nRF52840_SteamVR_Bootloader

Just another dirty hack

How to build bootloader settings

• nrfutil.exe settings generate BootLoaderSettings.hex --family NRF52840 --application Application.hex --application-version 1619830293 --bootloader-version 1550036638 --bl-settings-version 1

What is needed to flash the chip

• nRFConnect
• SoftDevice.hex
• Bootloader.hex
• BootloaderSettings.hex
• Application.hex

About SteamVR Application

• 0x26000 - 0x5027F
• Modify 3C48A and 3C4A6, and you will get your own dongle firmware

Why build this?

• Fun
• Modify the application

Problems:

• Serial is not the same as the steamvr dongle application, so the nrfutil inside steamvr folder cann't be used.
