I don’t think that this is actually a problem with RKI as I have built it from the unchanged git repository in case there was a problem with my build mechanism in Eclipse and it behaves in the same way. I am not getting anything on the terminal. I think that the problem is probably with the serial terminal setup, but I just wondered if anyone could rule out for me that it is an issue with the Model A board? I don’t think it can be memory as the linker script only defines 128Mb of RAM anyway. The lack of networking hardware should not be an issue as networking is disabled by default in RKI, but it would be helpful I anyone could tell me that they have run RKI on a Model A!</div><div> </div><div>I am using a Model A as the lower weight and power consumption make it a better choice than the Model B for installation on a model aircraft!</div><div> </div><div>Probably more usefully, could anyone advise me on debugging a serial terminal connection to the Pi?

Your project sounds neat, I would love to find out more about your
avionics board. Let me know if you make any progress with the I2C
on the Raspberry Pi, I was going to tackle that when I get some
free time.<br>

<div>Thanks for that Chris, using this build set gave me working
a compiler. I hadn't been able to get RTEMS source Builder to
work on Windows, but I didn’t try very hard as your build
set removed the need. I built the Raspberry Pi BSP and
all appears to be well.</div>
<div> </div>
<div>I am trying to get RKI to build, but this is early days.
I eventually need to use C++ and I like to use the Eclipse
IDE and so I have imported the source into Eclipse with a view
to getting the original C code to work, prior to porting it to
C++ as a base for my project. I am getting undefined
references in the link, but I can sort this out, I just need
to find which libraries are missing.</div>
<div> </div>
<div>The project I am working on is for a Raspberry Pi based
autopilot. I have designed an avionics board containing the
sensors. This board will interface to the Pi using I2C.
I had made a small and insignificant start to writing the
autopilot code, but it was a huge job! Linux is not suitable
for this kind of application and so I was going to use my own
microkernel. Doing this is insanely complicated however.
Using RTEMS will save me a huge amount of time as I can
concentrate on writing an autopilot and leave the details of
memory management, scheduling, etc. to a proven RTOS. Once
the autopilot code is in a suitable form, I will be making it,
along with the avionics design, available under GPL. Any
RTEMS device drivers that I write for the generic Pi
peripherals, I will make available as soon as I am happy they
work so that they can be considered for inclusion in the BSP.</div>
<div> </div>
<div>Please don’t expect miracles. Although I have a lot of
experience with low level programming, most of it was a while
ago (early 90’s) and I have not used RTEMS before. Also, this
is very much a hobby and I do have a life!</div>

<br>
I just built a new ARM compiler for MinGW using the RSB on
FreeBSD using ...<br>
<br>
../source-builder/sb-set-builder --host=mingw32 --trace
--log=log_arm <br>
--prefix=/opt/rtems/4.11 --no-install --bset-tar-file
4.11/rtems-arm<br>
<br>
You can find the tar file with the binaries at ...<br>
<br>
<a title="http://www.rtems.org/ftp/pub/rtems/people/chrisj/source-builder/4.11/mingw32/" class="moz-txt-link-freetext" href="http://www.rtems.org/ftp/pub/rtems/people/chrisj/source-builder/4.11/mingw32/" target="_parent">http://www.rtems.org/ftp/pub/rtems/people/chrisj/source-builder/4.11/mingw32/</a><br>
<br>
I will add more architectures as they become available. These
tools <br>
contain all required patches and should work on RTEMS 4.11
master.<br>
<br>
Using autoconf and automake in MSYS may require 'mount
c:/opt/rtems/4.11 <br>
/opt/rtems/4.11" where "c:/opt/rtems/4.11" is the path to where
you <br>
unpacked the tar file. The tool such as arm-rtems4.11-as, <br>
arm-rtems4.11-gcc should be relocatable.<br>
<br>
