Hi Curtis,
I am just curious what the status of Braswell devices are right now. If the status is unknown that is fine. I may be doing some experimenting with them in the near future. Any known issues or caveats would be appreciated. :)
braswell is essentially cherrytrail which is very nearly identical to baytrail except for an oscillator frequency. I tested SOF on Cyan a number of times in the past, so all the plumbing should already be there. The only caveat is that there is quite a bit of DMA rework at the moment so there might be some re-testing required if you take the latest development branch. Also our module load/reload tests failed, but it's more of a dependency with the max98080/TI aux chip that's not well handled than SOF proper.
well, it's really bad with the latest firmware and kernel:

I don't know when things went south so spectacularly but clearly the Intel validation isn't up to snuff. Gah.
