Sebastian just added the pc386 to the nexus-devices file. Make sure
the bsp.h is tripping the conditional logic in that file to get the Pi
path as a minimum.
Then you are going to need to add the appropriate devices for Pi
USB. If the Pi doesn't have one of the standard USB controllers, then
you will have to import the source for it from FreeBSD.
The pc386 is stuck at the point where it detects the NIC configured
but needs resources. I am going to try to debug that.

So, it is empty.
.rtemsroset.bsd.nexus.begin
0x001104bc 0x0 ./libbsd.a(rtems-bsd-nexus.c.16.o)
0x001104bc _bsd__start_set_nexus
.rtemsroset.bsd.nexus.end
0x001104bc 0x0 ./libbsd.a(rtems-bsd-nexus.c.16.o)
0x001104bc _bsd__stop_set_nexus
What will be next step? My repo:

You can debug this issue on Qemu. The Nexus childes are registered in a
linker set, so I would consult the linker map file. It should look like
this:
.rtemsroset.bsd.nexus.begin
0x000000000052ef7c 0x0 libbsd.a(rtems-bsd-nexus.o)
0x000000000052ef7c _bsd__start_set_nexus
.rtemsroset.bsd.nexus.content
0x000000000052ef7c 0x28
testsuite/telnetd01/test_main.o
.rtemsroset.bsd.nexus.end
0x000000000052efa4 0x0 libbsd.a(rtems-bsd-nexus.o)
0x000000000052efa4 _bsd__stop_set_nexus
The .rtemsroset.bsd.nexus.content section must be non-empty.

Any ideas? Maybe I did some typo? Maybe you can compile and try it in
qemu?

I would set a break point to nexus_probe(). In this loop
SET_FOREACH(nd, nexus) {
device_add_child(dev, nd->name, nd->unit);
}
your device must get added. I would also set break points to the probe
and
attach functions of your device.
Added printfs()
printf("before setforeach\n");
SET_FOREACH(nd, nexus) {
printf("setforeach: %s\n", nd->name);
device_add_child(dev, nd->name, nd->unit);
}
Got only 'before setforeach' in console. So it doesn't step into loop.
Any ideas? Also I already had printfs in my driver's probe and attach,
also got no output.

This is ping message, with small update: the problem is not on the

Hello)
Now I have apps from libbsd testsuite running. But DWC OTG driver
doesn't
loads.
I added this lines to init01/test_main.c:
+SYSINIT_NEED_USB_CORE;
+SYSINIT_DRIVER_REFERENCE(bcm283x_dwcotg, nexus);
(I know it's bad hardcode)
If I run it. I get only this:
nexus0:<RTEMS Nexus device>
devctl: +nexus0 at on root0
devctl: !system=IFNET subsystem=lo0 type=ATTACH
Of course, I modified rtemsbsd/include/machine/rtems-bsd-sysinit.h and
rtemsbsd/include/bsp/nexus-devices.h (took vlues from working DTS) and
did other nexus-related changes to drivers. You can find changes in my
repo https://github.com/gtament/rtems-libbsd/
So I need some kind of code review, please.
P.S. All testsuites (netshell01, usb01) with shell hangs without any
output.
Thanks in advance!
