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:
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?

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.
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.
