FAQ_MA35D1_Cross-Compiler Toolchain

[ytliu6]

Yocto and Buildroot both have their own cross-compile toolchain.

Build the Image first and the Buildroot toolchain will be generate at
/Buildroot/output/host/usr/bin/aarch64-nuvoton-linux-gnu-gcc

Refer to UM_MA35D1_Yocto for generating toolchain
After you source the toolchain, it will automatically include to the PATH.

This Makefile for uart_demo shows you how to set up the toolchain.
If you have source the Yocto toolchain, just remove the CC and STRIP, then compile.

Code: Select all

.SUFFIXES : .x .o .c .s

CC := ~/buildroot/MA35D1_Buildroot/output/host/usr/bin/aarch64-nuvoton-linux-gnu-gcc

STRIP := ~/buildroot/MA35D1_Buildroot/output/host/usr/bin/aarch64-nuvoton-linux-gnu-strip

TARGET = uart_demo
SRCS := uart.c
LIBS = -lpthread -lc -lgcc

all:
        $(CC) $(SRCS) -o $(TARGET) $(LIBS)
        $(STRIP) $(TARGET)

clean:
        rm -f *.o
        rm -f *.x
        rm -f *.flat
        rm -f *.map
        rm -f temp
        rm -f *.img
        rm -f $(TARGET)
        rm -f *.gdb
