Porting a Keil uVision project to the GNU tool chain

Hello Mohit,

our GNU expert is OOO this week and admittedly I dont have much experience of GNU myself. I did a quick search online : can .obj files be linked in GNU ? this thread belwo implies not.

Hi,

I ve got the same result, can not advertise when I compile with this toolchain gcc-arm-none-eabi-4_8-2014q3. However I can run come code (ie. led blinking) and its working.
我还可以确认UART驱动程序无法使用该工具链。我使用转换脚本来生成makefile。我也用DA14580_Beacon_3.40-2.6的样本代码进行了一些测试，没有运气。

无论我将CMD-> Channel_Map设置为零但零的任何东西，我似乎都崩溃了...

任何的想法 ？

I can confirm that -fplugin=tree_switch_shortcut_elf is not compatible with windows & mac version of gcc-arm-none-eabi-4_8-2014q3, but only on linux. I did not try on a linux box with with option (I'm compiling on a mac.)

Here is my Makefile for further info :

#makefile必须定义以下变量，该变量由common.mk使用：
＃O: output directory
＃stack_size：为堆栈保留的字节数

＃STARTUP_DEFS: define's that configure the start-up code
＃CFLAGS: flags used for compilation AND linking

I managed to compile with the 'tree_switch_elf' option using GCC 4.9 for mac,https://launchpad.net/gcc-arm-embedded/4.9. I make this change in the Makefile :

＃optimisation flags
cflags + = -os-ftree-switch-shortcut

在我使用cmd-> channel_map时，在模块上没有运气，在模块上相同的崩溃，选择一个广播频道..

Is there any chance to have an update on this project like having a full configured working project using the radio (including Makefile & updated linker script) using GNU GCC please ?

对这一主题的任何帮助都非常感谢！

谢谢:)

Hi,

Has there been any update yet?

阅读App Note B-024似乎暗示该项目构建和作品，有人有人遇到了与GCC工具链一起使用吗？

Thanks

The solution is to use this toolchain:
https://launchpad.net/gcc-arm-embedded/4.9/4.9-2015-q3-update
并将-fplugin = tree_switch_shortcut_ELF更改为-Ftree-Switch-快捷方式

可能您将获得关于__weak的下一个错误，通过添加-d__weak =“__属性__（（弱））”在compar中的cflags来解决。
And an error about __nop(), solve that by adding -D"__nop()"="asm(\"NOP\")"
