I plug a Hobbywing Skywalker ESC 60A to work with Matek F405 wing and it’s not ‘keep’ the calibration. It calibrate only if i plug the USB cable to Matek with 5v and then working properly but when i’m trying to plud without the USB 5V power then start beeping again with no calibration,so it look like ‘‘lose’’ it. Any ideas what happened with this ESC?
Solved. It’s matter of Matek bootloader.
