Hello Baozhu,
I am trying to configure Jetson nano with respeaker 4 mic array V1.0(AC108).
I have connected repeaker board on jetson nano’s 40-pin Expansion Header.
I have created DTS file for 4-mic array V1.0 with reference of 2-mic array which is successfully running on nano[0].
I have attached(later in this post) 2 dts [File_1 and File_2] files for 4mic.
Could not attach dmesg log so 2 log-prints mention below.
Prints from dmesg:
tegra-i2c 7000c400.i2c: no acknowledge from address 0x3b
