Hi, i am trying to load the everloop demo to my matrix voice but I always get an error.

esptool write_flash: error: argument <address> <filename>: Address "/tmp/build/everloop_demo.bin" must be a number

I have done all the steps from: https://github.com/matrix-io/matrixio_hal_esp32
Everything worked fine expect the last step where I should flash the Matrix Voice.

Can someone please help me with that.
I am really frustrated about that and I slowly start disliking this product because I can’t even get a basic example running.

Thanks in advance for your help.

Matrix Voice ESP32: problem with Build and Make
#2

Are you using a Windows or a Linux PC for the esp-idf installation?

#3

I am using Mac OS.
I already tried Windows which failed totally.
I can try in a virtual machine with linux, but I would prefer Mac OS

#4

Is the first time I see this error. I found this issue in the esptool tool. Unfortunately, the answer doesn’t seem to help here in your case. I normally using a Linux PC, but will try to replicate with Mac OS.

#5

OK so i am going to try it with Linux also.

I installed Matrix OS in the mean time.
Is it also possible to install the Matrix OS directly on the ESP32 or do I need a raspberry pi for it?

#6

OK let me know.

For the MATRIX OS you need the Raspberry Pi.

#7

Alright.
Thank you :slight_smile:

#8

One more question…

What can I do when I start the HelloWorld Example on Matrix OS.
But no LED flashes?

#9

The Matrix has a Blue LED at the bottom on!

#10

Could be multiple things :slight_smile: . My suggestion is to open a new post so we can follow up on that on a defferent conversation.
