STM32F215ZG with YAGARTO GNU ToolChain

I am now working on STM32F215ZG with YAGARTO GNU Toolchain, the YAGARTO version is showed below:

yagarto-bu-2.23.1_gcc-4.7.2-c-c++_nl-1.20.0_gdb-7.5.1_eabi_20121222;

yagarto-tools-20121018-setup.

the attachment is a demo project, it can be compiled OK by Keil MDK and also can be run OK on my board.

with YAGARTO ToolChain, it also can be compiled OK, but when i download the objective binary into my board, it can not work.

i don't know what happened, maybe the linker file (X600Boot.ld) or the startup_stm32f2xx.s file is wrong, or the makefile is wrong, anyone can help me?

#stm32-yagarto-gcc

Doesn't look bad from a cursory scan. Have you considered downloading/debugging the Yagarto output .ELF (aka AXF) with Keil?

Hi

As soon as I read your post it reminded me of similar problems that I had when first using the compiler. In the startup_stm32f2x.S file, I'm reasonably sure that the following call will be the culprit:

bl __libc_init_array

Since you're not using C++, it should be fine to comment out this line in the startup file.

Regards,

Carl.
