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-libbsd and cherry-picked Yurii's commits. While building libbsd using 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. -------------------------------------------------------------------------------------------------------------------------- In file included from /home/gadgetman/development/rtems/rtems-libbsd/testsuite/include/rtems/bsd/test/default-network-init.h:295:0, from ../../testsuite/arphole/test_main.c:118: /home/gadgetman/development/rtems/rtems-libbsd/rtemsbsd/include/bsp/nexus-devices.h:154:40: error: redefinition of 'bcm283x_dwcotg_res' static const rtems_bsd_device_resource bcm283x_dwcotg_res[] = { ^~~~~~~~~~~~~~~~~~ In file included from ../../testsuite/arphole/test_main.c:57:0: /home/gadgetman/development/rtems/rtems-libbsd/rtemsbsd/include/bsp/nexus-devices.h:154:40: note: previous definition of 'bcm283x_dwcotg_res' was here static const rtems_bsd_device_resource bcm283x_dwcotg_res[] = { ^~~~~~~~~~~~~~~~~~ ... -------------------------------------------------------------------------------------------------------------------------- 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
