Hello,
I am trying to use g_serial but it does not work.
I'm using fresh install of armbian (Armbian_5.38_Orangepilite_Debian_stretch_next_4.14.14.7z),
with apt-get update/apt-get upgrade/armbianconfig Install headers.
Linux orangepilite 4.14.15-sunxi #28 SMP Mon Jan 29 07:24:48 CET 2018 armv7l GNU/Linux
This is the overlay I use to enable OTG:
sudo /usr/sbin/armbian-add-overlay usbotg.dts
/dts-v1/;
/plugin/;
/ {
compatible = "allwinner,sun8i-h3";
fragment@0 {
target = <&usb_otg>;
__overlay__ {
dr_mode = "otg";
status = "okay";
};
};
};
After rebooting OPi there are several errors like this in syslog
musb_g_ep0_irq 712: SetupEnd came in a wrong ep0stage out/status
The other computer is running Ubuntu 16.04 LTS
I use small USB hub (full speed only) between my PC and OPi lite but if I make direct connection the errors are same.
If I unplug and plug USB cable between OrangePi Lite and my computer (or if I plug the cable after OPi boots) I get same errors.
I got same errors when trying with .g_ether

The result of sudo armbianmonitor -u is here http://ix.io/Fcb
