Hello Community!

Don't know if this is the right forum for this question...

Why have UART_RBR, UART_THR and UART_DLL the same offset? Currently I have
not found the reason. There another registers which shares the same offset.


Why I need this information?

First of all, I bought this good piece of hardware for my own embedded HW/SW projects.
Want to use it for Bare-Metal projects (no Linux or *BSD), only currently U-Boot as loader
for my own RTOS (still under development but currently only for the purpose of education).

Greetings all.

I love SBCs and have more than two dozen of the more popular boards. Raspberry Pi? Never a problem until the RPi 4 came out but finally got past that. Some Odroids (the XU-4) can be a pain if power supply and cable aren't absolutely perfect. LePotato worked flawlessly since day 1, as have my OrangePi, Cubie2 and Pine 64.

Enter the RockPro64. I've regretted buying it. Ran once, surprisingly after such a looong boot. Ran for a while. Then I tried an Ubuntu SD and haven't been able to boot up since. Red led, green led, sometime a white one, sometimes not, such a headache. Emmc/SD/SPI interaction confusion. Very surprising and disappointing coming from Pine!

It is clear to me the product was not ready for release at the time I bought mine (early on). I am tempted to buy a new fresh one but for $60+? Not nowadays...

Haven't had such a lousy experience since buying and fighting with my two Parallella boards! Over $200.

Just unpacked the shiny new laptop, it's charged up and the power light goes green when powered on but the screen remains off. Nothin. Black.

Suggestions?

Hello,

I was on this page: https://store.pine64.org/?product=pineph...smartphone
To buy the pinephone, but there is no more stock.
Will it be available again? If yes, when?
Thank you for your answers.
Cordially.

Am thwarted when setup asks for my local. Have no idea how to respond.

I was deleting something from the computer and accidentally deleted an important folder in root.  When I tried restarting, the computer turns on but the screen is black.  I want to reflash the laptop with the Manjaro OS again so I can start over but don't know how to do that.  Any guide?

Hi , is there a way to replace the display panel on Pinebook 11.6'' and if there is the possibility where can I buy it?

Thanks.

So to preface, I originally thought this device was amazing. Decent build quality and other than the factory somehow defaulting wifi to off, I thought it was good!

My first mistake was trying to install anything other than what was on the emmc already. I tried manjaro-xfce and the wifi wasn't detected - at all. When I plugged in a usb wifi adapter to update the installation, it refused to boot after the update. I went through the process twice, same result.

After that, it was an endless slog. Did I mention that there's no eject on the sdcard reader? Is that intentional? Am I supposed to have to find a flat screwdriver to get my sdcard out every time? I did try USB (since I think I read that's supported), but it wouldn't boot from that on either port.

I tried again, with the original KDE manjaro "supported release". I tried three different sdcards, two computers and four different programs/methods to write the images. Every time, it either wouldn't boot, booted into read-only mode or I got endless loops of "authentication failure" when trying to boot and start the installer. I tried mrfixit's version and then used manjaro-arm-installer too. I even tried dd-ing from the SD card when I could actually convince it to start. No go.

After a while I managed to get the manjaro i3 version to install AND have wifi (victory), but I don't WANT to use i3, so I updated and installed XFCE. Fine. Then I rebooted, or tried to. Wouldn't power on. Read up on the wiki, and figured the emmc was loose. Checked. Reseated. Tried the reset button. Finally had no choice but to disable emmc. Fine. Boots again, but seems to corrupt the sdcard too. Bought a new sdcard in case this was the problem. Nope.

So I have a $200 paperweight and nothing to show for it. It won't reliably boot from sdcard (again, why is there no eject functionality?) and the emmc is seemingly useless. I cannot express how disappointed I am.

I tried to install Debian on my Pinebook Pro, because I don't really like Manjaro. I made the bootable SD with the Pinebook Pro build of Debian, booted into debian, and tried to write the debian disk image to the eMMC with gnome-disk-utility. I cleared all of the partitions before doing this, including the boot-manjaro partition. Perhaps that was my mistake, as now I can't boot at all, even with the SD card.

Is there any way to fix this?

Thanks!

Just received my Pinebook Pro last Thursday, like it a lot so far. Wondering if anybody knows how much vertical clearance there is between the CPU/WiFi/eMMC and the bottom panel. I've been looking around here for the last few days and I've seen some people talking about adding thermal pads to those parts of the board to help with performance (I've heard the WiFi module in particular can get toasty). I don't even know how I would go about measuring the clearance.
