Hello,

I am using KEIL uVision3 for programming and debugging my STM32F103-Controller. When I try to compile the Demo-Project "CORTEX_STM32F103_Keil" the compiler stops with the following message in the output-window:

port.c: Internal fault: [0xafc2db:400524]
port.c: Please contact your supplier.
Target not created

What could be the reason for this error?

(used compiler-version KEIL uVision3 V3.80; FreeRTOSV7.4.2)

Thanks!

No idea, and it is a long time since I have had uVision 3. This looks like a tools issue and I doubt Keil will want to support such an old version.

If I build it with uVision 4 then the output is as below:
