Can not build "FatFs_uSD_RTOS" for STM32F746G-Disco board?

Hi all,

I got this example "FatFs_uSD_RTOS" from the STM32cubeIDE "Example Selector" after selecting the STM32F746G-Disco board. I haven't change anything in it and tried to build it but I get these errors (below). The instructions don't say that I have to do anything just to build the project. What Am I missing? Thanks.

Hello @Rodo ,

Could you please try this workaround :

 Go to Windows > Preferences
Open the tab Error Parsers into C/C++ > Build > Settings
Select GNU Linker Error Parser, double click on the pattern for the 1st severity Ignore
Changer :
(.*?):?(\(\.[^\s+]+\+.*\))?:\s*(In function [`'"](.*)['"]:)
to :
(.*?):?(\(\.[^\s+]+\+.*\))?:\s*([Ii]n function [`'"](.*)['"]:)
