Linux Tablet?

Axios

BuzzPCSOS Do you have a dir of (/sys/bus/sdio/devices/) and if you do is anything
listed.

BuzzPCSOS

Axios Yes there are three folders.
mmc1:0001:1
mmc1:0001:2
mmc1:0001:3
Each folder has 3 folders and 10 files which look very similar to the content of the other two folders.
Much of it looks like it gets updated at boot.

Axios

BuzzPCSOS Unplug your realtek usb dongle and run wifi-info again
(Just to try and cleanup the listing to tell easier whats going on)
look at Networkmanager info section and see if the broadcom is listed then

This is the file I am comparing it to
https://ubuntuforums.org/showthread.php?t=2329846&page=3
Appears to me things are not ini right or loading or something
That whole thread is interesting reading you may pick up on something I havent
(correct me if wrong)

From this error in dmesg (this is issue but not sure its causing your problems)
brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50

Axios I did run the script without the USB dongle inserted. I am guessing the script picks up from some logs already stored on the device which is a shame because I needed the WiF dongle to install in the first place.
Not got access to the Linx at the moment but will try booting without the dongle and see if that cleans anything up at all.

Edit:
I have changed the output from Wireless-info that I posted above to the revised version where I booted without a wireless dongle. It looks similar to the text dump you were comparing it to. I had a go at working out what my next move needed to be but got a little lost.
The first suggested command that seems to give a valid output is ls /sys/bus/platform/drivers/sdhci-acpi/ which returned 80860F14:00 80860F14:02 80860F14:03 bind module uevent unbind

Axios

BuzzPCSOS No (mac80211) Module loaded-Also noticed no rfkill for wifi just blue tooth
Makes more sense now
and errors in Dmesg
14.633357] brcmfmac mmc2:0001:1: Direct firmware load for brcm/brcmfmac43455-sdio.LINX-LINX12X64.bin failed with error -2
[ 14.671136] brcmfmac mmc2:0001:1: Direct firmware load for brcm/brcmfmac43455-sdio.txt failed with error -2

There is no (mmc2:0001:1) in that dir listing I had you do earlier

(Just thinking outloud)

The Linux kernel is trying to load firmware from a file under /lib/firmware to install it in to the device and not finding it. (In these cases this usually needs to be done every time the device is initialized.) The path given in the error message is relative to /lib/firmware; you need to find the correct firmware and put it in that file.

If this is the case but why?
In the files you copy to firmware was there a .Blob?

BuzzPCSOS

Axios Most of what you have got there is over my head I'm afraid but I guess the answer to your last question is cheap mass produced electronics. These tablets came out with similar (but not as good) performance to the MS Surface tablets of the same era but at a fraction of the cost. History shows that operation on the software they were shipped with was the only surefire guaranteed choice. Updates frequently left them crippled.
The fact that as many features work at all in 2024 is a miracle in itself.
I'm not sure how many more rabbits you can pull out of the hat but your efforts are much appreciated.

Axios

BuzzPCSOS Ya and the rage tablets where for awhile then poof kinda fell off cliff

BuzzPCSOS

Axios I can kind of see why, Android and Apple phones are a very specialised version of Linux that run on very low power hardware. To get a reasonable experience on a PC tablet you need to run quite powerful CPU and GPU which then means that you either need big batteries (heavy and thick) or to make a sacrifice to run time (not very practical). We have all been taught to expect a tablet that is slim, light, shiny and sexy with a battery that lasts all day but for the most part a laptop CPU can't return that.
This Linx tablet lasts for hours and hours even on an old, well used battery. Performance is low and the CPU lacks many of the clever instruction sets that it's powerful cousins have. Some programs take an unnecessary amount of time to execute because of that.
I was looking for PC features rather than PC speed and have the time to wait for things to happen. This little tablet has been a good introduction into the Linux Tablet computing experience. Now most things are installed and set up I really don't need to access the single USB port half as much as I thought I would so my wireless dongle has been mostly undisturbed.
Perhaps sometime in the future I will take a look at the suggestions made by @inkbug or explore a more upmarket Atom based tablet than the Linx. The Dell Venue range looks promising although my choices are a little limited if I insist on 4Gb of ram or more.
Thank you very much for your help. I have learned a lot on the way but I can't see a viable fix being found for the wireless. I think the Linux way of providing one driver for many just does not work here as the hardware is just too picky.

Axios

The last info you provided was very helpful I can see maybe whats happening but at this point
I cant say why.
So Many variables to Linux hard keep them straight sometimes at least for me.
I got get back to R/L for awhile was under weather so had sometime to kill.
Only other thing I can suggest maybe try distros till one works (Not my first choice and time consuming)
Agree with what you said and its hard when manufactures cut corners they cause problems like this.

Kinda like my asus tab it had such uncommon camera there was no way period to make it work and I dont write
software anyways for what it was wasnt worth the effort.
Am at point got clear my mind..lol

BuzzPCSOS

Axios good call. It has 4Gb of ram and is x64 so I can afford to mix it up a bit. Might try Ubuntu and Mint and see if I get lucky. I chose Manjero because four years ago most stuff worked on that. Everything changes I guess.
Again many thanks for your help and support. Really appreciated.

Axios

BuzzPCSOS Oh I forgot (One last thing) I know the commands for eopkg and dpkg to list installed packages for certain
things lets say (broadcom) or (intel) and it will show those.
But not having much luck with pacman but they do have a (pacman log viewer app)
not sure it will do it think it will.
Below is kinda what I am looking for show all installed for broadcom.

