My steps
Load blink into arduino ide. Select leonardo. The Leo usb won't appear yet/still.
press Arduino reset button. Leo usb port will momentarily appear. Select it quickly and try to upload. But by the time blink is compiled, it can't upload because the usb has disappeared again. Persevere.
Using the same setup as your first (failed) attempt, click upload again. Wait until the compiler has almost finished, then press arduino reset button again. Just as the ide starts to try and upload, your Leo usb port momentarily reappears again, long enough for the upload to succeed.
Your Leo port will now appear in the dropdown menu again! Permanently...until the next time - You Reply: I cannot connect to Leonardo to upload sketches. I have tried reinstalling drivers and am told I have the latest drivers already installed. I can work around it using an external arduino connected via USB but that kind of defeats the whole point of lattepanda. Very disappointed. I have searched all that google has to offer, and these forums, but no solutions have worked for me. I am sure there is an easy fix,
I just can't find it. - You Reply: When I hit the arduino reset button, the blue lights flash and blink.
Prior to reset, device manager shows two greyed out USBs, one labeled USB7 Leonardo, the other USB8 Leonardo bootloader. Both only show if I change "view" to show hidden devices.
Upon reset, the USB 8 Leonardo bootloader momentarily turns black but at the end of the recycle returns to grey. - You Reply: I went to https://github.com/LattePandaTeam/Latte ... 0-Software and downloaded the 4G64GB driver set.
I applied the contents of the UART folder and received the message back that for Leonardo USB 7 the best driver was already installed.
Is there another package that I am missing? Some of the other folders have labels eg GNSS that are unknown to me.
Thanks
