[Sound-open-firmware] .m4 File Request Help Needed
by Nahulanthran, Sanjeev 30 Jun '18

30 Jun '18

Hi there, Writing this e-mail to request for SOF support in providing a .m4 file with 48kHz, TDM8, and MCLK enabled - used for Cirrus Logic CS42435. This is required as we need it as a reference to make our own modifications to enable the same configuration for another device (amplifier) that we have. Thanks and Regards, Sanjeev Software Engineer

Hi Liam, Here I worked out a spec file to fit thesof/crosstool-NG in Clear Linux building environment. It worked by adding below tar-balls and some changes. But except for the crosstool-ng and xtensa-overlay, the others are common tool not real source. Could you change the make file to regard those common tool as dependencies?
