Hi Tran,
If you look into the app_start_light for example, the TRACE_START is defined as FALSE.
Look at the makefile.
# Define TRACE to use with DBG module
TRACE ?=1
ifeq ($(TRACE), 1)
CFLAGS += -DDBG_ENABLE
#Define to bump debug baud rate to 921600
#CFLAGS += -DDEBUG_921600
endif
At the begining, the c file has defined the next code.
#ifndef DEBUG_START_UP
#define TRACE_START FALSE
#else
#define TRACE_START TRUE
#endif
.
.
.
In this case, if you want to debug the applications, you should define as below.
CFLAGS += -DDEBUG_START_UP
Please let me know if you have issues with the log print.
Regards,
Mario
