Hi Uwe!

Hmm... I guess your questions where answered, as I stated that the compile
went through perfectly.

The trap I ran into was simple and I started a discussion for it around 5
years ago...
I set up a project-l151 configuration and setup the system to use something

Then I found some technical issues on the module I used to test so I
brought it to the hardware guys. To do some further tests with NutO/S I
pulled my STM32 NUCLEO board, but it is a L152.
So I created a new project-l152 config and switched to

But I probably tested too many things in parallel and messed up uart.c in
Then the original module came back and I continued to write some lines of
testing code into the l151 (remember the 1 at the end!) but with loading
the project.conf the setup still keeps its settings to run in
After I found out, that editing -l151 doesn't help if the compiler runs in
-l152... Everything went perfectly. I just had to fix two lines in some
nut.conf file to get UART3 for beeing debug output. I will push that after
returning from holidays.

Finally that is the thing I requested 5 years ago: Why can't we add an
option to save the project path in the configuration (even optionally)?
I see that a normal standard project delivered with the package of NutO/S
should work with every configuration, but users of NutO/S do not stay at
using only the projects delivered with the system. They build projects on
top of the system. And I will probably have three different STM32 CPUs in
my next projects, so I have to switch not only the application, but the
complete library path with every project setting.

Kind regards
