OK starting properly now.

The CS4385 has to get going within 10ms so I start this 1st after reset high , rather than having it wait around for the ADC

to initialize. I'd set rest high on ADC DAC then DSP and left the DAC waiting or the ADC to startup.

THINGS TO DO LIST...

check over SAI configs and DMA for playback / record slots and make sure recording / playback works on both hardware slots

dual recording to cards , have set up DMA but how to write to both card at same time.

recording armed tracks from TDM8 from BT app  ( not changing TDM mode , just recording slots from it ! ? )

recording both ADC DAC cards at the same time ? up to 16 channels wav poly or separate mono !!

playback of different track count from wav poly? just assign to playback slots in order recorder ? 

LTC timecode intergration into file recording. LTC timecode at start into wav header ?

NEW analouge board with OVR lines for analogue limiter on front end needed. ( old 4 channel analouge board needs updating ) 

power cards , dual +-5v , dual +-12v, phantom pwr to slot into new analouge board.

some kind of master 12v reg isolation eventually.
