Good year!
Can anybody point me at a guide or set of notes for setting up a new BSP for
RTEMS 5, derived from an existing one, so that ‘configure’ will pick it up?
At one point I took Sebastian’s STM32H7 BSP and munged it to work with an F767,
but then the whole BSP system changed, my scripts broke, and I’ll have to start
again.
I need to know things like what directory to place my BSP, and how to get the
build system to recognize it.
I’m using the RTEMS User Manual 5.1 as my guide, targeting RTEMS 5 using MacOS
Mojave as a host.
I have the tools built and the script getting the kernel code is:
cd ~/RTEMS5/rtems
mkdir kernel
cd kernel
git clone git://git.rtems.org/rtems.git <git://git.rtems.org/rtems.git> rtems
cd rtems
git checkout 5
Then I patch in my stm32f767 BSP. I move:
configuration info into …/kernel/rtems/c/src/lib/libbsp/arm/stm32f767, stolen
from ../stm32f4 for now
code into …/kernel/rtems/bsp/arm/stm32f767, stolen from ../stm32f4 for now
and the script for building the kernel is
cd ~/RTEMS5/rtems/kernel/rtems
./bootstrap -c && ~/RTEMS5/rtems/rsb/source-builder/sb-bootstrap
cd ..
mkdir stm32f4
cd stm32f4
$HOME/RTEMS5/rtems/kernel/rtems/configure --prefix=$HOME/RTEMS5/rtems/5 \
--target=arm-rtems5 --enable-rtemsbsp=stm32f4 --enable-posix \
--disable-networking
make -j10 all
Building for stm32f4 builds clean.
Then I altered the script above swapping stm32f767 for stm32f4 and I get:
...
rm -f make/stm32f767.cache
make -f /Users/andreichichak/RTEMS5/rtems/kernel/rtems/c/src/make/bsp.mak \
'RTEMS_BSP=stm32f767' 'RTEMS_ROOT=.' \
