Hi
seems similar configuration "mem->dma-> asrc->dma->ssi" is used
on ESAI codec CS42888 SCH-26662 p.5 on Sabre AI board
Schematics (5)
Design files for i.MX 6Quad and i.MX 6DualLite CPU1 Cards
Design files for Base Board (REV E)
and one can look at its implementation in attached Linux Manual sect.
29.2.2 Sequence for Memory to ASRC to Peripheral.
Best regards
igor
