Error opening SerialUSB after uploading code with rtc.begin

[simon88]

Hi all,

I encouter a bug when I try to use RTCZero library with a personnal board build with an atsmad21e18a and Vscode. In my setup I initialise my rtc like this rtc.begin(), I upload my code everything works, but if I try to reupload another code after some changes for example I can't, because in vscode at left bottom I'am always in Arduino uploading....
It's seem to have a problem with SerialUSB, because when I use rtc Vscode can't reopen serial console. If I comment rtc.begin() I have no problem at all.
