System Workbench for STM32

@ tarek bouchkati

since in filesystem of my Windows 7 working station I have two (identical) copies of syscalls.c

1.
C:\Users\zaffing\Downloads\eclipse\plugins\com.st.microxplorer.rcp_4.16.0.201607131424\db\plugins\projectmanager\src\syscalls.c

2.
C:\Users\zaffing\Downloads\eclipse\plugins\fr.ac6.mcu.firmware_1.10.0.201607251855\resources\builtin\syscalls.c

I would like to ask:

"Do You suggest to modify one of those and recompile the project?"

"Which one?"(Ok I can try each of them)

"Is it possible to cover _write definition in syscalls.c with a redefined int _write(int file, char *ptr, int len) body somewhere else?"

"Can You (or anybody) explain more or rephrase the soldiering thing on 'Solder Bridge' SB10 (SWO) ? Is it something specific of a particular board? Which board? And what about other boards?"

Thank You.
