Hello,

I'm not sure if your request is tied somehow with the next one, please follow my reply there, too: 

X-CUBE-CLASSB-U5(STL) issue(Hardfault) of TM7 test... - STMicroelectronics Community

Anyway, pls verify if the TM7 test is executed from secured region at thread privilege mode and mainly if its execution can't be interrupted.

Best regards,

Petr

Hello,

status of your test is fully dependent on definitions of subsets at user structures and configured atomic steps. You can perform all the subsets at single run or per parts. Please study associated UG.

Best regards,
