PiBox » Xeon

According to Pine64 documentation the wifi component is the AzureWave AW-CM256SM which is the same as other devices in the Pine64 family. So the information in the Description would appear accurate.

The .txt files are in the upstream kernel.org firmware repo. The dev system build uses "master" for the primary branch but this has changed to "main", so this needs to be changed before pulling an update to get those files. Also, the Xeon build is pulling from Megous' firmware tree, which is not updated (and is still using "master"). So I'll need to pull the wifi firmware from upstream instead of from Megous.

That's not it - there were firmware blobs already there from megious, but they were a bit out of date. Updating them did nothing.

The kernel config has no loadable modules - everything is builtin. So this isn't a module loading issue.

Next step is to try enabling the modules I suspect are the appropriate ones and making sure the original hacks (in the issue description) are in place.

This is manjaro's loaded modules list.

I brcmfmac and brcmutil, not to mention the v4l2_h264, hantro_vpu and related video drivers. I'll start first with the brcmfmac and brcmutil drivers, along with the above mentioned files pulled from upstream kernel.org firmware.

The following are already configured in the defconfig.

CONFIG_BRCMFMAC=y
CONFIG_BRCMFMAC_PROTO_BCDC=y
CONFIG_BRCMFMAC_SDIO=y

Added the firmware files from upstream, made the symlinks, but no wifi. dmesg reports the following.

$ dmesg | grep brcm

I think the dts tries to load something different. I need to look at the DTS: arch/arm64/boot/dts/rockchip/rk3399-pinephone-pro.dts A quick gander shows that it is the cypress chip.

I need to check with Megi about this on IRC.

Built with just Megi's firmware tree and got this.

$ dmesg | grep firmware

platform regulatory.0: Direct firmware load for regulatory.db failed with error -2
cdn-dp fec00000.dp: Direct firmware load for rockchip/dptx.bin failed with error -2

The files that are failing are not in either megi's firmware tree or in upstream kernel.org firmware. Not sure where they come from yet.

So based on the ArchLinux build for PPP the firmware directory should be /usr/lib/firmware instead of /lib/firmware.
