Testing ad9833 with Diolan DLN2 adapter

[Gaston Gonzalez <gascoar@xxxxxxxxx>]

Hi,

I am trying to test an ad9833 module like the one in [1] using Diolan DLN2
adapter and the driver ad9834.c

So far I get the DLN2 adapter correctly registered as master device
(below the spi debug output) but the ad9833 driver doesn't even probe.

Below the spi log output and pin connections. I'm using the testing
branch of the iio repo. The ad9834 and dln2 drivers were compiled as
modules.

The question is: should this setup probe or extra steps are needed?

Any help appreciated.

Thanks,

Gaston
