I would like to add driver to TAS2557 to my system, which is in source kernel for Jetpack 4.6.1. Finally I will use TAS2563 which is compatible with TAS2557 (information is based on TI webside).
Can you tell me what I should do to use this driver with I2S3 (pins 220, 222, 224,226) and I2C3 (232, 234)
Selected SND_SOC_TAS2505 in kernel/nvidia/sound/soc/tegra_alt/Kconfig
Added “CONFIG_SND_SOC_TAS2505=y” in file kernel/kernel-4.9/arch/arm64/configs/tegra_defconfig
Main problem is with load driver in system (sound card doesn’t display in system). I get error:
[ 1.832278] tegra-asoc: sound: ASoC: CPU DAI DAP not registered
[ 1.838808] tegra-asoc: sound: snd_soc_register_card failed (-517)
I read about this error but solutions on forum didn’t help me to resolve this problem.
Below is dmesg log with enable debug for soc-core.c and tegra210_i2s_alt.c:: dmesg_log_all.txt (77.3 KB)
Since you replaced the kernel, what do you see for: uname -r
Also, are there modules or files at: /lib/modules/$(uname -r)/kernel/
(it doesn’t matter what files are there, I just want to know they are present for the kernel to find)
