Hi all,
MATRIX Creator running on a RPi 3. I am seeing the following behavior:
I get the zero values both via MALOS and via the demo applications in matrix-creator-hal. The latter was built from the latest version on git.
Anyone have any idea about the cause and how to resolve?
Thanks!
Sorry for the self-reply: Let me document what worked for me, in case anyone else has the same issue.
Following the discussion at https://github.com/matrix-io/matrix-creator-malos/issues/8, I re-ran the script that programs the MCU:
sudo /usr/share/admobilize/matrix-creator/sam3-program.bash
That seems to have done the trick.
Hi,
I’m trying to do the same here but it didn’t worked for me 
. Anyone have any idea about the cause and how to resolve?
Thanks in advance!

Hi @Per,
Normally when something like this happen you just have to try again and it should work. Not just only reboot , power off everything and start again. It seems that you are doing everything right.
Please write us if you can’t make this work … and if it work too !!
Yoel
Thanks @ Yoel
Still no success.I did the following things:
completely removed the matrix creator from my RPi and again put it on my RPi (of course I shutted it down before).
I have tried to run the creator-init.bash too:
sudo /usr/share/admobilize/matrix-creator/creator-init.bash

I might have same problem as Per. I am currently using SSH to use the Rasbian command line from my computer, but I do not think that is causing this.
I read the log file it mentions:

Not sure if any of that helps. I will try resetting, updating, cut the power, and so on and get back when I got more information.
Rebooting did not change much, will try to update, then upgrade, reboot, try the bash again, then maybe full-upgrade, then reboot then try again.
But things that might be worth mentioning. First I tried the Alexa voice demo, then I tried a few other demos. Like a demo to try out IR, making it possible to see when it received an IR signal. I have also tried the arc_demo and everloop demo and they work fine. I did it because of the e-mail about how some power supplies might be faulty, but it seems my PSU is fine in this case. But the compass demo, sensors demo, servo demo all seem to get no values at all. They run fine, just seemingly no input.
When I try to update I usually get this error, which might not be a problem, but here it is
Err http://packages.matrix.one ./ Packages
404 Not Found [IP: 172.217.22.48 80]

E: Some index files failed to download. They have been ignored, or old ones used instead.
E: Couldn't rebuild package cache
So it seems to have a problem getting two packages, and it also does not seem to upgrade
I also tried with the sensors_demo, and it was the same. Since it stopped being all zeros after powering off, I figured it would be an idea to try power cycle it again then check the values, and they do change after a power cycle. So I tried rebooting, and the values also change after rebooting. Breaking the demo and then running the sensor demo again does not change the values.
I have been reading different topics in this troubleshooting topic, and one suggestion that was made was to power off the Pi completely and take apart the Pi and the Matrix. So I tried that, and now the sensors are not showing zeroes all over, but they still seem fixed.
The compass example, I suspect the LED lights should be moving when you move the Matrix around, but they are static, and keep blinking in the same LEDs, with the same colors, or just the same blue or red light.
Okay, now I finally got it working. I had forgotten about the command:
sudo /usr/share/admobilize/matrix-creator/sam3-program.bash
After having gotten it to do readings, this command worked. So after it had programming the FPGA I rebooted just to be safe, then ran the sensors demo. It now showed zeros again. I tried rebooting again, still zeros. I tried the bash command again, but it just said it was already programmed. So I took the power from the Pi, took off the Matrix again, reconnected it again and connected the power again.
Now the readings are finally updating 
So, to try and sum up the other stuff I did, I ran a git pull in every folder. I guess the most important ones would be matrix-os and matrix-creator- hal. Then I ran:
sudo apt-get update
and
sudo apt-get upgrade
Then did a cmake and make in the matrix-creator-hal/build folder. Then bash again:
sudo /usr/share/admobilize/matrix-creator/sam3-program.bash
Then pulled power from the Pi, took off the Matrix. Waited 5-10 seconds as is usually a good idea when making sure a device has lost all power, put the Matrix back in the Pi, powered on and ran
./matrix-creator-hal/build/demos/sensors_demo
and the readings are updating. Hope this will help others save some time.
I have tried every remedy in this thread multiple times, and sam3-program.bash still fails:

Actually, looking closer at those errors, they look like RAM errors I think?
I see similar errors in the log file when I run:
sudo /usr/share/admobilize/matrix-creator/sam3-program.bash
unexpected device ID codes coming back on JTAG?

Are you having troubles getting data from the sensors? Can you show what tests have you donde so far?

Hi @yoelrc88
I just run the sensors demo program I got from here:
LED demos work (once I switch to a better supply for the rpi) but sensor demos only returning “0”. My MCU will not reflash same issues discussed here.
SOLVED?
At least two people still have this problem!
@analog71 I got tired of messing with it. For now, I’m assuming it’s an unrecoverable hardware failure. I had hoped for better…
Hi @BobC an others ,
Please check this announce Debian packages have been updated - MCU troubles.
Try this and let us know the results.
