execute all as root

sudo su

(first time only) install required packages

apt-get install raspberrypi-kernel-headers gcc make device-tree-compiler git

(first time only) download Hermes-RPi driver sources

git clone https://github.com/miero/tpa-hermes-rpi-dev.git

enter driver directory

cd tpa-hermes-rpi-dev

(upgrade only) download current Hermes-RPi driver sources

git pull

build and install modules and overlay file from the tpa-hermes-rpi-dev directory

make clean
make install
depmod -A

(first time only on most RPi distros) append loading tpa-hermes-rpi overlay into config.txt

echo "dtoverlay=tpa-hermes-rpi" >> /boot/config.txt

(first time only on DietPi) append loading tpa-hermes-rpi overlay into config.txt

reboot

reboot

verify that the driver is loaded

aplay -l

tpa-hermes-rpi-dev's Issues

Error writing from AlsaSink buffer to PCM

Hi Miero

Been testing with raspotify and librespot that uses alsa backend but i think there is a driver issue.
DietPi version: ARMv7 32-bit Bullseye

Error:

Nov 26 22:03:39 DietPi librespot[1197]: [2021-11-26T21:03:39Z WARN  librespot_playback::audio_backend::alsa] Error writing from AlsaSink buffer to PCM, trying to recover, ALSA function 'snd_pcm_writei' failed with error 'EIO: I/O error'
Nov 26 22:03:39 DietPi librespot[1197]: [2021-11-26T21:03:39Z ERROR librespot_playback::player] Audio Sink Error On Write: <AlsaSink> ALSA function 'snd_pcm_recover' failed with error 'EIO: I/O error'

Output of aplay -L:
