@martinsky No problem - glad to hear it is now working..... the other two menus on my github page are also very good.... little more involved to setup, but worth the effort. The SD-Updater menu supports M5Stack library versions 0.1.6 and 0.1.7 (see notes under installation). The MultiApp Firmware Menu uses the ESP Flash Downloader to upload the code in place of the Arduino "IDE".
