Dear all,
I want to replace the tool-chain from ARMCC to GNU-GCC in the Windows Keil-ARM IDE.
Also I add the link script file which is offered from the ARM M0 SW package in the project. but I suffer a problem as below,
c:/program files (x86)/gnu arm embedded toolchain/9 2020-q2-update/bin/../lib/gcc/arm-none-eabi/9.3.1/../../../../arm-none-eabi/bin/ld.exe: ./startup_cmsdk_cm0.o: in function `Reset_Handler':E:\Mlink\project\medical\Project\toolchain_cp\medical1_svn109v3/cmsis/Device/ARM/CMSDK_CM0/Source/GCC/startup_CMSDK_CM0.s:199: undefined reference to `_start'
II found a article is related this problem, I follow the steps in this article, the problem is still the same. Also I have another question about this article.
IIn the step-2, it say "Enter the start address of the Text Section". How could I know the start address? Do I only assign a address within the code memory for start address?

Thank you for your advice.

Why?
If you take away the ARM toolchain, what does Keil actually give you ?
Why not just use a GCC-based toolchain in the first place?

Dear Andy,
Thanks for your reply. I want to try GNU-GCC in Keil-IDE, because
1. I have tried the GNU-GCC in Linux. It seems work, but the code size is larger than using the ARMCC in Keil-IDE. So I want to confirm it in Keil-IDE with GNU-GCC.
2.The code size of evaluation Keil-IDE is limited in 32KB. If I replace the ARMCC with GNU-GCC, is it still limited in 32KB?
Thanks for your advice.

Why would the IDE make any difference? It is the same compiler.

I guess not for compiling - but, if the debugger still works at all, that is still going to be limited.
Again, what would be the point of this? Why not just use a GCC-based IDE ?
Surely the only reason to use the Keil IDE is to get the ARM toolchain ?
