Before Using​

First of all, we need to reflash the USBDM itself, as there have been many bugs related to non-original or outdated firmware.

Common Errors​

USB Error​

  • Drivers: Necessary drivers may be outdated or missing.
  • USB Power: The device may not be receiving sufficient power.
  • USB Cable: Check the integrity and functionality of the USB cable.
  • Program Conflict: Two programs are trying to access the device simultaneously.

TargetNotConnected​

The programmer is connected, but the controller is not found.

  • Connection: Most often related to the connection to the controller.
  • Actions Inactive: Buttons are gray because the processor is not connected; we cannot perform any actions with it.
  • JTAG ID 0xFFFFFFF: This means that we attempted to connect via JTAG, but we have an empty line, i.e., the processor did not return any ID = not connected.
  • BDM Firmware: This error has a 20% chance of being caused by a counterfeit Chinese USBDM firmware, i.e., a 20% statistical likelihood.

That's it! You and USBDM are ready to work. Let’s go! 🚀
