Crowpanel Advance 5 - USB port always busy
My CrowPanel Advance 5 boots up just fine into the demo program. My goal is to use the Elecrow pre-compiled MicroPython + LVGL environment for my own apps. However, I can't stop the demo program! The CrowPanel won't accept a download of a .py (or any) program because the USB port says it's always busy. I have used Thonny, VSCode, and Arduino IDE to try a download to no avail - "device is busy". Pressing Boot or Reset buttons in any combination does not work. Ctrl-C or the "stop" function in Thonny don't work either for the same reason - "device is busy". I can get to a blank screen if I hold down the Boot button and press/release the Reset button but the device is still busy! I must be missing something obvious because no one else seems to have this problem.
I know the cable and computer port (computer USB to CrowPanel USB-C power/communications) are good because I did reflash the entire CrowPanel v1.1 from .bin files (on GitHub) with no problem using the Reflashing tool and same connection. However, the "always busy" problem remains. What's is left to try?
