August 10, 20242 yr I am learning kernel dtb stuff & I have made a custom image which performs good as far as NPU VPU are concerned. However, I am missing something because WIFI is not detected. Following are some required outputs. My Pi is v2.1 & its WIFI/BT is broadcom chipset Additionally, i tried install armbian-full-firmware as well OS: Armbian (24.8.0-trunk) aarch64 Host: Rockchip RK3566 OPi 3B Kernel: 5.10.160-rockchip-rk356x Uptime: 13 mins Packages: 1327 (dpkg) Shell: bash 5.1.16 Terminal: /dev/pts/0 CPU: (4) @ 1.800GHz Memory: 493MiB / 3922MiB $ sudo lshw -C network *-network description: Ethernet interface physical id: f logical name: eth0 serial: 00:00:a4:82:ff:d7 size: 100Mbit/s capacity: 1Gbit/s capabilities: ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=st_gmac driverversion=Jan_2016 duplex=full ip=192.168.1.8 link=yes multicast=yes port=twisted pair speed=100Mbit/s $ sudo lsmod Module Size Used by sch_fq_codel 20480 2 zstd 16384 4 binfmt_misc 20480 1 sprdwl_ng 311296 0 sprdbt_tty 28672 0 fuse 110592 1 ip_tables 28672 0 ipv6 434176 44 panfrost 57344 5 gpu_sched 28672 1 panfrost rtc_rk808 16384 1 $ dmesg | grep -i wifi [ 16.715482] WCN: start_marlin [MARLIN_WIFI] [ 16.715496] WCN: marlin power state:0, subsys: [MARLIN_WIFI] power 1 [ 25.750599] sprdwl:[WIFI_CMD_SYNC_VERSION]timeout [ 25.750634] sprdwl:ctx_id:0 cmd: WIFI_CMD_SYNC_VERSION[9] rsp timeout (mstime = 15648), num=1 [ 38.650942] unisoc_wifi: probe of unisoc_wifi failed with error -1 armbianmonitor -u https://paste.armbian.com/owokujocuj Edited August 10, 20242 yr by ioncube update
August 11, 20242 yr Author OK I have some progress in debugging. Firmware files are present in right location `https://github.com/armbian/firmware/tree/master/brcm` However I have no loadable module like `brcmfmac` ... Now I want to get github link to make this module
