Unity Loader Firmware Password

[Kkalpoe]

I am trying to use unity loader to load a project file into an M580. I am connected via USB and when pressing connect, I am prompted to enter the firmware password. When I enter "fwdownload" I get an incorrect password notification.

But in control expert, when I set up firmware password protection, I am able to reset the password to the default "fwdownload" using... "fwdownload". I then build the project, load it to the M580.

But unity loader still tells me the password is incorrect when I try to use it to load the project.

Steps to Resolve the Unity Loader Firmware Password Issue

1) Double-check the password protection settings in Control Expert:
- Go to Project Settings > Protection > Firmware Download Password.
- Ensure the password is explicitly set to "fwdownload" (case-sensitive).
- Rebuild and download the project again to the M580.

2) Use the correct login credentials in Unity Loader:
- When prompted, make sure:
Username: loader
Password: the exact firmware password you set in Control Expert (e.g., fwdownload),

3) Try connecting via Ethernet instead of USB:
- Some users have reported that USB connections can behave inconsistently with password prompts.
- If possible, try using the Ethernet port and see if the password is accepted.

4) Check Unity Loader version compatibility:
- Ensure you're using Unity Loader v10 or higher, as earlier versions may not support the firmware password feature properly.

5) Clear cached credentials:
- Unity Loader may cache incorrect credentials. Try:
Restarting Unity Loader.
Rebooting the PC.
Reconnecting the USB or Ethernet cable.

Hello,

Please check the current firmware of your M580. If the firmware is v4.x, you cannot use Unity Loader.
