Before I accidentally erase the emmc in vim2, I reinstalled os several times by using the usb upgrade mode. Therefore, I think it is not the problem of my PC. I have tried to connect my phone to pc with the usb cable that I used to connect vim2. Its works. I can access the file in my phone. Here are the details
Thank you for your help. Since my vim2 is not working, I have tried to use the both sides of the usb cable to connect my phone. I can access the file in my phone. Yes, I did installed this tool. When I tried to use the MRegister mode, I opened this tool. But the tool didn’t show me that it’s connected. And I have also checked in the Device Manager. Here’s the detail
The Mregister mode is not user-friendly. I follow all the instructions and tried many times(about 10 times), but its useless. I hope this problem can be solved and won’t be happen again. I think this Mregister mode should be replaces by another one, which is user-friendly.
If you just erase your VIM2, the VIM2 device should can boot into upgrade mode automately after powering on. If not, the issues may on PC side. Can you just uninstall and reinstall the upgrade tool and take a try? or just try with another computer?
If you VIM2 can still boot into u-boot, the Serial Mode should works for you if you are a devlopers and own a serial tool.
Hello, In the folder you installed the USB Burning Tool on your Windows PC, you will find a folder called, “World Cup Driver”. Inside that folder is an exe file to install the driver. It also has uninstall feature. Run the exe and uninstall the driver, restart PC. After reboot, run the World Cup exe again and select install driver, restart PC and see if VIM2 is recognized.
M-register may be required if boot loader or firmware become corrupted or I incorrect image is flashed to the VIM(2).
As to the USB Burning Tool, I have had to reinstall it a couple of times. I also have boxes with RK processors, they have their own burning tool. Often I have to reinstall the World Cup driver after using the RK tool. I don’t know why, some conflict I assume.
Glad you got it going.
