[yari0757]

Hi,
I am installing Nicla Sense Me as shiled on Portenta h7. when i press reset button on board or using NVM_reset function or even using WatchDog timer, the H7 board not boot again,until i remove Nicla board from H7.
Also i have mentioned that when restart happen, the board not recognize by Arduino IDE, until i remove USB-C and plug-in it again.
I followed this link 1 for plug the Nicla on top H7 for pins and the communication between board is OK and every thing is working great.
