Good Morning,
I seem to be having an issue with RTEMS 5.1 Release Libbsd networking when I
include my own 'rtems_bsd_get_mac_address' function as described in
rtemsbsd/include/rtems/bsd/bsd.h. I'm running on a Xilinx Microzed using
xilinx_zynq_zedboard BSP and have a minimal RTEMS console application (source
code included below). The rc.conf file configures the cgem0 interface and
starts FTP and telnet daemons.
If I include the 'rtems_bsd_get_mac_address' function, the mac address is set
but RTEMS doesn't respond to any pings and doesn't allow any connections.
However, a ping to an external device from RTEMS is successful. I have run
tcpdump filtering on ICMP messages and RTEMS sees them.
If I comment out the 'rtems_bsd_get_mac_address' function, it has the default
mac address and everything works as expected.
All guidance and help are greatly appreciated.
Thanks,Rick
