Thanks for comment. I see you have support for audio i2s over hdmi (hdmi audio), but in openwrt there isn't hdmi support :)
Anyway i hope the dmaengine is not the problem, it 's look like the dma desc is made from alsa struct snd_pcm_substream *substream. I think this is my source of kernel crash because i haven't a good definition of control of my sound card, mixer, lineout, internal dac ... so i hope this is my source of Null Pointer, in fact not a dmaengine related issue. I try to have a bus based regmap to read/write the special little memory that store analog setup and update with better and non NULL function for alsa control. my first step is debug this memory PCMR or PMCR anyway i don't understand what this name mean :) -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
