device /sys/devices/platform/bb800000.pci/pci0000:00/0000:00:00.0/ppp is not ready.

in fact ,dectect node via "echo -n "PUT pipeline1/volume.elt/volume0/gain=0.6" > /sys/devices/platform/bb800000.pci/pci0000:00/0000:00:00.0/ppp" , but response always is ERROR.

how does l fix it ? thanks

Hello Zhao,

Do you have connected the Audio board to the MX8MMini? this kinds of issues give you when you have not connected.

Regards

Hi，Bio

l have confirmed that connect ribbon cable from J1001 of i.MX8MMini EVK board to J2500 of Audio board.

but audio board have not inserted DC powerd , not connect HDMI output of DVD/Blu-Ray player to HDMI RXC input port of Audio board.

Is it necessary to supply power to audio board separately?

thanks

Yes, you need power the Audio board

HDMI OUT to TV
