uClinux AddApp User Guide for lumit4510 : 说明： 如何给 uClinux 添加自己的应用程序 ------------------------------------------------------------------------- 可参考： http://www.ucdragon.com/bbs/printpage.asp?BoardID=1&id=106 为4510B添加自己程序 Step 1 : 1. cd uClinux-dist 2. cd user 3. mkdir myapp 4. cd myapp 5. vi demo.c #include #include int main(void) { printf("Hello world! \n"); printf("[lumit] - let us make it together \n"); printf("--------------------\n"); printf("http://www.lumit.org\n"); return 0; } 6. vi Makefile EXEC = demo OBJS = demo.o all: $(EXEC) $(EXEC): $(OBJS) $(CC) $(LDFLAGS) -o $@ $(OBJS) $(LDLIBS) romfs: $(ROMFSINST) /bin/$(EXEC) clean: rm -f $(EXEC) *.elf *.gdb *.o 7. vi uClinux-dist/user/Makefile 添加一行 dir_$(CONFIG_USER_MYAPP_DEMO) += myapp 309 # add by liming 310 dir_$(CONFIG_USER_MYAPP_DEMO) += myapp 311 8. vi uClinux-dist/Config/config.in 增添以下内容到文件最后 ############################################################################# mainmenu_option next_comment comment 'My New Application' bool 'demo' CONFIG_USER_MYAPP_DEMO bool 'app1' CONFIG_USER_MYAPP_APP1 bool 'app2' CONFIG_USER_MYAPP_APP2 bool 'app3' CONFIG_USER_MYAPP_APP3 comment "My New Application" endmenu ############################################################################# 9. 进行重新编译内核和文件系统的步骤 make dep make clean make lib_only (可以仅1次，不必要每次都来) make user_only (每次修改过您的应用程序之后，这一步后面的都必须重来) make romfs make image make 注意，如果前面已经编译成功过一次，那么后面只需进行 make user_only; make romfs; make 10. 下载内核，运行看看： \>load No begin address for download, use default address 0x8000 Mini TFTP Server 1.0 (IP : 192.168.168.101 PORT: 69) Load image file from host Type tftp -i 192.168.168.101 put filename at the host PC Press ESC key to exit Starting the TFTP download... ................................................
