Arch on Bay Trail Tablet cannot find Sdcard

Hello fellow Archers!! smile I am new to the Arch Linux Forums (or any forum for that matter), and I hope I've put this post in the proper place.

I've been using Arch for about 2 years now, and I'm absolutely in love with it. Every chance I get, I try to run Arch on any device I have. This last Christmas, I received a Toshiba Encore Mini (Bay Trail) tablet from my stepdad and when I found out that it had an x86 processor, my heart skipped a beat. I knew what had to be done. smile

After a month of research and fun, I have successfully been able to boot Arch on this tablet. I am using the stock 3.18.5-1 kernel (latest as of this post) and GRUB for the bootloader. Arch currently resides on a USB stick, and I've been able to move GRUB into the EFI system partition on the internal memory of the tablet. I've setup GRUB to be able to dual boot Windows and Arch, but of course the Arch entry only works when I have the stick plugged in.

Although I've been successful, I've still had some issues. The internal memory in the tab is 14GB, 4GB of which belongs to the Windows recovery partition. I'd love to be able to boot Arch on this tab without having to plug in the stick through OTG, as it is susceptible to damage and prevents me from being able to charge, but 10GB total space is not really optimal for what I want to use this tablet for. Luckily, there's an external microSD slot on the side. I bought a 32GB microSD to put in there and I wanted to make it my /home partition. Alas, when I booted into Arch and got ready to add the card to my fstab, it wasn't there! Here's the output of lsblk, lspci, and lsusb:

https://dl.dropboxusercontent.com/u/989 … 094036.jpg

sda is the USB stick and mmcblk0 is the internal memory. The PNY in lsusb is the USB stick as well, the Logitech Unifying Receiver is my wireless keyboard/mouse, and the Genesys device is my USB hub.
I checked GRUB as well, and at the GRUB shell, ls turns up with:

(hd0) (hd0,msdos2) (hd0,msdos1) (hd1) (hd1,gpt4) (hd1,gpt3) (hd1,gpt2) (hd1,gpt1) (hd2) (hd3)

hd2 and hd3 are blank and GRUB won't let me set them as root. I have also formatted and used the microSd card before in Windows, so I believe it should at least show up with a partition, so I don't think hd2 or hd3 could be the card.

So, my question is, what should I do to get my sdcard recognized by the tablet? Windows sees it just fine, even in Win10 Technical Preview.
The tablet is a Bay Trail device and uses only 32-bit UEFI for booting. It has no BIOS/CSM support. Along with the PCI bus it sports an i2c bus and an sdio bus. My guess is that it has something to do with GRUB or the UEFI firmware, but I decided it would be better to ask some experts.
Any help would be dearly appreciated! And thank you for your time!

Re: Arch on Bay Trail Tablet cannot find Sdcard

Nice fingers smile

This mmcblk0 seems to be an eMMC, which must be connected to some MMC/SD controller. Since there is none visible on PCI and USB, I suppose it must be a "platform" device - integrated on the Bay Trail SoC, not enumerated on any bus, accessible only through "well-known" (to those who know) memory-mapped registers. I guess there's another one driving an SDIO wireless card (no PCI or USB WiFi) and another one driving this microSD slot.

It's weird that only the internal eMMC is seen. Did you try hotpluging SD when Linux is running? Can you paste dmesg output (save it to a file, it won't fit on one pic smile)?

In older versions of Windows, one could open "properties" of "this computer" and click "device manager" to get a list of all devices known to Windows. Does it still work? This list could be sorted by bus connection ("view" menu, I guess) so it should be possible to find out where all these MMC/SD/SDIO controllers are.

Re: Arch on Bay Trail Tablet cannot find Sdcard

Thanks for your reply. smile And you are absolutely right, the wireless card is SDIO. It happens to be a Realtek RTL8723BS.

Here's the dmesg output:

Re: Arch on Bay Trail Tablet cannot find Sdcard

So we have

and

[    2.845111] mmc1: new high speed SDIO card at address 0001

I guess it's this "failed to setup card detect gpio", which means that the SDHCI driver is buggy or not prepared to handle some hardware bug. As a quick and lazy workaround, you can try booting with card removed or using the LTS kernel.

