Firmware update
Read this page carefully before starting update procedure and make sure all steps are clear for you
Update procedure requires use of USB-UART bridge and STM32 Flash loader demonstrator programm. You can download firmware from our repository. Update procedure is done as follows:
Turn off the robot and pull out its battery.
Connect USB-UART bridge to the ST-UPDT connector on the mainboard (its blue). Pay attention to proper connection of data pins - bridge's TX and RX pins should be connected to the RX and TX pins of motherboard accordingly.
3V3 pin of the ST-UPDT connector must be connected to 3.3V Volts source only! Connecting it to 5 Volts may result in device malfunction!
Set 4th group of DIP-switch to "ON" position
Connect USB-UART bridge to your PC, the system should recognize it as COM-port.
Press "HW_RESET" switch on the mainboard, this should lead to all the LEDs go out and mainboard turn into update mode.
Launch STM32 Flash loader demonstrator, choose your UART bridge COM port number. Press "Next".
