How to Upload Roboracer Alpha Mu firmware to Roboracer Alpha microcontroller Using xLoader for Windows PC
- Open xLoader
- Browse the HEX File from RoboracerAlphaMuTM folder. The file is called:- RoboracerAlphaMuTM.ino.hex
- Select the device E.g. In case of Arduino Uno, it's ATmega328
- Select COM Port
- Select right baud rate in case of Arduino Uno it's 115200
- Finally hit Upload Button
- Download and extract the contents of the zip file into your home directory.
- Install Avrdude
sudo apt-get install avrdude
- Make project folder in user home:
mkdir RoboracerAlphaMuTM
- Find your serial device (tty)
ls -l /dev/ttyUSB* && ls -l /dev/ttyS*
- The file is called:- RoboracerAlphaMuTM.ino.hex, make sure you provide the P parameter with the value for your serial device on your computer.
avrdude -v -p atmega328p -c arduino -P /dev/ttyUSB0 -b 57600 -D -U flash:w:/home/RoboracerAlphaMuTM/avrdude/RoboracerAlphaMuTM.ino.hex:i
You should get the following output:-
