Hi, I downloaded the latest firmware update, apparently I updated the Bittle but if I try to turn it on nothing happens, now I try to update again and I get this error, I lowered and changed com and the port speed, installed the drivers (ch341 serial) again but I haven't solved it, can you help me?
thank you


thank you, you were very kind, good work and have a good day ! Fabrizioif I press the reset button nothing happens, it doesn't produce any soundHI,
here is what was requestedPlease unplug and re-plug the USB port on the computer side after opening the Firmware Uploader interface to make sure to use the correct serial port. If it still can't upload the firmware, please copy(Press and hold the left button of the mouse to select the text, release the left button after selection, and then click the right button to complete the copy.) and paste the whole log in the console interface.
