Hello. What's the status for usb otg support for gxbb/odroid-c2 for now? Is it possible to run gxbb usb in a slave mode and use gadget modules with it ?

tingoose: it should wotk if you force the mode in DT yes, OTG detection does not work and will need a lot of work

Which linux version supports this? 4.14, afaik, was broken

I tried to force it in dt, setting it to dr_mode = "perepheral", but it still was not working

narmstrong: oh, it should work as long as it's forced ? but I remember seeing it marked as not supported on the wiki :(
<xdarklight>
tingoose: you may have to check the kernel log, I believe you need to pass some of the g-* properties (which are only used in device/peripheral/gadget mode)
<xdarklight>
rtp: OTG (switching between host / device mode) is definitely not supported, but as narmstrong said forcing the controller into device mode might work
<tingoose>
yep, I've passed all necessary properties. Or is there any new properties that were introduced to g_ether since 3.16?
<tingoose>
Hm. Do you have any advice about exact numbers?
<gab>
tingoose: if it's any help, I managed to have it working on gxm with amlogic kernel 4.9
<gab>
(haven't tried it on mainline yet)
<xdarklight>
tingoose: unfortunately I have no advice on these numbers on GXBB - my best hint is to check Amlogic's GPL kernel sources or a kernel log from the Amlogic kernel
<tingoose>
Seems like there were a problem with auto-detection of this parameters

Seems like there were a problem with auto-detection of this parameters in dwc code
