<p class=MsoNormal><font size=2 face=Verdana><span style='font-size:10.0pt;
font-family:Verdana'>Hi Wendell,<br>
<br>
Thanks a lot for your information about VMWare. It increases my confidence
about VMWare. <br>
<br>
In your short message, you actually mentioned something interested to me. Using
Google translator, I briefly browsed COMPSIS website. With 19 years of history,
I guess COMPSIS is a big company with a lot of resource and is involved in
activities important to your country. </span></font><font size=2 face=Verdana><span
lang=EN-US style='font-size:10.0pt;font-family:Verdana'>I'm new to RTEMS, and
have very limited resource: just some spare time outside working hours and
limited personal funding, so I'll need a lot of help from RTEMS community on
various RTEMS issues down the road. <font color=navy><span style='color:navy'><o:p></o:p></span></font></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span lang=EN-US

<p class=MsoNormal><font size=2 face=Verdana><span lang=EN-US style='font-size:
10.0pt;font-family:Verdana'><br>
<br>
Limited available resource is one of the reasons I'm using VMWare now. </span></font><font
size=2 face=Verdana><span style='font-size:10.0pt;font-family:Verdana'>In the
past I abandoned some hardware (a waste to already limited funding), either
after finding out it's unsuitable or outdated due to the limited time I can
work on it. This time I hope using VMWare first can help me avoid some of such
costs. For example, like you mentioned about 2 UARTs, since I already use one
UART for remote debugging, I better select hardware kit with more than 2 UARTs
(for sensor interface). Now with Eclipse plug-in and GDB working in my
environment, I plan to shift focus to hardware part.<br>
<font color=navy><span style='color:navy'><o:p></o:p></span></font></span></font></p>
<p class=MsoNormal><font size=2 face=Verdana><span lang=EN-US style='font-size:
10.0pt;font-family:Verdana'><br>
Although RTEMS currently does not support the gigabit ethernet on the hardware
kit that I have in mind, I'm still interested in how you made GDB server
interface via TCP/IP work in RTEMS. </span></font><font size=2 face=Verdana><span
style='font-size:10.0pt;font-family:Verdana'>To my understanding, RTEMS is a
system with single process, and GDB server is another process, so how do you
launch GDB server in RTEMS?<br>
<br>
<font color=navy><span style='color:navy'><o:p></o:p></span></font></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span lang=EN-US
style='font-size:10.0pt;font-family:Arial;color:navy'>Robert, what we did was a
custom implementation of a GDB Server interface inside SIS (SPARC Instruction
Simulator) through a TCP/IP socket. So the RTEMS program (running on the SIS) is
not aware about this interface. RTEMS already has a glue code to implement the
GDB interface for some targets, including i386, but not for SPARC processors.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Verdana><span lang=EN-US style='font-size:
10.0pt;font-family:Verdana'> <br>
You also mentioned GPIO simulation with PC's parallel port. </span></font><font
size=2 face=Verdana><span style='font-size:10.0pt;font-family:Verdana'>For the
hardware kits I have in mind, some have 4-bit In/4-bit OUT GPIO, some don't. I
checked Discrete Driver chapter in RTEMS BSP and Device Driver Development
Guide. There are descriptions about the driver, but no concrete example code is
given. Do you know where I can find such a concrete example? Also in
c\src\lib\libbsp\i386\shared\comm\i386_io.h, there some macros like outp(port,
val) and inp(port) calling assembly code directly. May such macros be used to
access GPIO pins directly without using the discrete driver?<font color=navy><span
style='color:navy'><o:p></o:p></span></font></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span lang=EN-US
style='font-size:10.0pt;font-family:Arial;color:navy'>In the same way, we
implemented the GPIO code inside SIS. That is, when the RTEMS program access
the address of the GPIO registers it redirects such access to the PC’s parallel
port mapped through VMWare.</span></font><font size=2 face=Verdana><span
