In order to flash the bootloader to a microcontroller, you first have to set


  		




  172
  
  
    
full read and write permissions to the USB ports of your system. You can do so


  		




  173
  
  
    
by executing the following command:


  		




  174
  
  
    
  >$ sudo echo 'KERNEL=="ttyUSB[0-9]*",NAME="tts/USB%n",SYMLINK+="%k",MODE="0666"' > /etc/udev/rules.d/50-ttyusb.rules


  		




  
  172
  
    
full read and write permissions to the USB ports of your system. To do so, first


  		




  
  173
  
    
create a new file by executing the following command:


  		




  
  174
  
    
  >$ sudo touch /etc/udev/rules.d/50-usb-serial.rules


  		




  
  175
  
    
Open the file in a text editor of your choice (sudo required) and add the lines:


  		




  
  176
  
    

  		




  
  177
  
    
  # Future Technology Devices International Ltd. - TTL-232RG


  		




  
  178
  
    
  SUBSYSTEMS=="usb", ACTION=="add", KERNEL=="ttyUSB[0-9]*",


  		




  
  179
  
    
  ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", MODE="0666"


  		




  
  180
  
    

  		




  
  181
  
    
  # Future Technology Devices International Ltd. - FT231X


  		




  
  182
  
    
  SUBSYSTEMS=="usb", ACTION=="add", KERNEL=="ttyUSB[0-9]*",


  		




  
  183
  
    
  ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6015", MODE="0666"


  		




  
  184
  
    

  		




  175
  185
  
    
Now connect the module you want to flash directly to your system (note that


  		




  176
  186
  
    
indirect flashing is not possible for the bootloader itself) and run the command


  		




  177
  187
  
    
  >$ make flash


  		




  178

If the procedure was not successful, the following hints might help:


  		




  
  189
  
    
  - Did your system apply the new rules?


  		




  
  190
  
    
    Reboot and try again!


  		




  179
  191
  
    
  - Could the makefile execute the stm32flash tool?


  		




  
  192
  
    
    Reinitialize the submodule and try again!


  		




  180
  193
  
    
  - Are the permissions for USB ports set correctly?


  		




  
  194
  
    
    Check the udev rules!


  		




  181
  195
  
    
  - Are there any other applications using the serial connection?


  		




  
  196
  
    
    Close any other applications using the serial connection!


  		




  182
  197
  
    
  - Is the AMiRo module connected to your system?


  		




  
  198
  
    
    Use the programming cable to connect the module to your system.


  		




  183
  199
  
    
  - Is the AMiRo module powered up?


  		




  
  200
  
    
    Keep a charger plugged in during flashing.


  		




  184
  201
  
    

  		




  185
  202
  
    
ATTENTION:


  		




  186
  203
  
    
Never flash a bootloader to the wrong module! Doing so might cause severe errors
