Are you sure you have that right? The correct setting is "options=broadcom_wl". Not what you typed.

Yes I used the correct option

Hi,

Could you install the latest r83 release if you are not using it, run brunch without "options=broadcom_wl" and attach a dmesg to this issue (run "dmesg > ~/Downloads/dmesg.txt" and post dmesg.txt from your Downloads folder) ?

Thanks for your help.

Download the below file:
brcmfmac43241b5-sdio.txt

Run sudo cp ~/Downloads/brcmfmac43241b5-sdio.txt /lib/firmware/brcm/ in crosh shell.

Then reboot and check if wifi is working.

Worked Instantly, i cant say how amazing skills you have, an wizard genius!!!

Maybe i need a firmware to Bluetooth too?
It appears to turn on as option but don't find anything.

My cameras and sensors are from Intel i think, compatible with Linux, do i need some drivers ?
the cameras are
Camera Sensor IMX175 and Sensor OV2722
Sensors didn't find the info, but i think its bay trail standard.

Thank you so so so so much.

Nice that it works, :) I will include this firmware directly in future releases.

If you post a new dmesg, I will check if a firmware is missing but you are probably affected by the quite common "bluetooth working from command line but not from the settings menu" issue. (#331). ChromeOS r84 is supposed to bring new bluetooth improvements, I hope it will help with this.

Sorry but chromeos only supports usb cameras, even though your cameras might be supported in linux they will not work in chromeos. You can still try with "reef" or "samus" recovery images which are the most compatible for camera but I highly doubt it will change something.

dmesg.txt

heres the new log

Other questions is, its normal for chrome to drain the battery? im using octopus recovery, i feals its more faster than rammus, i will try the others you mentioned

Thanks again @sebanc

[sebanc]

Indeed, you miss a bluetooth firmware but to know which one I would need you to post the output of "lsusb"

No, it is not normal that chromeos would drain battery once the initial install is finished but in your case I don't see what could be draining the battery (usually it is dual gpu).

@sebanc here it comes

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 0bdb:193e Ericsson Business Mobile Networks BV (my 3g module)
Bus 001 Device 004: ID 045e:0745 Microsoft Corp. Nano Transceiver v1.0 for Bluetooth (my usb keyboard and mouse)
Bus 001 Device 003: ID 05e3:0610 Genesys Logic, Inc. 4-port hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

i dont have any other GPU, its a Intel atom one and it seems to be recognized correctly
How see whats draining the battery?

i did a battery test heres the results

battery_test
No test length specified. Defaulting to 300 seconds.
Battery is discharging (11.90% left)
Battery health: 89.93%
Please wait...
Battery discharged 2.17% in 300 second(s).

Could you unzip the below file in your Downloads folder, then run "sudo cp ~/Downloads/BCM.hcd /lib/firmware/brcm/", reboot and see if bluetooth works ?
BCM.zip

For battery drain, octopus is not the best recovery image due to a camera framework issue which increases cpu workload, try "reef" maybe.

Worked instantly again, you ar an magician!!!!
For me you can close the case.

I really appreciate an amazing human like you, help me alot, thanks u so much, hope you have an amazing Sunday !

Please incorporate this files in a next brunch version ;)

[sebanc]

Unfortunately, I cannot add this firmware directly in brunch as the same firmware name is used for significantly different hardware. After each update, you will have to copy this firmware manually.

Have a nice sunday too !
