Dear erikly01:
Thanks for your feedback.
From the log you provide:
Module Size Used by
snd_soc_imx_tfa98xx 16384 0
It looks TFA9892 is not initialized properly.
I think it is caused by lack of firmware.
TFA9892 driver would look for a firmware.
It should be put under:
/lib/firmware/tfa98/9912/TFA9892N1A_stereo_32FS.cnt
We create a Yocto recipe to put firmware.
TechNexion/meta-edm-bsp-release@c5108e4
But it seems the Yocto image (pico-imx8m_pico-pi-imx8m_yocto-2.5-qt5_QCA9377_hdmi_20190430.zip) you use is outdated and without the TFA9892 firmware.
U-Boot 2018.03-tn-imx_v2018.03_4.14.98_2.0.0_ga-wip+g6dd7261 (Apr 25 2019 - 10:59:23 +0000)
Could you try the latest release for PICO-IMX8M?
ftp://ftp.technexion.net/demo_software/pico-imx8mq/pico-imx8m_pico-pi-imx8m_yocto-2.5-qt5_QCA9377_hdmi_20190821.zip
Itβs the first release image that starts to support Voicehat officially.
We enhance the WIKI to add the explanation about TFA98xx firmware after getting your feedback.
https://github.com/TechNexion/tfa98xx/wiki
BTW, share a tip with you.
Itβs convenient to specify Yocto kernel to use your local kernel repository.
Add the following lines in you conf/local.conf
KERNEL_SRC_pn-linux-tn-imx = "git:///home/xxx/workspace/linux_kernel_4.14.98_2.0.0_ga/tn-kernel "
SRCBRANCH_pn-linux-tn-imx = "tn-imx_4.14.98_2.0.0_ga-wip "
SRCREV_pn-linux-tn-imx = "${AUTOREV}"
Thank you ~!!!

Hi Henriparm & Richard, thanks for your quick response!!
I followed your instructions and now the Voicehat is working :)
My company is developing a HiFi device that uses the i.MX8 Mini for the SOM. Everything is working, but I have a question about I2S.
Is it okay if I email you directly?
