- Supported kernel: 4.9.x, 4.14.x
The TFA9892 is a high efficiency class-D audio amplifier with a sophisticated speaker boost and protection algorithm
This codec driver requires firmware. Please download it from NXP codeaurora:
Place the firmware file in the following path on the target board:
/lib/firmware/tfa98/9912/TFA9892N1A_stereo_32FS.cnt
ln -sf /lib/firmware/tfa98/9912/TFA9892N1A_stereo_32FS.cnt /lib/firmware/tfa98xx.cnt
Codec driver will look for firmware under /lib/firmware/tfa98xx.cnt
To make and make install module for TFA98xx driver:
KDIR=<your kernel source path> make
KDIR=<your kernel source path> INSTALL_MOD_PATH=<absolute path of kernel module> make modules_install
(NOTE: The "modules" directory should be already installed kernel module inside)
Load the module driver on the board:
modprobe snd-soc-tfa98xx