No big hurry just curious

BuzzPCSOS

Axios Not sure but I think Pacman has been depreciated in favour of Pamac, anyhow here is the broadcom software list.

Axios

BuzzPCSOS Thanks

I ran across this (NOT GOING SAY ITS A GOOD IDEA OR BAD) but we all know what can happen
(bricked computer) Leave that choice to you.
Downloaded file and took gander at it there is a readme.
What he talks about is quite interesting. (And I think we prob already knew some of it)
https://www.css-networks.com/2020/09/linx-12x64-tablet-pc-cameras-not-working-bios-settings-kaput-etc/

I think if I did it and it worked I would start fresh manjaro or whatever (without those added wifi drivers) and
see what happens.
(Just info) would check your current bios date

BuzzPCSOS

Axios Good call!! Already found the bios update and checked that I was on the the last revision released by Linx.
When you boot into the bios the touchscreen is not functional and the usual key presses are not available to choose your boot media so a USB hub, keyboard and mouse are required to install anything. Worse than that - if the drive is wiped (all 64Gb of it) Windows will not be able to find drivers for WiFi, battery state and about half a dozen other essentials from a clean install. I think some owners thought the fix might be to return the bios to default values. Bad move, the stock bios was a wide open generic bit of code with hundreds of potentially lethal combinations.
Linx eventually updated the bios to fix all of that stuff and supposedly improve the WiFi performance.
When you clean install into Windows it is still mostly broken unless you have access to the specific drivers published by Linx. I managed to get most things working but could not make battery status load. Even then Windows 10 on a 64Gb hard drive left very little room to do anything else with and any updates were mostly not installable without serious pruning and data offloading. Basically a tablet ideally suited to a Linux system.

Axios

BuzzPCSOS I dug around and charged my asus earlier
and I have no comment..lol
It uses BCM43241 WLAN card so much is famialar with what you posted about yours.
Have you ever tried this
#unload brcmfmac
modprobe -r brcmfmac
#reload brcmfmac
modprobe brcmfmac
will see if something jumps out lotta crap to look at..
Oh its fedora and am posting with it

Mine shows up as a usb device even tho its sdio interesting

BuzzPCSOS

Axios Not much happened, or did I miss something?

Pretty sure I removed the original drivers that I tried which may/may not make a difference.
I have downloaded the latest desktop version of Ubuntu today and got it all written to a stick. I will try a live run on that tomorrow when I have access to a USB hub, keyboard and mouse. I will see where I go from there and what works and what doesn't. Now I know what to look for I might just find a distro that has it all straight out of the box.

BuzzPCSOS

Ubuntu and Mint were a bit of a disappointment on the Linx, WiFi was not working, touchscreen was not directly available and various other features did not work. I am sure all this could be made to work but fiddling about with a keyboard, memory stick, WiFi adapter, mouse and a USB hub all running out of one USB port is slow and unreliable.
I have a suspicion that the wireless broke with kernel updates as earlier versions all boasted some level of connectivity which broke after updating.
Everything works very well (but slowly) from a fresh install of Manjero apart from the wireless which works nicely on a faster USB dongle so could be thought of as an upgrade.
I have fresh installed Manjero because I was beginning to loose track of what was really broken and what had been broken due to overzealous tweaking.

Axios

BuzzPCSOS Found this might be worth checking
That should be all that is needed to get SDIO working. Linux will automatically poll the SDIO port once every second. Any devices that enumerate will appear in the sysfs folder /sys/bus/sdio. Provided Linux has the correct driver, and the driver has a compatibility string that matches the vendor and device IDs in /sys/bus/sdio, everything should Just Work.
Might let us know if its seeing the wifi correctly
I havent looked on my asus to see what it has.

I routinely use Bluetooth to operate my Samsung phone. I have a mouse and keyboard that pair with three different devices, so #1 is my laptop, #2 is the TV streaming computer across the living room, and #3 is my smartphone, on a stand in front of my chair. I only use its USB-C port for charging.

Is there any chance that Bluetooth could help simplify your problems with multiple USB devices?

BuzzPCSOS

Axios Inside the/sys/bus/sdio are 3 files and two folders.
drivers_autoprobe is empty, drivers_probe and uevent are locked but also appear to be empty.
The devices folder has three sub folders marked mmc1:001:# the contents looks like dummy files to me.
The drivers folder has two sub folders brcmfmac and btsdio. The btsdio folder has what looks like 3 empty dummy files in it. The brcmfmac folder contains a module folder which looks like it contains a lot.
What am I looking for here?

BuzzPCSOS

WetGeek I already use a Bluetooth mouse and am looking at various options for Bluetooth keyboards. Unfortunately external drives are where my heaviest external traffic is,
Also my tablet does not work with Bluetooth at bios level which is where I would want the most connections to peripherals.

Axios

BuzzPCSOS Ah ok it works like posted earlier looks like its not enumerating properly
so kernel or driver
Here is mine you got have the mmc folders the mmc in the driver folders will have alot in it (its the second screen shot)
if you dont have it wont work

Once its creating the mmc stuff properly it should work
Will press on later. (No Worries I love this stuff gives me something to do)
It enumerates the device first then the driver from what you said its seeing the device let me know what the driver folder
looks likes the mmc
If it turns out not looking like that its a driver issue but gives you a point of reference when trying drivers which is a big step in telling if stuff is loading properly.
