DJI Phantom 2 Vision+ Vision Plus Blank or Black Screen Repair and Fix
Section 2: Flashing procedure stage 2
- Now, flash the boot loader part of the NAND... Plug the TTL serial converter into a USB port on your computer
- Plug the TTL serial converter into a USB port on your computer
- Determine what COM port the device is assigned (https://tnp.uservoice.com/knowledgebase/articles/172101-determining-the-com-port-of-a-usb-to-serial-adapte )
- Open up Tera Term or similar terminal application, connect to the TTL serial converter by selecting the serial connection
- In Tera Term you goto Setup menu > Serial Port ...
- Choose the correct COM port that was assigned to your adapter, and choose "no flow control" and 115200 for the COM port speed
- Jumper BOOT and 3V3 pads of the wifi module PC board
- Connect the board to the TTL Serial adapter
- Note: I had some issues with the board not booting and the terminal program not displaying text from the board if I didn't connect specifically in this order: TTL adapter to USB port, then open Tera Term on the correct serial port, then connect the PC board to the TTL serial adapter (ie power the board)
- If you did everything correctly you'll see "BOOT ME BOOT ME BOOT ME" start displaying in the terminal window
- Now leave everything connected and close out Tera Term
- Open a Command Prompt and navigate to the folder where you put the Flash utility and binaries for phantom 2 vision plus wifi module firmware
- Execute this command: sfh_DM36x.exe -nandflash -v -p "COMXX" ubl1_editedByGaucho.img u-boot_modifiedByGaucho.img
- Note: replace "COMXX" with "COM3" if your device is on COM port #3. Quotes around COM are fine in the command
- It will start flashing some stuff and likely pop out and start saying "BOOT ME BOOT ME BOOT ME" again. At this point I hit CTRL-C which exits the utility. From there I kicked off the same command you see in step 9, above. Eventually all the flashing will succeed and you'll see something like this:
Note: if you don't see :Operation Completed Successfully" then you need to get the device to get into the "BOOT ME" loop again and run the script again (steps 5-9)
