We are developing an IoT based product using NXP imx6ul processor. We have used the SPH0645LM4H microphone. The microphone is connected to the processor on the I2S bus. The processor runs on Linux 3.14.52. As of now we are working on board bring up of the processor but we are not able to find any Linux driver for the mic in the kernel source code (3.14.52). We are trying to capture raw audio from the mic in Linux user-space. All of the peripherals are up and running and we are kind of stuck with the mic. We need to get this phase of the project done Monday, 19th September at all costs. Hence we really need someone to provide us guidance. Can someone from your team help us out here?
Thanks in advance for any help that you can provide!
