CM3I with WiFi module AP6745

#1

Hello!

I have Radxa E25 and two different CM3I modules: the first one with SOC RK3568 and WiFi/BT module AP6256, and the second one with SOC RK3568J and AP6745. In the system i have installed firmware packages broadcom-wifibt-firmware_2.6_all.deb and brcm-patchram-plus1_0.2_arm64.deb. But module with AP6745 doen’t initialize correctly (wlan0 doesn’t appear):

Is this problem with firmware files or device-tree?

Hi,
You can refer to the configuration of this dts，https://github.com/radxa/kernel/blob/linux-5.10-gen-rkr4.1/arch/arm64/boot/dts/rockchip/rk3568-radxa-cm3i.dtsi#L545
or use the latest image https://github.com/radxa-build/radxa-e25/releases/download/b21/radxa-e25_debian_bullseye_cli_b21.img.xz

#3

My device tree node properties exact as reference from 5.10-gen-rkr4.1 kernel that you provided, except one property ‘supports-sdio’.
With this reference image, wireless interface doesn’t appear in system too. Log from image radxa-e25_debian_bullseye_cli_b21.img.xz:

I think firmware doesn’t loading to the module. On CM3I with AP6256 dmesg always have log message about firmware info: brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM4345/9 wl0: Feb 11 2020 11:54:51 version 7.45.96.61 (be7af2d@shgit) (r745790) FWID 01-a41d86bd es7.c5.n4.a3"

#4

Hi,
If AP6256 works normally but AP6745 does not, you need to check whether the hardware of AP6745 is normal. We tested AP6256 and AP6745 before the release of radxa-e25_debian_bullseye_cli_b21.img.xz and both of them can work normally.
AP6256 and AP6745 use the same driver and firmware

#5

Yea, thanks for your help. It was a hardware problem. On another module with AP6745, Wi-Fi works fine.
