EVBHelper

EVBHelper is an Avalonia-based desktop utility that helps manage Allwinner evaluation boards. It offers a graphical workflow to flash firmware images through the rfel command-line tool and to run common FEL maintenance operations.

Highlights

• Configure the rfel executable path and choose the desired logging verbosity (-v, -vv, -vvv).
• Browse for firmware images, provide the load address, and optionally initialize DDR or reset the device after flashing.
• Run device checks, start flashing, trigger resets, or cancel long-running actions without leaving the GUI.
• Review a structured log pane with timestamped entries and quick status messages.

Prerequisites

• .NET SDK 10 (or newer with compatible target frameworks).
• The rfel command-line utility installed locally or available on PATH.
• Windows, Linux, or macOS desktop environment.

Getting Started

1. Clone the repository:

   git clone <repo-url>
   cd EVBHelper

2. Build the solution:

   dotnet build

3. Launch the desktop app:

   dotnet run --project EVBHelper/EVBHelper.csproj

4. Execute tests:

   dotnet test

Usage Tips

1. Provide the path to rfel (or simply type rfel if the executable is on PATH).
2. Select the firmware file, confirm the load address (for example 0x40008000), and enable optional steps like DDR initialization or automatic reset.
3. Click Check Device to confirm the board is in FEL mode.
4. Choose Start Flashing to write the image; monitor progress in the log view.
5. Use Cancel to stop the current operation or Clear Log to reset the output panel.

Troubleshooting

• rfel not found: Confirm the path is correct or update your PATH environment variable.
• Flash failures: Review the log entries, verify the board is in FEL mode, and double-check the load address and firmware image.
• DDR initialization issues: Try changing the profile value or disable the option and retry.
