  How to determine the cause of a crash? Anything like syslog, dmesg in var/log/?
Posted by: Anna - 03-16-2021, 11:25 AM - Forum: Mobian on PinePhone - Replies (4)

My Pinephone crashes about five to ten times a day without any obvious cause. (Is that normal, by the way?)

In var/log/ are none of the log files (like syslog or dmesg) usually recommended as a source of information when experiencing crashes.

Are there any other files (maybe in some other directory) that I could check in order to determine the number and causes of crashes?


  What do the buttons do?
Posted by: kiriakos - 03-16-2021, 05:23 AM - Forum: General Discussion on ROCK64 - Replies (1)

So my Rock64 has three physical buttons in it. Two of them are located on the edge of the emmc side and one is located north of the emmc space. I have tried searching around at their function but could only find some info regarding Rock64 running Android. The Board details page says they are Power, Reset and Recovery buttons but other than resetting the board I could not find out how the power or recovery functions are accessed or what "recovery" would mean for my system (archlinuxarm UBoot).

Context, I run archlinuxarm with the UBoot bootloader.

If anybody has more info regarding these buttons I would be happy to know what they do and if/how they could be programmed. :-)


  Block Phone Numbers?
Posted by: MarkF - 03-16-2021, 05:22 AM - Forum: Mobian on PinePhone - Replies (6)

Hello All,

Apologies if this has been answered before but I couldn’t find a post on this.  Is it possible to block phone numbers on Mobian?  I’ve looked in the obvious places but I can’t find a way to do it.

Many thanks.


  Issues with Mobian 20210314 (data and updates)
Posted by: IMSAI8080 - 03-16-2021, 03:20 AM - Forum: Mobian on PinePhone - Replies (5)

Hello,

used for a while Plasma KDE (still too buggy, for me) and Phosh OS (working fine) and now decided to give Mobian (20210314) a try (on this forum, it is highly appreciated). So, flashed a SD with it. 
Unfortunately, data download never started working (although, I have the 4G symbol activated and four bars). Of course, set the APN.
Calling works fine, SMS works (but no audio signal and light blinking when I got the message) and WI-FI works as well but, oddly, using it, my phone is unable to download updates ("The following packages have unmet dependencies").

Any help for the two issues?

Many thanks.


  Pinephone - broken power button
Posted by: rorus - 03-16-2021, 02:58 AM - Forum: PinePhone Hardware - Replies (13)

So, I have been using my Pinephone, in a wallet case not designed for it, on a temporary basis. Was working well, but had to pop the Pinephone out of the case to press the power button.

Suddenly, a very soft "ping". The little dish-shaped aluminium plate came off the power button, revealing the two contacts (the inner copper dot and outer copper ring).

Power button still works if I short across the contacts with a conductive object.

Fixing the little aluminium plate back in place with a touch of cyanoacrylate glue did not restore the power button's function, had to remove it again.

Spoke to a friend we all call "MacGyver", he doesn't like even his chances of repairing a little momentary power button, says he's succeeded twice on about fifty devices attempted.

I need a replacement power button for the Pinephone. I've searched the datasheets and component list hoping for a component ID for the little momentary power button, but it only lists the larger modules.

Does anyone know what a suitable replacement button would be? Digikey component number or a link to eBay / Aliexpress would be most welcome!


  Selling Pinebook Pro 128GB version (w/ NVMe adaptor) due to lack of use
Posted by: VoT - 03-16-2021, 01:54 AM - Forum: General Discussion on Pinebook Pro - Replies (3)

Hi All,

I just wondered if there was anyone out there wanting to buy my Pinebook Pro?
It is one of the original 1000 from the community batch, released after the initial testers batch.

It all works fine, and includes the NVMe adaptor (not yet fitted).
The reason I am selling it is because I've been simply too busy to use it. My total use of it has been to format a few SD cards, watch 3 movies on it and used it to backup a hard drive to a different hard drive. That's it!

I am in the UK but the power cord has a 2 pin plug as standard. I just used an adaptor and can include one when I send it if needed, 
I would prefer to ship to the UK as it'll be cheaper and easier but I could be open to sending abroad (I'd need to look into costs).
The buyer would need to cover shipping.

If you're interested, please send me a message or reply on the thread.

