I've been playing around with my new Lexar M.2 drive and while my results aren't by any means scientific, I thought they might still be of interest to others.  All of these observations are specific to this one drive, on my PBP, running the default OS.

Lexar bills the drive as "ideal for smaller notebooks" and "an entry-level PCIe NVMe", and so far I think the description fits.  The three active power options for the drive are:

PS 0: 3.05W
PS 1: 2.44W
PS 2: 2.02W

The full power state information returned by the drive to nvme-cli is:

Just a simpel unboxing for those who are curious.

Hi,
I seen a post somewhere that Sailfish is no longer supported. Is Nemo the OS that took over the open source portion of Sailfish?

I received my PinePhone (Braveheart Edition) and I was running postmarketOS on it yesterday (the OS on the SD Card). Now the device won't even turn on at all.

I had the device plugged into the charger all night and it still won't turn on. Is my phone no good already? If so, I want a refund because I expect my electronics to last more than a day.

Just for the record, I tried several things, such as putting the battery in and out, charging it (all night even) with different chargers (including the Nintendo Switch charger), I hit the Reset button on the back of the phone, etc.

What is going on here?

Is there any GUI to install printers in Manjaro? The ubuntu mate build detected our printer (epson wf-35200) fairly easily via the printers tab in settings, but Manjaro does not appear to have a single setting relating to printers. If it all possible, I really don't want to mess around with CUPS.

Has anyone noticed battery issues with UBPorts?  

I received my PinePhone and tried out UBPorts.  I did upgrade and update and played around a bit.  The phone was charged to 100%.  I locked the screen and went to bed.  In the morning the battery was completely dead. 

It appears the OS didn't go to sleep or something was running heavily enough to completely drain battery.

Does anyone have clear, specific instructions on how to install the updated uboot in manjaro? I tried to follow these instructions in the /boot file in manjaro:
flash_uboot() {
  echo "A new U-Boot version needs to be flashed onto your install drive. Please use lsblk to determine your drive, before proceeding."
    echo "You can do this by running:"
    echo "# dd if=/boot/idbloader.img of=/dev/mmcblkX seek=64 conv=notrunc"
    echo "# dd if=/boot/u-boot.itb of=/dev/mmcblkX seek=16384 conv=notrunc"
}

## arg 1:  the new package version
post_install() {
  flash_uboot
}

## arg 1:  the new package version
## arg 2:  the old package version
post_upgrade() {
  flash_uboot
}
but....the second dd command failed (never gave any visible output) and I temporarily bricked my PBP . I don't particularly want to repeat that experience EVER again, so I don't want to try it again until someone else gives it a good look over. Confusingly, I found these instructions printed in the terminal while doing pacman -Syyu:

(213/215) upgrading uboot-pinebookpro                [############################] 100%
warning: /boot/boot.scr installed as /boot/boot.scr.pacnew
warning: /boot/boot.txt installed as /boot/boot.txt.pacnew
A new U-Boot version needs to be flashed onto /dev/mmcblkX.
You can do this later by running:
# dd if=/boot/idbloader.img of=/dev/mmcblkX seek=64 conv=notrunc
# dd if=/boot/uboot.img of=/dev/mmcblkX seek=16384 conv=notrunc
# dd if=/boot/trust.img of=/dev/mmcblkX seek=24576 conv=notrunc
(214/215) upgrading xorg-server-common       

Thoughts/ideas??
P.S. I am running Manjaro from my emmc and did check to make sure I flashed the correct drive (the emmc)

Has anyone been able to build a Kali Linux image with the build script? I have tried very hard on both the pinebook pro and another laptop to run it, and I have run into a few obstacles: first, when I run it on the PBP on Manjaro, the ./build-deps.sh script fails because the script uses apt-get. Then, when I switched to Ubuntu Mate, I discovered that the PBP's cross-compiler does not seem to be compatible with arm (apt-get can't find the package). Finally, I switched to another (intel cpu) laptop running elementary os, installed the compiler, and ran the ./build-deps.sh script without issues. But when I tried to run:

If you accidentally soft brick your PBP there is special mode implemented called maskrom mode. In this mode the device is accessible as regular USB device and can be accessed using rkdevelop tools. Especially to rewrite SPI flash or to erase it.

According to Rockchip documentation it should be accessible following below procedure:

1. Press and hold recovery button.
2. Short press reset.
3. Release recovery button after about 3 seconds.

Unfortunately it is not always the case. I had a clear SPI from factory and had to do this procedure trillion times to eventually get into maskrom mode. There is another person who had the same problems.

The nature of this problem is not clear. There are two suspicions:

- the button is not working correctly or is just prone to failures.
- the problem occurs only when the SPI was previously flashed.

One way or the other the button works shorting two pins in an SPI device. But in some cases it just does nothing. So if you experience such problem there is a way to overcome it. You can short the two pins by yourself.

Procedure:

1. Unscrew bottom cover.
2. Remove the metal shield surrounding main CPU - it is held in place by a tape and micro clamps on pcb.
3. Disconnect all (!!!) boot devices (emmc, sdcard, usb).
4. Locate SPI flash (number 29 on picture).

5. Connect pbp with USB-C - USB-A cable to another computer (pbp on USB-C side).
6. Turn on pbp, short pins CLK and VSS and press reset. It should get your pbp into maskrom mode.

On another computer:

1. Compile rkdeveloptools --> https://github.com/rockchip-linux/rkdeveloptool

2. Create a file filled with zeros:
