Thanks a lot! I have one more stupid question. How do I run examples from
git? I've cloned rtems-examples and tried to follow the instructions from
"README.waf", but it doesn't work. When I enter
$ waf configure --rtems=$HOME/development/rtems/bsps/5 \
--rtems-tools=$HOME/development/rtems/5 \
--rtems-bsps=sparc/erc32
I get this error:
Command 'waf' not found, did you mean: ...
I probably do something wrong. Do I need to do the instructions from
"README.waf" at all? Or do I need to proceed as in this tutorial
https://docs.rtems.org/branches/master/user/start/app.html with every
example's directory? I would really appreciate some step-by-step
tutorial or instructions as I'm totally frustrated right now and don't
understand what to do.
Btw there is a makefile in every example's directory. Can I use it
instead of waf to compile the applications? If this is the case how do
I do it?
Many thanks in advance for any help!!!