Thanks
VoT  Smile

  Write to an A1-rated Micro SD card failed
Posted by: dsimic - 03-15-2021, 08:52 PM - Forum: Pinebook Pro Hardware and Accessories - Replies (12)

Hello,

While attempting to perform a performance comparison of A1-rated and non-A1-rated Micro SD cards, with additonal emphasis on using F2FS instead of ext4, I've encountered a major issue with the PineBook Pro's SD card interface.  Here are more details.

In a few words, attempting to write about 14.5 GiB to a Kingston A1-rated 16 GB UHS-I Micro SD card (SDCS2/16GB) resulted in a failure and the following Linux kernel messages, after writing about 700 MiB to the card:

Code:

This happened two times in a row, which makes the issue very easily reproducible.  Unfortunately, it also caused the Linux kernel to become locked up on shutdown, requiring the laptop to be forcedly powered off.

Here are the kernel messages upon inserting the A1-rated card:

Code:
[ 1777.728204] mmc_host mmc1: Bus speed (slot 0) = 400000Hz (slot req 400000Hz, actual 400000HZ div = 0)
[ 1777.881900] mmc_host mmc1: Bus speed (slot 0) = 148500000Hz (slot req 150000000Hz, actual 148500000HZ div = 0)

[ 1778.179620] mmcblk1: mmc1:5048 SD16G 14.4 GiB
[ 1778.189478]  mmcblk1: p1

For reference, here are also the kernel messaged upon inserting a 16 GB UHS-I Micro SD card that is not A1-rated (Kingston SDCS/16GB):

Code:
[   56.649797] mmc_host mmc1: Bus speed (slot 0) = 148500000Hz (slot req 150000000Hz, actual 148500000HZ div = 0)
[   57.093248] dwmmc_rockchip fe320000.mmc: Successfully tuned phase to 97
[   57.093339] mmc1: new ultra high speed SDR104 SDHC card at address 1234
[   57.095057] mmcblk1: mmc1:1234 SA16G 14.5 GiB
[   57.103859]  mmcblk1: p1 p2

The card that is not A1-rated works perfectly.  As perfectly as it can be expected from a Micro SD card, of course. Cool

D'oh!  My first thoughts were that I got a bad A1-rated card.  Though, testing another A1-rated card (another sample of SDCS2/16GB) resulted in the same issue.  Time to try another approach; I wrote the same 14.5 GiB to the first A1-rated card using an external multi-format USB 3.0 card reader (Kingston FCR-HS3), and the write operation completed without errors.  Another write attempt, now using an el-cheapo, generic USB 2.0 Micro-SD-only card reader, resulted in no errors as well.

As a note, the write to the A1-rated card was about 30% slower (7.5 MB/s vs. 10.5 MB/s, as printed by dd) using the USB 2.0 card reader, compared with using the USB 3.0 card reader on the same upstream USB 3.0 port.  That's curious, but I'd need to test with a better USB 2.0 card reader before drawing any conclusions.

So, there is some good and some bad news.  The good news is that my A1-rated cards are fine (I was already prepared to blame Kingston!), and the bad news is that some problems exist in the Linux kernel driver for the Micro SD card interface in the PineBook Pro; it's pretty much safe to assume that the actual Micro SD card interface hardware is not the culprit.

I'm looking into the source of the Linux kernel driver, and I'll post my findings here.  Things don't look great, there are more than a few "this hardcoded value should be safe for all SoC implementations" points in the driver.  Though, those "safe" values could be tweaked and tested.

In the meantime, if anyone else has experienced the same or similar issues, please comment here.


  How can I take readings from the gyroscope and accelerometer?
Posted by: kk22 - 03-15-2021, 06:12 PM - Forum: PinePhone Software - Replies (3)

I would like to use my Pinephone in a project where I need to take gyroscope and accelerometer readings. I can't find any information on how to access these sensors though. I tried lm-sensors but it only displays battery status and thermal sensors. There doesn't seem to be any info on the wiki either about accessing these. How can I log readings from these sensors?


  Will It Be Okay To Order The PineBook Pro US Version For Use In The UK?
Posted by: ImmyChan - 03-15-2021, 02:05 PM - Forum: General Discussion on Pinebook Pro - Replies (7)

Hi

Is it okay to order the US version of the PineBook Pro for use in the UK? The different keyboard layout doesn't bother me, I just wanted to know if there's anything else I should be aware of? For instance maybe voltage issues?

Thanks
