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
linking stage, driver is linked to testsuite (checked with objdump)

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!
