To add to this, I did a fresh install of the Ubuntu Desktop, no lubuntu. I got the same issues with Wifi working on and off, and bluetooth not working. $ sudo journalctl -k --grep=brcmfmac Feb 09 10:11:51 MacBookPro14-1 kernel: usbcore: registered new interface driver brcmfmac Feb 09 10:11:51 MacBookPro14-1 kernel: brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac4350c2-pcie for chip BCM4350/5 Feb 09 10:11:51 MacBookPro14-1 kernel: brcmfmac 0000:02:00.0: Direct firmware load for brcm/brcmfmac4350c2-pcie.Apple Inc.-MacBookPro14,1.bin failed with err> Feb 09 10:11:51 MacBookPro14-1 kernel: brcmfmac 0000:02:00.0: Direct firmware load for brcm/brcmfmac4350c2-pcie.txt failed with error -2 Feb 09 10:11:51 MacBookPro14-1 kernel: brcmfmac 0000:02:00.0: Direct firmware load for brcm/brcmfmac4350c2-pcie.clm_blob failed with error -2 Feb 09 10:11:51 MacBookPro14-1 kernel: brcmfmac 0000:02:00.0: Direct firmware load for brcm/brcmfmac4350c2-pcie.txcap_blob failed with error -2 Feb 09 10:11:51 MacBookPro14-1 kernel: brcmfmac: brcmf_c_process_clm_blob: no clm_blob available (err=-2), device may have limited channels available Feb 09 10:11:51 MacBookPro14-1 kernel: brcmfmac: brcmf_c_process_txcap_blob: no txcap_blob available (err=-2) Feb 09 10:11:51 MacBookPro14-1 kernel: brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM4350/5 wl0: Nov 26 2015 03:48:57 version 7.35.180.133 (r602372) FWID 01-> Feb 09 10:11:51 MacBookPro14-1 kernel: brcmfmac 0000:02:00.0 wlp2s0: renamed from wlan0 ~
also audio does not work but can get it working with: https://askubuntu.com/questions/1475091/sound-macbook-pro-ubuntu-22-04 apt install wget make gcc linux-headers-generic git clone https://github.com/davidjo/snd_hda_macbookpro.git cd snd_hda_macbookpro/ ./install.cirrus.driver.sh reboot -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/2097681 Title: Bluetooth not working, firmware issue Status in linux-firmware package in Ubuntu: New Bug description: $ lsb_release -rd No LSB modules are available. Description: Ubuntu 24.04.1 LTS Release: 24.04 Hello, Installed lubuntu with ubuntu desktop on macbook pro 14. Got the audio and wifi working, now it is the bluetooth that is not working (also camera does not work, but that is a seperate ticket). on boot up I gett a message: (might nott be exact spelling) Bluetooth: hc10: failed to set baudratoclm_blob available brcafaac: brcaf_c_process_txcap_blob: no txcap_blob available when looking at firmware I get these errors: $ dmesg | grep -i firmware [ 0.094904] ACPI: [Firmware Bug]: BIOS _OSI(Linux) query ignored [ 2.962727] brcmfmac 0000:02:00.0: Direct firmware load for brcm/brcmfmac4350c2-pcie.Apple Inc.-MacBookPro14,1.bin failed with error -2 [ 2.970379] brcmfmac 0000:02:00.0: Direct firmware load for brcm/brcmfmac4350c2-pcie.txt failed with error -2 [ 2.977520] brcmfmac 0000:02:00.0: Direct firmware load for brcm/brcmfmac4350c2-pcie.clm_blob failed with error -2 [ 2.977651] brcmfmac 0000:02:00.0: Direct firmware load for brcm/brcmfmac4350c2-pcie.txcap_blob failed with error -2 [ 3.460064] brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM4350/5 wl0: Nov 26 2015 03:48:57 version 7.35.180.133 (r602372) FWID 01-c45b39d6 [ 3.488798] i915 0000:00:02.0: [drm] Finished loading DMC firmware i915/kbl_dmc_ver1_04.bin (v1.4) I tried installing the firmware like this without any luck: $ sudo apt install firmware-brcm4350 Reading package lists... Done Building dependency tree... Done Reading state information... Done E: Unable to locate package firmware-brcm4350 The weird thing is, sometimes on bootup the bluetooth does work and am able to connect to my wireless mouse, it is just very sparingly and not dependable. It is understandable that there are so much issues with macbooks, I am just trying to give it a new life. here are some message outputs: $ dmesg | grep -i bluetooth # Shows all Bluetooth driver info dmesg | grep -i bluetooth | grep -i firmware # Shows Bluetooth firmware issues [ 2.747257] Bluetooth: Core ver 2.22 [ 2.747276] NET: Registered PF_BLUETOOTH protocol family [ 2.747278] Bluetooth: HCI device and connection manager initialized [ 2.747282] Bluetooth: HCI socket layer initialized [ 2.747285] Bluetooth: L2CAP socket layer initialized [ 2.747289] Bluetooth: SCO socket layer initialized [ 2.840975] Bluetooth: HCI UART driver ver 2.3 [ 2.840979] Bluetooth: HCI UART protocol H4 registered [ 2.840981] Bluetooth: HCI UART protocol BCSP registered [ 2.841006] Bluetooth: HCI UART protocol LL registered [ 2.841007] Bluetooth: HCI UART protocol ATH3K registered [ 2.841021] Bluetooth: HCI UART protocol Three-wire (H5) registered [ 2.841048] Bluetooth: HCI UART protocol Intel registered [ 2.845863] Bluetooth: HCI UART protocol Broadcom registered [ 2.845881] Bluetooth: HCI UART protocol QCA registered [ 2.845883] Bluetooth: HCI UART protocol AG6XX registered [ 2.845894] Bluetooth: HCI UART protocol Marvell registered [ 4.219738] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 4.219744] Bluetooth: BNEP filters: protocol multicast [ 4.219748] Bluetooth: BNEP socket layer initialized [ 5.157820] Bluetooth: hci0: command 0xfc18 tx timeout [ 5.157830] Bluetooth: hci0: BCM: failed to write update baudrate (-110) [ 5.157834] Bluetooth: hci0: Failed to set baudrate [ 7.206170] Bluetooth: hci0: command 0xfc18 tx timeout [ 7.206185] Bluetooth: hci0: BCM: Reset failed (-110) would I be able to get the firmware elsewhere? for example: https://repology.org/project/broadcom-bt-firmware/versions Would greatly appreciate the guidance.
