I2S audio chip on ultimate dock

Tue Dec 13, 2016 11:30 am

In http://vonger.cn/misc/vocore2/source.zip, ES8388 manual is included.
On other hand, in schematics of Ultimate Dock, we see wm89xx.
Which is correct ?

ES8388 is used.
WM8988 and ES8388 are compatible.

I got OpenWrt/CC source tree with command guided in Wiki page.
> git clone -b VoCore2 https://github.com/Vonger/openwrt-chaoscalmer.git

For ultimate dock, I changed config to add MT7628 sound with OpenWrt's menuconfig and tried building.
But, the building failed because non-existence of es8388 driver.

In "VoCore2" branch, es8388 is described on Vocore2.dts, but no sourcecode files or patches for driver.

Please put the recent source outputs into git repository.

You may want to check out my github repo. Vonger hasn't updated his since he forked at the first of September. I have updated mine with Vonger's audio patches.

If you want to roll your own you can find the patches in my commit history.

Note: Chaos Calmer had a alsa driver (500-alsa.patch) but it has been removed from OpenWrt trunk and Lede because it was deemed broken.

Return to VoCore2/Lite/Ultimate
