HELP! Didn't disconnect MOTORS doing firmware update


#1

HELP!!!

I was doing the firmware update for my new GOPIGO, and I saw the instruction to disconnect the motors.
I thought I might click OK first, then do the disconnect. Unfortunately, after I click OK, the process kept going without asking yes or no, then the firmware update was done quickly.

I reboot, then the demo program cannot find GOPIGO. Was the hardware damaged already? (cry…)

I am from China, it took me 10 days to wait for the kit to arrive from U.S… SO sad this happend…

What should I do now?


#2

Update:

I searched for solutions, and tried the instruction from one post After Firmware update, one motor runs constantly on reboot,

I tried sudo bash firmware_update_v16.sh, and it seemed works. Gopigo is moving forward again~~

To make sure it’s really good now, I did the troubleshoot,

can anyone help check my latest log to see if anything is wrong now?

@zhanghewnn,
It looks like the GoPiGo hardware is still working properly,

Can you tell us which image are you using on the SD card. Is it Dexter Industries Raspbian for Robots or something else.

Can you also do a firmware update to your GoPiGo, by typing the following command on your terminal/command line (Do disconnect the motors before you start).

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

Once you have done your firmware update, you should have all your programs working.

Can you try it out and let us know if this helps. If this doesn’t help, can you post the output of the firmware update and send another troubleshooting log.


#4

I think this problem could have been avoided. When you update the firmware it should say in bold letters that you must disconnect the motors before clicking OK. Like this: DISCONNECT MOTORS before clicking ok Also what if the update code ran the motors and if it got feedback from the motors then it would say you need to disconnect the motors before updating.

This could avoid mistakes like @zhanghewnn made.

Hi @graykevinb,

First of all, thank you for support :slight_smile: .
I’m taking a look in the firmware_update.sh and I see we already have those bold statements.

Take a look at firmware_update.sh - link.

Thank you!
