printf with openocd on makefile project
I had to remove the nosys flags. My makefile looks now like this and compiles:
# libraries LIBS = -lc -lm -lrdimon LIBDIR = LDFLAGS = $(MCU) -specs=nano.specs -specs=rdimon.specs -T$(LDSCRIPT) $(LIBDIR) $(LIBS) -Wl,-Map=$(BUILD_DIR)/$(TARGET).map,--cref -Wl,--gc-sections
I loaded the code on the STM32F031C6 (STEVAL-PTOOL1V1) and it works. I check the TX pins I have set manually (PB6 for TX and PB7 for RX) and I can see the UART frame. However, nothing is shown on my opencd server terminal when I call printf. I’m not prettu sure if the problem is t the st link Im using. I’m using a ST Link MB1440B which I have updated with the right FW as described in its docs. Then I connect TX and RX to CN9 pins but still not getting anything on the terminal... what am I missing?
