with assembly declear:
#ifdef STANDALONE #define USE_SERIAL_PORT 1 asm(".global __use_no_semihosting"); #endif
to exclude any c clib being linked to output file
but i get the error info as follows:
Error: L6915E: Library reports error: __use_no_semihosting was requested, but _sys_command_string was referenced.
the question is, target is aarch64 cortex-a53,
no choice for me to link micro lib
what should I do?
Hi againTry this instead. Into both makefiles for startup_Armv8-Ax1_AC6 and startup_Cortex-A53x1_AC6 add:APP_C_SRC := $(wildcard $(SRC_DIR)/*.c)EXT_C_SRC := $(wildcard $(SRC_DIR)/dirx/*.c)APP_S_SRC := $(wildcard $(ASM_DIR)/*.S)OBJ_FILES := $(APP_C_SRC:$(SRC_DIR)/%.c=$(OBJ_DIR)/%.o) \ $(EXT_C_SRC:$(SRC_DIR)/dirx/%.c=$(OBJ_DIR)/%.o) \ $(APP_S_SRC:$(ASM_DIR)/%.S=$(OBJ_DIR)/%.o)DEP_FILES := $(OBJ_FILES:%=%.d)and later add a compilation rule for the new folder, for startup_Armv8-Ax1_AC6:$(OBJ_DIR)/%.o : $(SRC_DIR)/dirx/%.c | $(OBJ_DIR) $(PROGRESS) $(QUIET) $(CC) -c $(TARGET_ARCH) $(CPPFLAGS) $(CFLAGS) -o $@ $<and (slightly different) for startup_Cortex-A53x1_AC6:$(OBJ_DIR)/%.o : $(SRC_DIR)/dirx/%.c | $(OBJ_DIR) $(PROGRESS) $(QUIET) $(CC) -c $(TARGET_CPU) $(CPPFLAGS) $(CFLAGS) -o $@ $<Hope this helpsStephen
