Hi


If you do everything according to this description, you must succeed.
The condition is one, the driver for FTDI chip has to be installed correctly beforehand.
And, of course, don't forget to turn on the printer's power.

I can tell you something more.

• 1. turn off the power supply,

• 2. Connect the USB cable,

• 3. Put on the jumper cap,

• 4. Turn on the printer power supply,

• 5. observe LED D7 - must not be extinguished,
  You can read more about this here,

• 6. start the Flash Loader Demonstrator program,

• 7. Be sure to set the correct address for the input.

If you have mistaken address and uploaded the firmware instead of the bootloader, you don't have to worry.

Simply start with this step.

You may also try to describe your intensification in detail. Then we will know whether you have made a mistake somewhere.
For the time being, we only know that you have failed to perform this responsible operation correctly. But we do not know the cause of the failure.

I wish you success and perseverance.

Ok, i need to install the bootloader before firmware? Led D7 is on, its mean the bootloader is instaled?

Yes, the bootloader must be present for firmware programming to succeed.
An illuminated D7 LED indicates that the botloader should be active.

Of course, remember to remove the jumper cap after the programming process and reset the controller board.
