Tone Board not detected on reboot (Armbian)


#1

I have strange problem. Any advice?
OS - balbes150’s Armbian (debian, server, kernel 3.14.29)
VIM Pro

When Tone Board is connected to the VIM trough USB cable, everything works normal. But when trough GPIO, it is not detected after reboot (shutdown -r now) or even after power on if was executed shutdown command first. If i remove power cable and put it again - the Tone Board appears again.

Hi, Stefan:
Here we will confirm first then update you.

@Ben007 Maybe it’s power on/off logic cause this?

on my home built (using fenix scripts) ubuntu xenial w/ kernel 4.9.40 :
I plug the toneboard (generic model) on the gpio 40 pins socket,
then I connect the usb-c cable from the VIM1 pro to my laptops’ usb-A port,
I use minicom and a console serial USB cable to see the boot message,
I log in , then…

aplay -D plughw:CARD=x20,DEV=0 police_s.wav
Playing WAVE 'police_s.wav' : Unsigned 8 bit, Rate 22000 Hz, Mono

and music gets out of the RCA socket of the toneboard
then, I do
sync; sudo reboot

and again, the toneboard just works once ubuntu is rebooted

If this can help balbes150 to diagnose what happens with his Armbian+kernel 3.14

When you connect Tone Board with 40 PIN GPIO,it didnot need connect USB-C power cable.
Actually,if you plug USB-C with PC and the same time connect tone Board with VIMs,and tone board will swtich to PC sound card.
