Unable to upload to Tinybee, Access is denied

[Wallnutts]

Hi, im unable to flash and upload to my tinybee board using usb C cable as it gives me the error below. Tiny bee does show up and is detected in device manager.

I can only update firmware through access point + esp3d interface using OTA update.

Any idea how to fix?

This is that the motherboard cannot connect to VScode, you can troubleshoot by doing the following:

1. Use the switching power supply to supply power to the motherboard
2. Do not open other software that can occupy the serial port on the computer
3. Check whether the com port is com6 in the computer device manager

1. Tried plugging 24v power input but same result
2. No other software is using my serial ports
3. Vscode detects the correct com port as checked in device manager

Restart the computer and try to connect several times but still can't connect?Try unplugging other wiring on the motherboard, including lcd, driver, enstop, etc.

你可以使用esp32量产工具进行擦除芯片数据，以挽救网络设置，程序的问题

@ForOfJaime try to delete the package all about esp32 in (pio home/platforms ) or (C:\Users\Administrator.platformio\packages) and rebuid your project

@ForOfJaime may be it is a err from hardware or serial driver。try download flash tool to clean the memory (https://www.espressif.com.cn/sites/default/files/tools/flash_download_tool_3.9.3.zip).and make true link the motherboard correctly。I have a similar Mistake before . But after reset memory everything is ok .I think （#ESPWIFI SUPPORT）is the cause of the problem
