I’m having trouble connecting to my devices after the upgrade of Big Sur. I’m running Smart Development Bridge version 4.2.16. Whenever I try to connect via 'sdb connect ’ I get: error: failed to connect to remote target ‘’. This used to be working fine before the upgrade.
Open a developer support request and give them all the usual information, Tizen Studio and Mac OS version. They can contact the Tizen Studio Development team. It may be something new with the latest update.
