Question about TX_SAFETY_CRITICAL compile option

Question

In the tx_api.h header file, I found the compile option TX_SAFETY_CRITICAL.
However, I cannot find any documentation regarding this.
Where can I get the documentation?

From the source code, I ound that I cannot use the define TX_SAFETY_CRITICAL in combination with other defines, e.g. TX_ENABLE_STACK_CHECKING.
What is the reason for that?

Thanks and best regards, Katharina

Hi Katharina,

The safety critical documents are part of the certification package. See here for more information: https://techcommunity.microsoft.com/t5/internet-of-things-blog/building-iot-solutions-for-safety-critical-environments/ba-p/2420780

The stack checking code is an optional feature of ThreadX. To limit the number of processing paths for the certifications, we disallow some of these optional features from being used.