EDIT:
Similar issue, it seems that kernel recompilation with different config was needed. Have fun smile

Re: Arch on Bay Trail Tablet cannot find Sdcard

Booting without the card in does nothing. The same errors show up in dmesg with or without the card, which leads me to believe it might be the bus itself. If I plug the card back in at this point, nothing is added to dmesg.
After that, I added the LTS kernel and changed the GRUB config to boot it.
When I booted, it still couldn't find the card. In the new dmesg, however, the "failed to setup card detect gpio" is replaced by "failed to setup card detect wake up" and the warnings about "No regulator found" are gone.

I will take a look at the post you linked. Thanks for all your help! I'll post more when I find out something new. smile

Re: Arch on Bay Trail Tablet cannot find Sdcard

This CONFIG_PINCTRL_BAYTRAIL looks very plausible. It's a low level GPIO driver so I bet distributions disable it due to clashes with ACPI on some machines and now, other devices which actually need it, don't work.

Re: Arch on Bay Trail Tablet cannot find Sdcard

Same here !!

I got my teclast x80h yesterday. I have been able to boot into arch despite the shitty 32bit uefi.
because tf slot is not recognized and unbootable, I have to use usb hub for keyboard, flash drive & wifi dongle.
I can't charge the tablet if the usb port is occupied. And my previous plan to use tf slot and bluetooth keyboard went into toilet.
a working rtl8723bs is more urgent. I can always destroy windows partition.

btw, I'm using framebuffer right now. It's wired intel graphic isn't working.
touchscreen, camera, light sensor and other fancy stuff isn't working. (at least for now)

Re: Arch on Bay Trail Tablet cannot find Sdcard

Okay, this solve the sd/mmc reader problem.

CONFIG_PINCTRL_BAYTRAIL=y

I'm using linux-uksm-ck 3.18.6. I guess any 3.18 kernel would work.
this is what lsblk will look like now:

NAME         MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
mmcblk0rpmb  179:24   0    4M  0 disk
mmcblk0boot0 179:8    0    4M  1 disk
mmcblk0boot1 179:16   0    4M  1 disk
mmcblk0      179:0    0 29.1G  0 disk
├─mmcblk0p1  179:1    0  100M  0 part
├─mmcblk0p2  179:2    0  128M  0 part
├─mmcblk0p3  179:3    0 23.4G  0 part
└─mmcblk0p4  179:4    0  5.5G  0 part
mmcblk1      179:32   0 14.9G  0 disk
├─mmcblk1p1  179:33   0  150M  0 part
└─mmcblk1p2  179:34   0 14.7G  0 part /

after compile the custom kernel. (CONFIG_PINCTRL_BAYTRAIL=y)
modprobe r8723bs give us

wlan0     unassociated  Nickname:"<WIFI@REALTEK>"
          Mode:Managed  Frequency=2.412 GHz  Access Point: Not-Associated   
          Sensitivity:0/0

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

But unfortunately, wpa supplicant doesn't work.
DSC05539.jpg
I can't see any blutooth device either.
hciconfig -a shows nothing.

I still have problem with intel graphic.
I need nomodeset kernel parameter to prevent blank screen.
but I guess it also prevent dri from loading.

Re: Arch on Bay Trail Tablet cannot find Sdcard

Bluetooth probably is integrated with WiFi. You may want to verify this with Windows Device Manager. If this is the case, you'll just need to find drivers. Maybe there are none.

Whatever issue you have with video, it's probably unrelated with this thread.

Glad to see that someone else is just as interested in this kind of project as I am! big_smile

It looks like our tablets have basically the same hardware, boteium. We might be able to help each other out. I have found that https://github.com/hadess/rtl8723bs works for me with the stock Arch kernel. Here's what I did for reference:

git clone https://github.com/hadess/rtl8723bs.git
cd rtl8723bs/
make
sudo make install
sudo depmod -a
sudo modprobe r8723bs

Currently, I've been having trouble compiling a kernel because most of my devices are old and it takes a very long time for them to compile a kernel. As a temporary workaround, I have had some luck with Adam Williamson's fedlet kernel, although I had to alter my mkinitcpio configuration for it to enable my USB keyboard. The fedlet kernel gives me access to my sdcard, which is nice, but it desn't really do much else that the stock Arch kernel can't do.

