I can't get the chprintf to work. I'm on linux and downloaded ChibiStudio.
Managed to get it working, and compile, upload and debug a RT-STM32L432KC-NUCLEO32 demo, as this is the board I'm currently working on.
Unfortunately, when I added line below to the main thread:
Code: Select all
chprintf((BaseSequentialStream *)&SD2, 'Test: %d', 43);
...I got error:
"undefined reference to `chprintf'"
I tried adding #include <chprintf.h>, but this got me "fatal error: chprintf.h: No such file or directory"
Then I found this bug: https://sourceforge.net/p/chibios/bugs/567/
Tried adding "$(CHIBIOS)/os/hal/lib/streams/" to INCDIR. This solved the "No such file or directory issue", but the "undefined reference to chprintf" remained.
I'm scratching my head over this for two days now and thought that I'd ask for help here.
I'm probably missing something obvious - I'm noob in embedded OSes. Any guidance would be highly appreciated.
Below is my code before modyfing the Makefile. This one gives "fatal error: chprintf.h: No such file or directory"
Code: Select all
