Hello All,
I am trying to set up a tcm_usb_gadget on a board with DWC3 UDC.
When targetcli deb package was installed, a bunch of messages
appeared, including this:
[....] Fabric module tcm_usb_gadget is not loaded ... (warning).
Any idea why is that?
Comparing startup and running configs...
Invalid fabric identifier 'usb_gadget': expected type 'loopback',
'iscsi', 'ib_srpt', 'vhost', 'tcm_fc', 'qla2xxx'
Why is 'usb_gadget' fabric unknown?
The gadget goes alive, I can list it on my Linux host, but I
repeatedly get:
[ 177.628876] g_target gadget: high-speed config #1: Linux Target
[ 177.633411] Using the BOT protocol
[ 198.459512] ERR bot_status_complete(64)

...
Any ideas, why?
I don't think the usb gadget fabric gets much use. There's no way to use
it or test it because a regular PC doesn't have the hardware to be a
downstream USB device.
Btw, it's possible to test using dummy_hcd.
Hi Guys,
Thanks for your responses.
Actually I've been into usb gadget for quite a long time now,
and for the purpose of the above tests I use dwc3 UDC/OTG
on an Odroid XU3 which is Exynos 5422 based. In other words
I want to test tcm on real hardware connected with a real
USB cable to a PC.
I will let you know if I am able to go any further with the fixes
from Nicholas.
Thanks,
Andrzej
