Semihosting for the Blue Pill board (STM32F103C8T6) [SOLVED]

Posted by benkev on 2017-06-12 07:31

Hello!

The memo describing how to setup the semihosting in SW STM32 is in
C:\Ac6\SystemWorkbench\plugins\fr.ac6.mcu.documentation_1.2.0.201705091103\Advanced

It took me minutes to make the semihosting work. The text is very clear and very well illustrated, so I recommend it. There are other pieces of good documentation from Ac6 at
C:\Ac6\SystemWorkbench\plugins\fr.ac6.mcu.documentation_1.2.0.201705091103 :
CreateProject
ImportProject
Tips
BuildConf
Debug

However, I still do not understsnd if I can open an arbitrary file on the host’s hard drive and write to it from the target’s program, or I can only redirect stdout or/and stderr to the host? Would be nice if anybody explained.


I work in Windows 7. I am using SW STM32 Version: 2.0.1.201705161428.
I am trying to build a progect based on STM32F10x Standard Peripherals Library Drivers (StdPeriph_Driver), without STM32CubeMX.
The used hardware is (as was shown in one of the posts here):
The ST-Link v2 adapter:

The Blue Pill board:

Now one can buy it for $1.75.

There is a good, detailed description of the Blue Pill board, with great pinout and schematic at:

Hi,
I followed the instruction to enable semihosting by creating a basic project using cubeMx for a blue pill(STM32F103C8T6) with no success. semi hosting was effectively enabled (console output) but the printf triggers a hardFault_Handler ().
However, I tried the same instructions with 32F429IDISCOVERY board and the printf works fine on the openOSD console.
Any ideas ??
Thanks.
Atef
