HiFiberry support in aarch64

Postby kernelpanic » Tue Oct 20, 2020 10:51 am

I'm unable to get my HiFiBerry DAC+ to work under aarch64.
I have followed the guidance at https://www.hifiberry.com/docs/software/configuring-linux-3-18-x/ and I have been able to get the card recognized under arch arm7

If I try:
$this->bbcode_second_pass_code('', '
[root@mail2 kernel]# modprobe snd_soc_hifiberry_dacplus
modprobe: FATAL: Module snd_soc_hifiberry_dacplus not found in directory /lib/modules/5.8.9-2-ARCH
[root@mail2 kernel]#
')
does It suggests that the required module isn't included in the arrch64 kernel?

Regards

Unfortunately, yes. The vendor never mainlined its driver(s), so the driver is only available in the Raspberry Pi kernel tree.

Support is available in the newly available linux-raspberrypi4 kernel for aarch64.
you loose uboot and the kernel reverts to 5.4.83 (as of today), but you do get hifiberry and other HAT capability.

Right, RPi4 + aarch64 for ArmARM now uses the rpi foundation kernel with libs/firmware for all the goodies. Currently rpi-5.4.y branch but we will switch over to rpi-5.10.y kernels sooner or later.

If you want, you can either:

1. Hit my unofficial repo and get the 5.10.y kernels now, instructions: http://repo-ck.com/aarch64-test/
2. Build your own from my 5.10.y branch of PKGBUILDs: https://github.com/graysky2/PKGBUILDs/commits/5.10.y
