djjerdog Posted February 23, 2020 Share Posted February 23, 2020 Using Armbian_20.02.1 with 5.4 kernel on NEO2 board, I'm running into an issue trying to get the USB OTG working with the g_ether module. When I run modprobe g_ether I see the following in dmesg: [ 490.490582] udc-core: couldn't find an available UDC - added [g_ether] to list of pending drivers I've also tried compiling my own img using the Armbian builder but it looks like all the correct OTG options are already selected by default. Any ideas what I'm doing wrong? Link to comment Share on other sites More sharing options...
djjerdog Posted February 24, 2020 Author Share Posted February 24, 2020 Ok, I narrowed it down a bit, it appears this is specific to the NEO2 Black Armbian image, works fine if I use the NEO2 Armbian image (even on a NEO2 Black board). Using Armbian_20.02.1_Nanopineo2_buster_current_5.4.20 g_ether loads just fine [ 190.883225] g_ether gadget: Ethernet Gadget, version: Memorial Day 2008 [ 190.883234] g_ether gadget: g_ether ready [ 191.258813] g_ether gadget: high-speed config #1: CDC Ethernet (EEM) However, using Armbian_20.02.1_Nanopineo2black_buster_current_5.4.20 I see the following when I try to modprobe g_ether [ 490.490582] udc-core: couldn't find an available UDC - added [g_ether] to list of pending drivers Any ideas why g_ether works fine when using the Nanopineo2 image but not when using the Nanopineo2black image?

It works fine on Nanopineo2black image since yesterday. (tested) The reason for discrepancy is here. Neo2 uses different config / DT. 1 Link to comment Share on other sites More sharing options...

ravelo Posted July 5, 2020 Share Posted July 5, 2020 sorry, I do not understand if this question is an aswer or not.. Quote The one which you are supporting? Ok, I tend to understand that there is no such thing as a maintainer for ambian buster on tritium h5. So be it. I am willing to investigate and fix if I know how to, then publish the solution to the community. But to get started, I would need a small amout of info to know here to look at first.
