Can’t send SPI message - Resin.io

[pcg108]

I am using a Raspberry Pi 3 with a Matrix Creator board and resin.io. Resin uses dockerfiles to push deployments to multiple connected devices, and using the Matrix documentation in the matrix-creator-hal readme I installed the necessary dependencies for the board through the dockerfile and tried to run the “mic_energy_direct” demo.

However, I get the following output when running any of the matrix examples that involve the microphones:

“can’t send spi message”

This does not occur with any LED or sensor examples, just ones involving the microphone array. I have no problem running the examples in a regular (non-Resin) installation.

Resin enables spi by default, but I also used modprobe spi-bcm2835 in the RUN command to no avail.

Has anyone had success using Matrix+Resin.io? Any help would be greatly appreciated.

Here is my dockerfile, for reference:
