Errors while building USB DWC OTG driver

[Deval Shah]

Also,

I compiled the same build for arm/realview_pbx_a9_qemu. And when I try this
on qemu using this command

#qemu-system-arm -no-reboot -nographic -M realview-pbx-a9 -m 256M -net none
-kernel sleep01.exe
pulseaudio: set_sink_input_volume() failed
pulseaudio: Reason: Invalid argument
pulseaudio: set_sink_input_mute() failed
pulseaudio: Reason: Invalid argument
nexus0: <RTEMS Nexus device>
#

The test comes out (of the loop ?) abruptly without performing its task.
i.e. sleep01 comes out without starting the slave threads or usb01 comes
out without opening the shell.

Next I did  this "objdump -t usb01.exe | grep bcm" and the output is below.

This shows that my driver is linked properly with the app testsuit right ?

Now for the debugging what are the methods with qemu? As in how to get step
by step analysis of the running program ?

Thank you,
