Hi,
I think before jumping right into my current problem it might be a good
idea to explain where I am coming from, as there might be other
solutions to my problem.
What I need is Xenomai running on a Raspberry Pi to operate Machine
Kit. This can be downloaded pre-compiled, which I did and it's running
fine. So, there shouldn't be any need for me to build Xenomai from
sources. The problem is that I need the touchscreen driver for the now
available official Raspberry Pi touchscreen. That was not in the build
I managed to get, as it was obviously compiled before the touchscreen
was available. Using a copy of the driver binary
(drivers/input/touchscreen/rpi-ft5406.ko) and re-building dependencies
made the
driver available but the load attempt failed with a message indicating
binary format incompatibilities. At this point I saw myself forced to
build the OS myself from sources. My goals was, once that worked to
include the driver source in the build and hopefully have myself a
functioning installation. BTW, I am trying to cross compile form an x86
machine running Ubuntu.
Now, I am not a Linux hot-shot and have never built a kernel before, so
things are a bit shaky. Though I did a good bit of studying on the
topic in recent weeks.
I think I have finally figured out all the things I need to download
and install. I also think I managed to generate a good build of the
basic Raspberry Pi. Perhaps I should try to install the image and see
if that is true, but I wanted to press on and try to get compiles to
function.
At this point I m trying to do step number 1, configure the patch for
Xenomai 3.0.1 with linux-rpi 4.1 using ipipe-core-4.1-arm-1.patch. As I
understand it, the patch number must match the release number of the
target core as closely as possible. So this should be the correct patch.
Below is the output captured from the console. As you can see it failed
to apply the patch. I can see two locations indicated where it failed.
At this point I am really at a loss as to what to do next. Any advise
would be greatly appreciated.
