Hi Karl, if you want to test it, here are the missing pieces roughly explained: - I used kmod-usb-gadget-eth and kmod-usb-gadget-serial I know that there is another (older?) kernel module which also provides a network and console interface at the same time, but this must be configured via kernel command line parameter if I understand correctly so I've chosen to test this configfs approach - add a line to inittab like this: ttyGS0::askfirst:/usr/libexec/login.sh - patch /etc/hotplug.json on your device like this:
diff --git a/package/system/procd/files/hotplug.json b/package/system/procd/ files/hotplug.json index 1c949bbea3..25806637cc 100644 --- a/package/system/procd/files/hotplug.json +++ b/package/system/procd/files/hotplug.json @@ -33,6 +33,10 @@ [ "load-firmware", "/lib/firmware" ], [ "return" ] ] + ], + [ "if", + [ "regex", "DEVNAME", "^tty[A-Za-z0-9]" ], + [ "start-console", "%DEVNAME%" ] ] ], "remove" : [ - I used a shell script found at http://irq5.io/2016/12/22/raspberry-pi-zero-as-multiple-usb-gadgets/ to configure the gadget I'll send a patch for hotplug.json after I got some feedback for this procd stuff or better - in case this is merged, because otherwise we have a dependency issue otherwise... Another point on my list is auto-mounting of configfs to the right place. I'm feeling that this should not be part of the shell script but be done at a central place - still unsure where to put it because configfs is an optional kernel module and thus available later during boot...
