Farmduino 1.5V – Communication Issues, Firmware Flashing Failure, and Arduino IDE Upload Problem

[cumaali]

Hello everyone,

I hope you are all doing well. I am having several problems with a Farmduino 1.5V board that I produced using the PCB documents shared earlier. I would be very grateful if anyone could help or share their experience.

• I flashed the hex file after modifying the definition to identify the board as Farmduino V30.
• I programmed the 16U2 following this forum guide:
  Farmduino 2.0 bringup - #6 by jan.janson
• Then I programmed the STM32 using the 1.0.1 release from GitHub.
  After completing the steps above, I started receiving continuous messages like the ones below:14:56:15.978 → R81 XA1 XB1 YA1 YB1 ZA1 ZB1 Q0
  14:56:15.978 → R88 Q0
  14:56:16.491 → R00 Q0
  14:56:16.491 → R82 X0.00 Y0.00 Z0.00 Q0
  14:56:16.491 → R84 X0.00 Y0.00 Z0.00 Q0
  14:56:16.491 → R85 X-1 Y-1 Z-1 Q0

I connected an RPi4 running Genesis 1.8 OS to the Farmduino.
However, on the web app, the Raspberry Pi → Farmduino connection always appears disconnected.
When I try to flash the firmware from the FarmBot web interface, it fails every time.
I also tried to upload the Blink example to the Arduino Mega (via the 16U2 USB interface), but this was also unsuccessful.

Hey again, I fixed the problem with properly programming 16u2 fuses. And, Famduino connected to the Rpi4 successfully. HOWEVER, although peripherals connect properly, the motor drivers are not working properly. When I send the motor command on the Web to the Farmbot, the motor LED is not lighting and the motor does not run. Also, there is no activity 2 between 2560 and TI motor driver.

the motor LED is not lighting and the motor does not run

The motor LED is ON for each Step pulse. What does the serial conversation look like ?
