Hello Deval,
where is this DWC OTG driver code? The driver must have the right
DRIVER_MODULE() and MODULE_DEPEND() definitions.

Hello,
Currently, I am working on porting USB DWC OTG driver on Raspberry Pi.
Last year Yurii Shevtsov worked on the same. So, I forked the latest
rtems-libbsdand cherry-picked Yurii's commits. While building
libbsdusing waf, I got the following error.
---------------------------------------------------------------------------------------------------------------------------
testsuite/arphole/test_main.c.17.o:(.rtemsroset.bsd.nexus.content+0x10):
undefined reference to `_bsd_bcm283x_dwcotg_nexusmodule_sys_init'
collect2: error: ld returned 1 exit status
...

This error is observed in all the testsuits which are related to
networing. Then according to this wiki
https://devel.rtems.org/wiki/GSoC/2015/RaspberryPiUSBSupport, I added
following lines to those testsuits.
-- #include <bsp/nexus-devices.h>
-- SYSINIT_NEED_USB_CORE;
-- SYSINIT_DRIVER_REFERENCE(bcm283x_dwcotg, nexus);
I get the following redefiation error this time.

Also, looks like the error is only in the testsuits. USB drivers are
compiled properly. What is another way to test the port ? Is there any
other testsuit available ? Are there any other standard methods to
evaluate this ?
Thanks in advance,
Deval Shah
