Last week we ran Apache NuttX Real-Time Operating System (RTOS) on Unicorn Emulator, and we hit a baffling Arm64 Exception in the emulator. In this article we’ll create some tools to troubleshoot the exception…

1.  Render the Dynamic Call Graph for Apache NuttX RTOS, to understand how it boots

2.  Make it Clickable, so we can browse the NuttX Source Code as we explore the Call Graph

3.  We’ll use a Block Execution Hook in Unicorn Emulator to generate the Call Graph with Rust

4.  And call the Rust Libraries addr2line and gimli to map the Code Addresses to NuttX Kernel Functions

5.  Thanks to the (Clickable) Call Graph, we’ll describe the complete Boot Sequence of NuttX RTOS on PinePhone

6.  And explain how we might do Automated Daily Build and Test for NuttX on PinePhone

I would like to reinstall arch with fde via the installer, but it seems to not be working anymore. Is there a fix or a way to do it?

I installed a sloppy porting version, but it is very beautiful. It comes from: [b]https://cloud.189.cn/t/u6BrQbZVnuum[/b]  （Access code  5feb）
I would like to make a DEEPIN OS image based on this, but I will not transplant it,
I hope people with this technology can complete this mission.

Every time my Rock64 boots, I get an error about the Superblock last mount time is in the future. As I don't have a working hardware clock, this happens on every boot, force an fsck and adding to the boot time. When searching for this error, most of the recommendations are to fix the clock, but that isn't really feasible on a device that doesn't have one. Seeing as this check happens before mounting the filesystem, a solution like fake-hwclock isn't likely to be useful either. I can't be the only one with this problem...

Hi all,

For pinebud users out there, how is the voice quality when making calls with these? Is the open firmware any better than the default one that ships in this regard?

Thanks!

HI,

I have a pinephone (not pro) with battery keyboard and last version of postmarketOS.
I didn't noticed any problem at start but after few days, power management in settings app in postmarketOS showed two 'extra batteries' which lead to problems calculating the percentage of charge. (max was 67% instead of 100% when fully charged)
Since two days I now have a third extra battery instead of only one (1 main battery + 3 extra batteries) ... how can I correct this please ?

Thx.

So I recently installed arch https://github.com/dreemurrs-embedded/Pi...g/20230203 on on my Pinephone (not pro), and tried to use the keyboard which was fine except the top row characters ( - _ + = ~ etc), I don't know exactly what i did but it fixed it for me.

I updated my ppkb's firmware to 1.3 here's the guide to update https://xnux.eu/log/#078

I then used the bottom part of this guide https://wiki.mobian-project.org/doku.php...ccessories this part:
Symbol Keys
With the latest version of the keyboard drivers, the Fn-symbol keys disappear. This can be fixed by:

• Setting
  
  Code:

  XKB_DEFAULT_MODEL=ppkb
  in Phosh's environment. Add the following to
  
  Code:

  /usr/lib/systemd/system/phosh.service.d/override.conf
  :
  

• Reboot or restart Phosh.
  

Some time ago I noticed that I no longer hear my peer during a call. After some investigation and trying different images I installed factory test image from here: https://wiki.pine64.org/wiki/PinePhone_P...e_Checking
No sound can be heard during earpiece test even there . So I come to conclusion that Earpiece is not working on my device at all. It was working previously, sadly I cannot confirm exact point when the issue started.
Is there anything I can do with that?

With PP Community/Physical kb/Manajro Phosh Beta 29, I have a grayed-out Alarm-or-Bell icon next to the battery icon. Is there any way to remove that? I don't use the PP for any alarms.

Thanks.

hello dear unixoid friends. I recently purchased a keyboard. I'm testing with the factory assembly of Manjaro with kde plasma.

In kde plasma mobile in the settings there is the ability to enable various language layouts only for the on-screen keyboard.

There are no settings as such for the hardware keyboard in the graphical interface.

Please tell me, do not refuse the beginner, how can I not only add a second language layout, but also assign switching keys.
