Hi,
I usually have no problem compiling vanilla or Letux kernel, but Letux 4.9-rc4 produces a lot of this at boot on the EVM :
I've tried it here, and don't see those problems. I'm also using gcc 4.9, so i guess the compiler is the problem.
What i have been getting however is that it throws out
ts3a227e_interrupt ts3a227e_new_jack_state: plugged 0 mic_pres 0
about 100 times/second, making everything incredibly slow (with it going over the serial port). It only does it on the prototype, it works fine on the evm.
Ah, I see.
Hm. That is really interesting since the ts3a227e_interrupt is not triggered on my ts3a227 prototype for the new hardware release.
The pyra prototypes have a ts3a225 (like the EVM).
Maybe the ts3a227e driver is not checking that the chip is really installed and responding on i2c! Or maybe it is talking to the ts3a225 chip which is there and installs some interrupt handler.
So for the moment it could be sufficient to remove the snd-soc-ts3a227e.ko
Something else makes me wonder. The standard device tree file has no entry to load the ts3a227 at all.
Did you use the V5.1 device tree? That one is only for the new hardware.
BR and thanks, Nikolaus
