Just got myself a Toneboard.
I’m running the TB attached to an RPi4 (Raspbian)
If I connect the TB straight to RPi-USB all is fine.
Now the issue starts when running dual-power-rails
I have an Allo Shanti PS, which comes with two 5V rails.
One rail powers the PI and the other one the Toneboard.
I accomplish this by feeding the TB using an iFi iDefender3.0
The TB simply doesn’t get recognized all the time this way.
I already changed the “rootdelay” param to avoid that the RPi boots up before
the TB is up’n running.
lsusb doesn’t show the XMOS device in this case.
reboot doesn’t change the situation.
Any idea what else I could try?
