Sorry for the late reply.
Please verify that the bootloader is running by checking if the onboard LED (Pin PB0) turns on?
Any chance it's related to this: https://github.com/Lauszus/Sanguino/issues/26#issuecomment-766091817
Hello,
I am trying to update the firmware of my Creality V1.1.4 board using Sanguino as an ATMEGA1284p board in Arduino. I've managed to burn a bootloader to the board, using an Arduino Uno, with programmer set as Arduino as ISP, and connecting the board to arduino via ICSP ports. The bootloader seems to upload fine (I already tried to reflash the bootloader multiple times, and all seems good in Arduino IDE).
However, when I try to upload the Firmware, it compiles fine, but it can't be uploaded to the board. These are the messages I get in arduino IDE:
I have tried multiple solutions. So far, the best change was to modify the boards.txt located in C:\\AppData\Local\Arduino15\packages\Sanguino\hardware\avr\1.0.3 with the following lines:
I tried the following baudrates: 9600, 19200, 38400, 57600, 74880, 115200 and 250000. None of them worked. I also tried a different USB port (when the board is connected, the COM port appears in device manager, so I don't think it is a port or a cable issue). I honestly don't know what else to try. Can you help me?
EDIT: I was able to upload the firmware using arduino uno as an ISP running as Sanguino. Still, I would like to fix the USB connection problem, since any change in firmware I wish to implement means I have to open the printer case in order to access the board.
