MATRIX device has not been detected Again

Im having the same issue others are finding when setting up the Matrix.

Raspberry Pi 4 - 4GB
Latest Rasbian OS
Matrix Creator

I looked through all the threads, tried all the tips:

flashed with Kit
tried RPi 3B

Still nothing. Please help!

@Samreen has anyone found a solution yet? I love the potential of the board!


Could you try the following and let me know the output?

sudo xc3sprog -j -c sysfsgpio_creator

Since you have a MATRIX Creator, the command to check your FPGA connection is a bit different than the one you tried above. If your FPGA can be detected, we can go from there into diagnosing why it’s not working when running example code.


@Samreen here is the output. Thanks for helping out.

Hello ,

i have some problems !


Welcome to the community! Can you expand on what is happening?


Maybe this needs a new thread so I dont get emails.

By the way… this was never resolved for me… i returned the device in June… and STILL havent received a refund. Newark is horrible to deal with, and Matrix did not return my emails. Caution.

Hello Samreen,

I installed a new image Raspberry (Debian Buster) since I can’t connect my matrix creator .

here are the error messages
Please help!

To confirm, do you have a MATRIX Creator or MATRIX Voice?

Can you send me the output of

sudo xc3sprog -j -c sysfsgpio_creator

Additionally, since it seems you have the MATRIX kernel modules installed, can you send me the output of arecord -l and let me know if recording audio with the following command works?

arecord recording.wav -D hw:MATRIXIOSOUND -f S16_LE -r 16000 -d 5
aplay recording.wav

Please also create a new thread with your outputs so as not to bother the community member above. Thanks!
