The .bin built by arm-none-eabi-gcc cannot execute on stm32f2xx

I built a stm32f2xx project with BSP and uCOS by arm-none-eabi-gcc on both windows and ubuntu. But both binaries cannot be executed on the board. I don't know what's wrong with it. The project can be built by Keil, and the binary can be executed on the board. Could anyone help me? Thank you very much!

I have no error in compiling and linking on Ubuntu. But the binary cannot be executed. Here is the makefile.

I met an error in linking on windows, undefined reference to _sbrk. So I add --specs=nosys.specs option in the linking step and add symbol "end" in the .ld file, the linking succeed. However, the binary cannot be executed. Here is the .bat file.
