Hi ,

I just move my banana pi pro which was running bananian  up to now to buster minimal.

I'm using it as domoticz server. It requires few usb port to have all my gateway working.

So I need to make USB OTG running in HOST mode.

 

I did lot of testing, read many thread, but quite stuck right now.

Here is what I have already done :

 

First I have activated in DTB usb@1c13000 , and change mode to host. I have also activated usb0-vbus.

I added also regulator-boot-on in usb0-bus. and last test I did is adding usb0_vbus-supply = < 0xb1 >; in phy@1c13400.

 

For those who may need later on, here is the command I did:

$> cd /boot/dtb

$> sudo cp sun7i-a20-bananapro.dtb sun7i-a20-bananapro.dtb.org

$> sudo dtc -I dtb -O dts -o  sun7i-a20-bananapro.dts sun7i-a20-bananapro.dtb

$> nano sun7i-a20-bananapro.dts

$> sudo dtc -I dts -O dtb -o sun7i-a20-bananapro.dtb sun7i-a20-bananapro.dts

 

$> sudo dtc -I dtb -O dts -o  sun7i-a20-bananapro.dts.org sun7i-a20-bananapro.dtb.org

$> diff sun7i-a20-bananapro.dts.org sun7i-a20-bananapro.dts

<         status = "disabled";
---
>         status = "okay";

 

In /boot/armbianEnv.txt, I added

overlays=usbhost0 usbhost1 usbhost2 usbhost3

 

When the board boot, since I added  regulator-boot-on;, I can see the peripheral connected on the USB OTG port getting power.

But later on, usb0-vbus is disabled and I don't know why.

I don't know how to re-enable usb0-vbus. Is there a module missing?

 

If you have any advice .

Nota; I have to figure out why I have those phy0 failure, but wifi is working well.

 

 

Looking at @sooperior thread, where @dryce seems to make it working using SimpleNAS DTB, I'm wondering if I have a missing change in my current DTB, or if it is just normal difference because not based on same parameters.

 

Not clear yet for me if I have to add in phy section equivalent line

 usb0_id_det-gpio = <0x25 0x7 0x3 0x0>;
