Make sure DFU driver has been installed. Check out "Install DFU Drivers" in this page
Connect the Receiver USB to computer while holding the boot button in.
- Select USB
- USB1 and click Refresh
- Connect
- select "Erasing & Programming"
- Tick all sectors and click "erase selected sectors"
- Browse firmware (hex or bin file) related to the hardware.
- Click "Start Programming"
- After programming, unplug USB and plug USB back in. If red LED blinks at 2Hz, the receiver is waiting for connecting with transmitter.
*** You can also flash it via INAV or BetaFlight configurator, load firmware local, just like flashing a flight crontroller.
Com / CLI Commands:
- Install serial_port_utility
- Firmware tx-matek-mr900-30-g431kb-default, USB = COM/CLI, connect USB directly to computer, install STM VCP driver, select STM32 COM port
- Firmware tx-matek-mr900-30-g431kb-siktelem, LT1/LR1 = COM/CLI, connect USB-TTL module to LT1/LR1, select USB-TTL COM port
