Matrix Portal M4 can't find MATRIXBOOT

Post by jsnebben »

I'm following the matrix portal M4 setup instructions and can't get the MATRIXBOOT drive to appear. I've tested my usb c cable with another device and that worked for data connection. When I try doubleclicking the reset button the neopixel doesn't turn on at all instead of turning red or green like the Install CircuitPython step mentions. Any idea what else I could be missing?

Do you see the CIRCUITPY drive?

Do you see any activity on the NeoPixel or LED at all?

Does a serial port show up for it?

Can you upload a sketch (e.g. blink) from Arduino?

I get no activity at all.

No serial port shows up.

I'm not able to upload a sketch from arduino.

Is this with the MatrixPortal on it's own with nothing connected to it?

I've tried it both connected to and disconnected from a 64x32 rgb led matrix and had the same result

OK. It sounds dead.

Please email [email protected] with a link to this thread, your order number, and request the replacement of one MatrixPortal M4.

I'm having the exact same problem as this post.

The product in question: the Matrix Portal M4 just like this post (Order #2664168-7223650718)

The problem: my computer isn't recognizing when the matrix portal is plugged in.

Steps followed: I followed the Further Information section from the MatrixPortal M4 Install CircuitPython page (https://learn.adafruit.com/adafruit-mat ... cuitpython). I get two solid green lights (v3 and v5) but the NeoPixel RGB LED never lights up. My computer also does not recognize that there is a new device plugged into one of the USB ports.

Troubleshooting:
1.) I've tried four different USB-C cables. One of which was new with this order (in the description it says that it transfers data as well as charges)
2.) I've tried this on multiple USB ports on my computer (Windows 10)
3.) I've tried on another computer as well (Ubuntu 18.04)
4.) I've tried various double-click intervals on the reset button while plugged into each computer
5.) I've tried with (and without) connecting it to the matrix display panel
6.) I've tried using UsbTreeView.exe to reset USB ports and reconnecting
7.) I've tried connecting the USB to a USB hub
8.) I've also tried rebooting my pc and attempting the above steps again as well as disconnecting all other USB connections

I'm not sure what else I can try to do.
