Tools and Information on how to flash Nolo VR Hardware manually

Tesseract-Cobra

This Project is a Collection of Tools, Firmware and Information and wasent authorized by LYRobotix/NOLO Co., Ltd.

Warning, i am not responsible if you do Brick your Device and make it unusable.

Please read all Instructions carefully.

Goal of this Project is to help Users of Nolo Hardware to flash their Hardware manually and without the usage of the Updaters. Its also our Target to make this Process as simple as possible, and to avoid bricking Hardware.

|-Warnings

• Do not manually flash your Device if you feel insecure about it or may not have the required Knowledge
• Be absolutly sure you do use the correct Firmware, only use Files from "/Firmware/Official/"
• Do not have multiply Nolo Devices connected at the same Time
• Use an proper USB Cable, having an loose Connection could interrupt the flashing Procedere and damage your Device
• If you have any further Questions, create an Issue or ask [email protected]

|-Flashing Manually

1. Lookup "Hardware Identifiers.txt" to find out your Hardware Model
2. Go to "/Drivers" and Install the ST32 Driver for CV1 Pre-Sale Devices or the GD32 Driver for regular CV1 Devices (idk about Nolo Home yet, propably its GD32)
3. Bring your Device into DFU Mode, Information on how todo can be found in "Enter Recovery and DFU-Mode.md"
4. Go to "/Tools" and go to "DfuSe" for flashing CV1 Pre-Sale Devices and "GD32" for regular CV1 Devices (idk about Nolo Home yet, propably its GD32)
5. A: For ST32, open up "/Bin/DfuSeDemo.exe"
   B: For GD32, Open up "GD32 MCU Dfu Tool.exe"
6. A: For ST32, select the Device in the upper Drop-Down Menu. If you see more then one Device, unplug your Hardware to find out which Device to use. Some Bluetooth Adapters are always in DFU mode, you may temporary disable them in the Device Manager.
   B: For GD32, click "No" when the Software asks for an Update. Select the Device in the upper Drop-Down Menu. If you see more then one Device, unplug your Hardware to find out which Device to use. Some Bluetooth Adapters are always in DFU mode, you may temporary disable them in the Device Manager
7. Download the required Firmware coresponding to your Device from "/Firmware/Official"
8. A: For ST32, click on "Choose..." in the "Upgrade or Verify Action" Section >Picture<. Navigate to the previously downloaded Firmware and select it. Click "Upgrade" to start the flashing Procedure, do not disconnect the Device now!
   B: For GD32, change the starting Adress in the "Download APP program file" Section, from 8000000 to 8003000 >Picture<. Click on "open" >Picture<. In the Lower right, select "BIN Files" >Picture<. Navigate to the previously downloaded Firmware and select it. Click "OK" in the lower right to start the flashing Procedure, do not disconnect the Device now!

Check firmware version

Hi,

I bought second set of nolo and forgot how I checked in the past firmware version under linux. I can do it from a Windows if you don't have idea. Previous one used v2.x, so was unable to use it under Linux with OSVR.
This one is non-retail, detached from Deepoon Headset by someone.

I will post data from lsusb and dmesg I gathered below:

ST32 Driver won't install [Windows 10]

When I try to install the ST32 driver in Win10 the installer fails.

It says: "Errors were encountered while installing the software for your devices. See the Status column for more details.

Sometimes it helps to run this wizard again. If that doesn't work, contact your device vendor"

The only information in the Status column is the text "Install failed"

And I have tried running it again a few times, rebooting, etc.

Be careful with GD devices

The default download address in the GD DFU tool is 0x08000000. However, the correct starting address for the firmware bin file should be 0x08003000.
Using the default address to download the firmware will brick the device. If the original firmware is not backed beforehand, there will be no way to recover the device due to copy protection.

Help with dumping Nolo CV1 Pro

Thank you for making such an useful guide.
I have a Nolo CV1 Pro and I want to dump firmware from it, but I am having problems.
I installed GD32 driver from the repo, and newest from the manufacturer's website, tried GD32 MCU Dfu Tool from here and from the manufacturer but after connecting the device in recovery mode it doesn't appear on the dropdown, neither in PortHelper.
Did I miss an important step? Could the Nolo driver be interfering?
This is the output on Linux of lsusb, maybe it will help?
