Bug #1137

No wifi interface found
20%
Description
Pinet doesn't work because there is no wifi interface.
Notes:- PPP Schematic
- According to the schematic, the chip is AW-CM256SM which is both BT and WiFi.
- The DTS shows Bluetooth is brcm4345c5, but that appears to just be a BT driver, not WiFi.
bluetooth { compatible = "brcm,bcm4345c5"; .... }; - See also
- RockPro64 Hardware Tweaks for same Wifi chip
- Armbian Firmware supposedly supports the RockPro64 wifi.
- Cypress Linux Driver
See this discussion on the pine64.org forum. Apparently it uses similar firmware to the RPi, which is available from the Debian firmware-brcm80211 package.
On a Debian (based) system, install firmware-brcm80211 package and then do this: Code: cd /lib/firmware/brcm/ ln -s brcmfmac43455-sdio.AW-CM256SM.txt brcmfmac43455-sdio.pine64,rockpro64-v2.0.txt ln -s brcmfmac43455-sdio.AW-CM256SM.txt brcmfmac43455-sdio.pine64,rockpro64-v2.1.txt That should be all you need.

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.

It's possible I just didn't have the megi fw installed. I've fixed that in the xeon2 sandbox. I need to just copy the fw to the phone and reboot to see if that's sufficient to get the wifi interface to show up. I don't see the driver I expected to be enable in the kernel config, but maybe I'm looking at the wrong one.

That's not it - there were firmware blobs already there from megious, but they were a bit out of date.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 Bluetooth: hci0: BCM: 'brcm/BCM4345C0.pine64,pinephone-pro.hcd' Bluetooth: hci0: BCM: 'brcm/BCM4345C0.hcd' Bluetooth: hci0: BCM: 'brcm/BCM.pine64,pinephone-pro.hcd' Bluetooth: hci0: BCM: 'brcm/BCM.hcd' brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43455-sdio for chip BCM4345/6 brcmfmac mmc0:0001:1: Direct firmware load for brcm/brcmfmac43455-sdio.pine64,pinephone-pro.bin failed with error -2 brcmfmac mmc0:0001:1: Direct firmware load for brcm/brcmfmac43455-sdio.bin failed with error -2 brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50
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 psci: PSCIv1.1 detected in firmware. panel-himax-hx8394 ff960000.mipi.0: Direct firmware load for hx8394-mode.bin failed with error -2 Bluetooth: hci0: BCM: firmware Patch file not found, tried: Goodix-TS 3-0014: Direct firmware load for goodix_1158_cfg.bin failed with error -2 brcmfmac mmc0:0001:1: Direct firmware load for brcm/brcmfmac43455-sdio.pine64,pinephone-pro.bin failed with error -2 brcmfmac mmc0:0001:1: Direct firmware load for brcm/brcmfmac43455-sdio.bin failed with error -2 cdn-dp fec00000.dp: Direct firmware load for rockchip/dptx.bin failed with error -2 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.

Made a symlink from /lib/firmware (Megi's fw) to /usr/lib/firmware, but this didn't help.
$ dmesg | grep firmware psci: PSCIv1.1 detected in firmware. panel-himax-hx8394 ff960000.mipi.0: Direct firmware load for hx8394-mode.bin failed with error -2 Bluetooth: hci0: BCM: firmware Patch file not found, tried: Goodix-TS 3-0014: Direct firmware load for goodix_1158_cfg.bin failed with error -2 cdn-dp fec00000.dp: Direct firmware load for rockchip/dptx.bin failed with error -2 brcmfmac mmc0:0001:1: Direct firmware load for brcm/brcmfmac43455-sdio.pine64,pinephone-pro.bin failed with error -2 brcmfmac mmc0:0001:1: Direct firmware load for brcm/brcmfmac43455-sdio.bin failed with error -2 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
Of these, I found the following:
$ find linux-firmware/ -name dptx.bin linux-firmware/rockchip/dptx.bin $ find megi-firmware/ -name brcmfmac43455-sdio.bin megi-firmware/brcm/brcmfmac43455-sdio.bin
I don't know where the rest would come from, or why brcmfmac43455-sdio.bin was not found.
Update:- The Goodix firmware is not required - the touchscreen is working without it.
