@iamdrq i remove the patch and bt works, thanks! wzkiro@rockpi4bp:~$ uname -a Linux rockpi4bp 5.15.85-rockchip64 #trunk SMP PREEMPT Thu Dec 22 03:00:28 PST 2022 aarch64 GNU/Linux wzkiro@rockpi4bp:~$ sudo dmesg | grep -E "Blue|brcm" [ 8.468214] Bluetooth: Core ver 2.22 [ 8.469180] Bluetooth: HCI device and connection manager initialized [ 8.469193] Bluetooth: HCI socket layer initialized [ 8.469198] Bluetooth: L2CAP socket layer initialized [ 8.469221] Bluetooth: SCO socket layer initialized [ 8.732341] Bluetooth: HCI UART driver ver 2.3 [ 8.732356] Bluetooth: HCI UART protocol H4 registered [ 8.732359] Bluetooth: HCI UART protocol BCSP registered [ 8.732419] Bluetooth: HCI UART protocol LL registered [ 8.732423] Bluetooth: HCI UART protocol ATH3K registered [ 8.732448] Bluetooth: HCI UART protocol Three-wire (H5) registered [ 8.732700] Bluetooth: HCI UART protocol Intel registered [ 8.732820] Bluetooth: HCI UART protocol Broadcom registered [ 8.732863] Bluetooth: HCI UART protocol QCA registered [ 8.732866] Bluetooth: HCI UART protocol AG6XX registered [ 8.735141] Bluetooth: HCI UART protocol Marvell registered [ 8.819001] brcmfmac: F1 signature read @0x18000000=0x15294345 [ 8.822932] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43456-sdio for chip BCM4345/9 [ 8.828068] usbcore: registered new interface driver brcmfmac [ 8.991602] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43456-sdio for chip BCM4345/9 [ 9.000345] 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 [ 9.001146] systemd[1]: Reached target Bluetooth.

@iamdrq Oh! Thanks. How do you find that? Maybe i can update to 5.15.y, ahhh

Hi guys, I am building armbian image for rockpi4b+ and its kernel is 6.0.11(edge version) and the bluetooth failed start up. If anyone knows what kernel 6.0.11 did that cause the problem: wzkiro@rockpi-4bplus:~$ dmesg | grep brcm [ 7.069061] brcmfmac: F1 signature read @0x18000000=0x15294345 [ 7.108688] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43456-sdio for chip BCM4345/9 [ 7.109142] usbcore: registered new interface driver brcmfmac [ 7.236547] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43456-sdio for chip BCM4345/9 [ 7.245940] 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 wzkiro@rockpi-4bplus:~$ dmesg | grep Bluetooth [ 7.089775] Bluetooth: Core ver 2.22 [ 7.089894] Bluetooth: HCI device and connection manager initialized [ 7.089914] Bluetooth: HCI socket layer initialized [ 7.089922] Bluetooth: L2CAP socket layer initialized [ 7.089943] Bluetooth: SCO socket layer initialized [ 7.394043] Bluetooth: HCI UART driver ver 2.3 [ 7.394074] Bluetooth: HCI UART protocol H4 registered [ 7.394081] Bluetooth: HCI UART protocol BCSP registered [ 7.403820] Bluetooth: HCI UART protocol LL registered [ 7.403831] Bluetooth: HCI UART protocol ATH3K registered [ 7.405384] Bluetooth: HCI UART protocol Three-wire (H5) registered [ 7.416771] Bluetooth: HCI UART protocol Intel registered [ 7.440646] Bluetooth: HCI UART protocol Broadcom registered [ 7.453388] Bluetooth: HCI UART protocol QCA registered [ 7.453410] Bluetooth: HCI UART protocol AG6XX registered [ 7.459664] Bluetooth: HCI UART protocol Marvell registered [ 9.738700] Bluetooth: hci0: command 0xfc18 tx timeout [ 13.642153] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 13.642193] Bluetooth: BNEP filters: protocol multicast [ 13.642220] Bluetooth: BNEP socket layer initialized [ 17.894543] Bluetooth: hci0: BCM: failed to write update baudrate (-110) [ 17.894570] Bluetooth: hci0: Failed to set baudrate [ 19.910475] Bluetooth: hci0: command 0x0c03 tx timeout [ 28.484626] Bluetooth: hci0: BCM: Reset failed (-110)
