Hello there!
I’m sorry to hear about the trouble with your Colibri VF61 module. Let’s work through the recovery process together. You have two main options: using the serial recovery method via UART_A or the USB OTG method. Here’s how you can proceed:
Serial Recovery via UART_A
-
Check Connections:
- Connect your Colibri VF61 module to your development PC using UART_A on the Iris board. Ensure that hardware flow control with RTS/CTS signals is used. If RTS/CTS are not connected, you can bridge them, but using them is recommended.
-
Run the Recovery Utility:
- Use the
imx_uartutility, which is invoked by theupdate.shscript. If RTS/CTS are not connected, use the-nparameter to bypass flow control:./update.sh -n - This command will download U-Boot to the module’s memory and start it. After downloading, you should see a serial console, which you can access using a terminal application like
screenorminicom.
- Use the
-
Power Cycle the Module:
- Once the bootloader is running, power cycle the module to clear the “enter recovery mode” flag, as a simple reset will not suffice.
USB OTG Recovery
If you prefer using USB OTG, follow these steps:
-
Connect via USB OTG:
- Connect the USB OTG port of the module to your PC using the appropriate USB cable.
-
Enter Recovery Mode:
- Follow the specific steps for entering recovery mode using USB OTG, which may involve setting certain pins or using a specific utility.
-
Run the Recovery Process:
- Use the appropriate tools and drivers on your PC to download and flash the bootloader via USB.
If you encounter any issues, double-check all connections and ensure that the correct parameters are used. This should help you successfully recover your Colibri VF61 module.
