Linker Garbage Collection Notes in CubeIDE for Target MCU F767

[Chao]

Hi

Recently, when I import an LWIP example project from MDK to CubeIDE, I get the following note message::

     "note: the message above does not take linker garbage collection into account"

I have 2 questions against these notes:

1. Do these notes have any negative affects on generatiing correct binary of the project ?

2. If they don't have any negative affects, then how to avoid these annoying messages ?

Thanks

Chao

Hello @Chao 

I assume that this issue has been answered here: Solved: STM32CubeIDE 1.13.0 problem - Page 3 - STMicroelectronics Community "this is ‘just’ a warning, and the linker is able to generate a proper ELF file. As long as your application does not use read/write/close/lseek (which should be the case for a bare metal application), your application will run properly."

Thank you so much! I found the syscall.c is missing in my project.
