Just brought a BrickPi. Nothing seems to work at all.
First: there are no blue less on the board so cannot tell whether the LED test works or not.
Second, try to run the LEGO-Motor_Test.py. No motors were moving.
Cannot find any other diagnostic tool for BrickPi.
What should I do?
Sorry that it isn’t working. First what BrickPi are you using? Could you post a picture of it? You may be running the wrong code for the wrong version.
Also are you running Raspbian For Robots? If your using the sd card that/if came you are using raspbian for robots. If you are not using that operating system I highly recommend switching. Everything will all be setup and work nice.
On Raspbian For Robots there should be on the Desktop a shortcut that brings will run some debugging tests. Could you run that selecting BrickPi and post the output?
Also what do you mean by “blue less?” Do you mean there is no led on your board?
This is the BrickPi I use
I cannot find any blue LEDs on the circuit board ( my model looks to be different from the one used in some youtube video showing flashing LEDs )
I download Raspbian for Robots on an SD card using this link:
I try to run the python files under BrickPi+
After trying everything, I ran the DI Software Update and update Robot with the option BrickPi3. Later, I realised that my model is BrickPi.
My raspberry pi model is raspberry pi 3.
Which debugging tests should I run? If I click on the ‘Test and Troubleshoot’ icon, I cannot find a test for BrickPi+.
Thanks for looking into it.
My desktop looks like this:
The test and troubleshoot screen looks like this:
Ok so you are using raspbian for robots then and a BrickPi3. The problem is you are trying to run BrickPi+ code on the new BrickPI3. It cannot work. So you need to run the code in the BrickPi3 folder. Also check out the BrickPi3 documentation, you can most likely find most of your answers there, of course you can always ask questions here! 
Your BrickPi3 probably looks different because the one in the video is most likely an old one.
Run the Test and Troubleshoot for BrickPi3. I got BrickPi3 not connected.
Try to run the software update for BrickPi3. The followings are the log:

Updating the BrickPi3 SAMD Firmware with ‘/home/pi/Dexter/BrickPi3/Firmware/brickpi3_firmware.bin’.
I tried to run BrickPi3 codes but got an error of 'BrickPi3 not connected
Could you run the Debugging tests? You just opened it up but didn’t run it. Just open it and click on Troubleshoot BrickPi3. Then could you print the output?
Also make sure the BrickPi3 is connected properly on the pins, that can cause an error.
I clicked the button ‘Troubleshoot BrickPi3’ and I was told all the tests are done very quickly.
The log simply stated ‘BrickPi3 not connected’
I ran the test with raspberry Pi powered by USB and BrickPi powered by battery ( I have switched on Brickpi )
Also tried to power using the battery from BrickPi. The same result.
Not sure there is any issue with the pin connection as (1) Raspberry Pi can be powered by BrickPi and (2) when I ran the LED test, by connecting LED directly to the corresponding pin on BrickPi, the LED flashes.
If I try to update the software of BrickPi3, I see several errors in the log. Does it imply hardware issue?

Updating the BrickPi3 SAMD Firmware with ‘/home/pi/Dexter/BrickPi3/Firmware/brickpi3_firmware.bin’.
Based on your pictures, you have a BrickPi3. Only BrickPi3 software will work with your BrickPi3.
What do you mean by “connecting LED directly to the corresponding pin on BrickPi, the LED flashes”? Do you mean you connected an LED to the RPi GPIO header, and it flashed when you ran the LED test? In that case, you were running the LED test for the older BrickPi.
Can you run this command in the terminal and show me the output?
sudo bash /home/pi/Dexter/BrickPi3/Firmware/brickpi3samd_flash_firmware.sh
The BrickPi3 has two LEDs. The green LED near the power switch indicates if the BrickPi3 is powered. The yellow LED near the power jack normally flashes to indicate battery voltage level, but can be controlled by user software. See here for expected LED behavior (again, user software can take control of the yellow LED).
You are right about what how I did the LED test.
The following is the output of your command ( I did it several times and seems to get different results )

Thanks Matt and graykevinb. It works now about running the script suggested by Matt. Thanks a lot!
