Hello Lars-Peter,
i followed the instructions on:
http://wiki.analog.com/resources/tools-software/linux-software/sigmadsp_genf...
and built the firmware from my xml-file. But when the driver loads, I always get:
adau1701 2-0034: Failed to load firmware: Invalid version 2. Supported firmware versions: 1 adau1701 2-0034: Failed to load firmware adau1701 2-0034: ASoC: can't set adau1701 hw params: -22
I have been using that .xml/.bin file in 3.14.13 for some time, but now in 3.18.3 I always get the version mismatch from above.
Hi,
Are you sure that the you were previously using a v2 firmware file? v2 was not supported until recently and loading it with the v1 loader would just result in garbage being written to the device.
The patch[1] that adds support for v2 is pretty standalone and you should be able to backport it to v3.18.
