CAN Network Connection Recovery
Since you’ve successfully copied the flash data but lost CAN network connections, this suggests an issue with the module configuration block or registry settings. Here’s how to address this:
Restoring Factory Configuration
The issue you’re experiencing is likely related to the module’s factory configuration being corrupted or not properly restored (1). You’ll need to restore the factory information using the bootloader commands.
First, access the bootloader console by pressing SPACE during boot (1):
Press [SPACE] to enter Bootloader Menu
Then press X to access the command prompt (1).
Module Configuration Recovery
Each module has specific factory information that needs to be restored. Check the sticker on your module for the following format (1):
- Col type
- V version
- serial
Use the restorefactoryinfo command with your module’s information (1):
>restorefactoryinfo *modulecode* *serial* *ver*
For VF50 modules, the modulecode parameter should be either VF50128 or VF50128IT depending on your specific variant (1).
Example command format (1):
>restorefactoryinfo VF50128 04790168 1.0B
Registry Cleanup
If the CAN network is still not working after restoring factory info, you may need to clear the registry (1). This is important because registry settings from the old module might be incompatible:
- Boot the module and press SPACE to enter the bootloader menu (1)
- Press C to clear the registry (1)
Warning: After registry cleanup, you’ll need to reconfigure your display resolution, network settings, and other configurations (1).
Alternative Recovery Method
If the above doesn’t resolve the CAN issues, you might need to use the bootloader’s flash erasing capabilities (1):
- Access the bootloader command prompt
- Use the
eraseflash command to clear specific flash regions if needed (1)
- Restore the backup files using the Update Tool
USB-B and Ethernet Connectivity
Since you have USB-B and Ethernet ports available on your main board, you can use these for:
- USB-B: For connecting to a PC to run the Update Tool or access the bootloader console
- Ethernet: For network-based updates if properly connected to the Colibri module (2)
The Ethernet connectivity can be used for data transfer as documented in the Ethernet communication procedures (2), but you’ll need to verify that it’s properly connected to the Colibri module on your custom board.
Important Notes
- Make sure you’re using the latest Update Tool version, as older versions may not work properly for version changes (1)
- The VF50 module supports advanced power management and GPIO configuration through registry settings (3)
- If power loss occurs during programming, the flash could get corrupted, but as long as the bootloader isn’t damaged, recovery is possible (1)
Try the factory information restoration first, as this is the most likely cause of your CAN network connection issues after a module replacement.
