CM3I with WiFi module AP6745

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

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"

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

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