AC’97 Audio on i.MX6 Qseven Development Platform

Nov'12

iWave is the first in the world to design and successfully test the AC’97 Audio functionality in Freescale's i.MX6 CPU. iWave's core Linux BSP team has broken the boundaries & implemented the AC’97 Audio interface on Linux BSP and successfully tested AC’97 Audio In/Out on iWave’s i.MX6 Qseven Development platform called RainboW-G15-Q7D. Since Qseven specification 1.2 strictly requires AC’97 interface for audio interface, AC’97 Audio availability for i.MX6 CPU is the new milestone achieved by iWave in ARM Q7 arena. Though the newly published Qseven R2.0 specification included the I2S interface for audio, most of the existing Qseven carriers support the AC97 codec. This imposes the bottlenecks on using the Qseven SOMs with audio interface requirement. By testing AC’97 Audio on i.MX6 CPU, iWave has broken this bottleneck of using ARM core CPUs with audio in Qseven form factor.
