Atollic TrueStudio "Invalid project path: Include path not found"



Warning in Atollic TrueStudio "Invalid project path: Include path not found"

Example below:


Invalid project path: Include path not found (C:\Program Files (x86)\Atollic\TrueSTUDIO for ARM Pro x.y.z\ARMTools\arm-atollic-eabi\include\c++\4.7.3)

Solve ARM GCC error "register may not be same – ‘strexb r3,r2,[r3]’"




This error arises because strexb and strexh is undefined when two registers are same. The problems would be in lines 736 and 753 of inc/core_support/core_cm3.c.
