[[OPiOne] USB power off]

No, I was talking about touching /boot/script.bin directly for a reason. Since /boot/bin/orangepione.bin (and all other files in this directory) are not under your but our (Armbian's) control. Next update that will be rolled out will overwrite your changes (and this will happen most probably within one week). So overwrite /boot/script.bin with modifications and don't let this be a symbolic link to a file in /boot/bin/

 

BTW: I second @chwe's concern and would suggest testing your dongle on a good USB3 port (known to provide stable 5.x V at 900 mA -- I tested this a while ago with a couple of laptops and a Banana Pro to be able to measure and with almost all PC laptops power situation on the USB3 ports sucked especially when switching the laptop over to battery)

1) Ops, i've seen that script.bin it is symlink and decided rewrite original. I will change post.

2) I don't think so. I'm used this dongle on many device. it can work fine one month or can freeze in first day. If I'm not mistaken it consumes ~ 100 mA

I don't know this your Huawei E171 stick well, to my bad most of the information is in Cyrillic letters so I don't understand anything. 

But I think this cellular sticks can be relatively power hungry (I had problems with a cellular stick on an old notebook years ago). Could this be the problem?

If you knew how Huawei sounds and what it means in Russian, you would understand why it freeze after few days . Something like "piece of .... " but worse  It works normal only as VoIP gateway on asterisk(more than 1 year uptime). I've seen same problem on routers, desktop pc and now here. I think it is modem hardware or software problem.

Thank you very much tkaiser! Thank you all!

Works great! Problem solved!

 

Message to descendants :

1) Taking out of control of the respective driver

# cd /boot

# bin2fex ./bin/orangepione.bin > newbin

# nano ./newbin

Change line 'usb_drv_vbus_gpio = port:PL02<1><0><default><0>' on 'usb_drv_vbus_gpio = '

# rm ./script.bin

# fex2bin ./newbin > script.bin

# rm ./newbin

!REMEMBER! - after reboot power on USB OTG port will be OFF by default!

# reboot

 

2) Export gpio pin PL02.

To obtain the correct number you have to calculate it from the pin name. Use this formula:

(position of letter in alphabet - 1) * 32 + pin number

(HL02) letter L - stay on 12 position in alphabet.

(HL02) pin number - 2

result:

(12-1)*32+2=354

Use GPIO sysfs do next:

# echo 354 > /sys/class/gpio/export

# echo "out" > /sys/class/gpio/gpio354/direction

Power ON

# echo 1 > /sys/class/gpio/gpio354/value

Power OFF

# echo 0 > /sys/class/gpio/gpio354/value

 

Enjoy!

Shouldn't this be possible with the OTG Port by toggling PL2?

 

Edit: But restart isn't really a nice approach to solve your issue not?

 

It's very interesting, what i need to do to "pull this trigger"?

 

Restart is acceptable but helpless after # reboot modem still frozen

No, not with OPi One (and other H3 boards). AFAIK the only boards that really support this are Olimex boards with A10 or A20 SoC. See also https://forum.armbian.com/topic/1631-marriage-between-a20-and-h3-ups-mode-sunxi-pio-utility/

Yes, I read it and even tried this:

orangepi

PH26<1><0><default><0>

PH22<1><0><default><0>

It is necessary to cut the wire 5V in the OTG cable and connect via a relay Last chance.

 

Thank you tkiser for your fast and useful respond.

Hello friends!

I Am using 3G modem(Huawei E171 connected by OTG cable) on my OPi One for internet, but one problem - modem after few days working freeze. Reboot don't help because not full power off on USB, and after reboot i don't see modem in /dev. Only after physical remove modem and install again it's initialized and work fine.

 

Question: Can i power off USB from cli?
