Hi Albert, - By simultaneously pressing button 1 and reset (using on/off buttons) XDK device, it goes to bootloader mode. In bootloader mode you can see red and yellow led glowing. - Connect com port using teraterm, hterm or any other SWs - Issue a command i to read bootloader version and e to erase flash area and then disconnect com port from teraterm - In workbench select 'Window-> Preferences->XDK->Bootloader and FOTA' and provide your bootloader version. Ex : 1.2.0 - Now restart the XDK device, if com port detected in workbench , build valid application and flash it. Thank You 🙂
