"Error writing to GoPiGo (errno5)"


#1

Hi everyone!
I have a problem with my GoPiGo and I will try to explain as best I can.

The day before yesterday I was working with my GoPiGo reading and processing to the camera and sending signals to the motors to move and everything was just fine. But the next day (yesterday), testing the same code I did it doesn’t work, and not only that, any example program work.

I tried to run the ‘basic_test_all.c’, and trying to move the motors or the sensor it throws this error:
“Error writing to GoPiGo (errno5)”.

I watched the function of ‘gopigo.c’ that throws that error and is: int write_block(char cmd,char v1,char v2,char v3).

I tried to fix the error doing several things like:

  • Changing the position of the motor wires (white-black-white-black to others positions).

  • I checked it out all the connections at the GoPiGo and saw that everything is in place.

  • Reinstall the last firmware version of the GoPiGo.

I also execute the test of the GoPiGo and gave this ‘logs.txt’:

I don’t know what the mistake might be. I’m thinking that it could be a bad connection betwern the RaspberryPi - Arduino but everything is well connected.
I appreciate your time and your answers.

Hi @nachotorresguaita95,

Thanks a lot for sharing with us the logs. It looks like the firmware isn’t responding. Can you tell us how you did a firmware update also try running the following command from the terminal to do a firmware update:

sudo bash /home/pi/Desktop/GoPiGo/Firmware/firmware_update.sh

You can also refer to the firmware update script available here.

Please let us know if this helps,
-Shoban
