You will need to ensure that the pins that you're using are only declared
once in the fex on a enabled driver).
The muxing required for the spdif is as described in the fex file, the
driver should do the rest.
How do I set up the gpio correctly?

I've also noticed that i2s is declared twice in the fex.

Hi Dennis,
well for starters all the examples of A20 fexs in sunxi-boards only have
the spdif_dout gpio selected.
Do you need all three connections?, what external device are you connecting
to. The code as is doesn't

Here is my .fex file.

If you could also put your fex somewhere then I can compare the settings to
the code. There are two I
Yes I have modified my .fex file. I will look into the gpio.
The I2s works on my A10 board but not my A20 board, so I am tracking down
why.

If it's an optical connection you have then you should see the RED light if
What do you mean see the spdif illuminate?, I am currently just checking
the pins with a scope. I see no activity on the pins, so I probably need to
set up the gpio.
Yes, I can try out your patches. I am also still working on getting the I2s
to work correctly on the A20.

Hi Dennis,
I guess if aplay sees it then you've also added the change to the fex file
for your board(I see that the all the olimex boards have spdif disabled in
sunxi-boards). Do you see the spdif illuminate?, if not then the gpio needs
setting up correctly.
I've got some patches for the tidy up of
I have an Olimex A20 board. My kernel has SPDIF compiled in. aplay sees the
SPDIF and plays to it. But there is no data on the pins I have defined for
it.
What am I missing? What else do I need to setup to make this work?
