Mainline DTS :

&reg_usb0_vbus {
        status = "okay";
};

&usb_otg { 
        dr_mode = "host";
        status = "okay";
};

 Still seems like something is missing. The A20-OLIMEX-MICRO dts sets additional parameters:

usb0_id_det-gpio = <0x29 0x7 0x4 0x0>;
usb0_vbus_det-gpio = <0x29 0x7 0x5 0x0>;
usb0_vbus-supply = <0x34>;

 

Wouldn't the Banana Pro require this as well?

The problem here turned out to be with the device tree blob. For USB OTG to work properly with the Banana Pro the file should look like the one attached. I now have an up to date Armbian install with a working OTG port. I can't take credit for making the changes. The device tree blob came from a SimpleNAS build for the Banana Pro. The default Armbian dtb seems to be missing a few needed values. @Igor could these changes be integrated into your code? Hopefully, this helps someone else get this working. Thanks for all the hard work.

It's up to the user to configure the board upon his use case.

 

Simple host/OTG mode switcher from armbian-config and DT adjustment is on the 2do list for some time. If we do it, we have to check on all boards. Not long ago there were troubles with OTG mode, so this was pointless to implement. Perhaps still is?

In case you find something generally useful: https://docs.armbian.com/Process_Contribute/

The file has several differences throughout compared to the armbian version. These are just a few of note. The values for some of the above properties are different in the default file vs the SimpleNAS dtb I used. I don't believe the OTG port was getting power before. There are other property differences throughout and everything appears to be working without issue.
