Hello I made my SDHC sard working by changing sdcard from ACPI mode to PCI in bios under bridges settings :) try it yourself

aminehmida commented 7 years ago

@crackgm thanks for sharing ❤️ I hope that someone will be able to fix the remaining problems too (Speekers, cameras and accelerometer)

pgrobelny commented 7 years ago

did you get it working too?

danielotero commented 7 years ago

Thank you for sharing it! As soon as I test it, I will let you know if it works for me.

If you feel like contributing in some way, don't hesitate to ask for write permission, as I don't have much time to fiddle with the device by myself.

My BIOS is awfully detailed. Do you mean the settings under Chipset/South Bridge/LPSS & SCC Configuration/SCC SD Card Support?

If I change it to PCI Mode the card does not even shows on the kernel log. In ACPI mode at least I get:

error: -110 whilst initialising SD card

Do we have the same device? Mine is a Chuwi Hi10 Pro Z8350 S/N HQ64G4217010xxxx

pgrobelny commented 7 years ago

The same tablet. Maybe kernel? I use antergos with newest kernel

As I noted in a different issue, the microSD slot worked right away for me.

S/N is HQ64G421703XXXXX Bios settings are default (It keeps resetting on me); Dualboot with windows using efistub and rEFInd (though the bios has serious issues actually doing what it's supposed to and not messing up the bootorder every other boot)

danielotero commented 7 years ago

I'm using the kernel config that is published in this repo. I should try with the stock one (but I think the brightness setting wasn't yet fixed) and with different SDCards, as maybe some other chip works.

Also, I can't get rid of the preloaded bootloader that came in the device (the white one that let me choose between Windows and Android, before I clean all the eMMC storage), and I have to load Arch through the Android option before I reach the gummiboot efi loader. Maybe that issue is affecting the BIOS settings in some way. I should study that.

There are a couple of differences. I wonder if it has anything to do with it...

Orochimarufan commented 7 years ago

You can disable the built in boot menu from Windows by using the SwitchNOW app and selecting No in the promt that asks to switch to Android. Unfortunately it comes back sometimes. That BIOS has some serious voodoo included that tries to fix broken boot setups, conversely it breaks stuff all the time if your setup doesn't match what it expects :(

The bios and board rev are different. Now that I look at it, we also fall into a different bracket in the official downloads thread: http://forum.chuwi.com/thread-2341-1-1.html yours falls into 2) while mine is 3). Unfortunately they don't provide bios updates for the hi10 pro and it's not particularly safe to flash a bios that came with a different board rev.

pgrobelny commented 7 years ago

Just to let you know, my sdcard is working but once 2-3 reboots it behaves like it doesn't exist.

Orochimarufan commented 7 years ago

A small update on my part: My SD card has been acting up a lot recently. The symptoms are similar to others described here, but I believe it's more of a case of flaky hardware than a Linux issue because I've since experienced similar problems in Windows, though I'm not entirely sure there since Windows error reporting sucks. When it's gone in windows, the event log entry just says there was a paging error detected related to harddisk1. I've also noticed occasional severe slowdowns in both OSes that seem to be the system trying to deal with the SD card.

Danct12 commented 5 years ago

Android detects my card just fine, however on Linux it'll just failed to initialize.

RafaelLinux commented 3 years ago

It's a hardware issue. Even on Windows 10 and Android, mSD reader fails, and no way to read mSD cards. Android ask to format and format (after accepting) forever, and Windows 10 (native default version) doesn't recognize any card. So Chuwi is the bug, not any os.

Danct12 commented 3 years ago

I noticed that too, I haven't gone back to my tablet since I got my Pinebook Pro.

But it seems to be a common issue as well, someone I know ran into the issue and it was also discussed on russian forum boards.
