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

Hi if i try to re-install the firmware i get this error: please help, thank you

I have a problem i tried programming my Bittle pre configured, Board version 1.1 with https://ide.tinkergen.com/ with this routine : After this my robot emits the usual melody when switched on, but it starts to move its limbs in jerks and freezes, no longer recognising the input from the remote control and the phone, if I insert the serial board it emits a fixed sound. do I have to upload the firmware again? Or how can you help me? Thank you
