Problem configuring ethernet interface for NFS in rtems-libbsd

[vivek kukreja]

Hello Sebastian,

The output of the qemu command is as follows:

Warning: nic cadence_gem.1 has no peer
nexus0: <RTEMS Nexus device>
zy7_slcr0: <Zynq-7000 slcr block> on nexus0
cgem0: <Cadence CGEM Gigabit Ethernet Interface> on nexus0

cgem0: cgem_mediachange: could not set ref clk0 to 25000000

I tried attaching the debug log file (partial) generated by using the
'-d exec' option but its too large (atleast 25 MB).

I debugged the code and found that control reaches till the
'rtems_bsd_program_call' function(under
rtems-libbsd/rtemsbsd/rtems/rtems-program.c) and stops at the
following step:

if (setjmp(prog_ctrl->return_context) == 0) {
  exit_code = (*prog)(context);
}

I think execution gets stuck at the assignment statement. I'm still
working on this and thank you for helping.

Regards,
Vivek