RIght now my main obstacle is the battery. I have no intention of completing my full install onto the tab if I can't check my battery levels. However, when it comes to ACPI and all of that, I have no clue how to start. I know that the battery in Windows is known as PNP0C0A, and in Arch there is a /sys/class/power_supply/BMBT and /sys/class/power_supply/ADP1. acpi returns

Battery 0: Unknown, 0%, rate information unavailable

Any help would be appreciated, and thank you so much mich41 for all your help so far. smile

Re: Arch on Bay Trail Tablet cannot find Sdcard

I can confirm that the driver I linked in the previous post works with my own kernel build with CONFIG_PINCTRL_BAYTRAIL=y, along with the sdcard being recognized. I used the .config from the stock Arch 3.18.6-1 kernel and only added CONFIG_PINCTRL_BAYTRAIL=y before building. Hope this helps you, boteium. smile I'm going to let my tab charge for now before I try and get the battery working.

Re: Arch on Bay Trail Tablet cannot find Sdcard

So, do you have any files in /sys/class/power_supply/BMBT  ?

Re: Arch on Bay Trail Tablet cannot find Sdcard

I'm also using hadess' driver. It somehow work on kernel 3.19.
although I'm experiencing random disconnect and kernel panic.
I don't have anything in /sys/class/power_supply. ( Did I misconfigure  my kernel ? )
It turns out i915 is working despite the blank screen. I am able to unblank it using xrandr.
I also tried CONFIG_SND_SOC_INTEL_BAYTRAIL=m .
There are a lots of modules like snd-intel-sst loaded on my tablet now, but alsa sees nothing.

What is the bitness of the kernel you are booting with? What you said here leads me to believe that you might be using a 64-bit kernel, which could be the source of your problems. I have had a bunch of trouble with getting a 64-bit kernel running smoothly, so I've been sticking with a 32-bit kernel and I've had very few problems. Also, most of the drivers for bay trail devices - including open source ones - have only 32-bit support, so running 64-bit would just cause problems later on.

Yes. It has the same files as a normal battery would have (i.e. my laptop). However, capacity is always 100 and many of the others are unknown. I've tried this patch but it does nothing.

Re: Arch on Bay Trail Tablet cannot find Sdcard

Yes. I'm using x86_64 kernel.
I tried a lots of different kernel config and non of them work.
for example,  CONFIG_ACPI_I2C_OPREGION=y kills emmc & tf reader altogether.
I also tried arch stock kernel's config with CONFIG_PINCTRL_BAYTRAIL=m.
there's nothing in /sys/class/power_supply/.

I guess fedlet is using CONFIG_ACPI_I2C_OPREGION and CONFIG_ACPI_CUSTOM_DSDT with asus t100 dsdt patch.
AlbinoJawa, does alsa work on your device ?

Re: Arch on Bay Trail Tablet cannot find Sdcard

No, ALSA is not working on my device. When I try to launch alsamixer, it says "cannot open mixer: No such file or directory".
I do know that on our devices, the speaker and microphone are connected on the I²S bus, but I am not seeing any such bus under /sys/class/ or /sys/bus/. I will do a bit more research while at school today and see if I can find a kernel module or at least some info on the I²S bus. All I do know about it is that it isn't related to I²C.

Re: Arch on Bay Trail Tablet cannot find Sdcard

I would recommend trying CONFIG_SND_SOC_INTEL_BAYTRAIL=m .
although It's not working on my device, I got some error message of these modules in dmesg output.

I know that asus t100ta does use acpi i2c operation region to access battery information. but I can't find any information about what kernel modules it is using. I'm trying different configuration blindly now.

Re: Arch on Bay Trail Tablet cannot find Sdcard

I've started a compile since I got home. I added CONFIG_SND_SOC_INTEL_BAYTRAIL and CONFIG_SND_SOC to my config. In about an hour, I should be able to test it and I'll post my results. If that turns out well, I'll begin working with CONFIG_ACPI_I2C_OPREGION.

EDIT: No luck. Building the kernel with that config made mkinitcpio not want to put any modules into the initramfs.

Re: Arch on Bay Trail Tablet cannot find Sdcard

This is what I found recently :

CONFIG_ACPI_I2C_OPREGION causes a lots of problem on kernel 3.19/3.18. Some modules fail. Some build won't even boot.

CONFIG_ACPI_I2C_OPREGION & CONFIG_PWM_LPSS on linux-next-git (20150213) gives me the same result as AlbinoJawa said.
capacity in BMBT folder is always 100.

How did you install the kernel? It sounds like mkinitcpio looks for modules for wrong version.
