| SSD Benchmarking on PBP |

I've recently received my new PBP. Before setting up a new system, I tend to benchmark things to see what it can do and spot out any issues. I thought it might be interesting to other readers to know my results, and I am sharing them here.
I'm using a PBP with a Kingston A2000 SSD. I was able to install it without issues and it is recognized on /dev/nvme0n1. I set the power level to 3 (sudo nvme set-feature /dev/nvme0 -f 2 -v 3) I created a gpt partition and formatted it as ext4.
In order to benchmark it, I disabled swap (sudo swapoff /dev/zram0) and then used dd to write/read a 8GB file (2x physical memory size) multiple times on the nvme partition.
My results are an average write of 395MB/s and an average read of 590MB/s. I'm very happy with this result as it is a very low power setting and about 10x faster than I could achieve on a microSD card with a samsung chromebook plus.

| Building Kernel App for fast GPIO |

Hello, I am quite interested in the Pine 64+ with the Gigabit ethernet.
For my project, I don't really need an OS, I'd be happy with a fast $20 Arduino with Gigabit ethernet,
but there is no such thing. I also need fast bootup, so don't really want an OS layer.
It looks like what I need to do is build a kernel and boot it from the flash drive,
and have it run my application. I need really fast access to the GPIO pins for some gigabit speed communication to devices.
Any help here appreciated, or if you can suggest other $20 gigabit speed hardware.
Thanks!
Jack

I am running Manjaro with Xfce. I try to update at least every two weeks. A few weeks ago I noticed I started getting quiet a bit of double letter errors when typing. The letter I notice this happening with the most is n but other letters will double up as well. I don't think it is from me pausing while typing. Has anyone else seen anything like this? Originally I thought it may have been something with one of the updates but I am wondering if it may be keyboard related.

Hi all,
I've just purchased my Pinephone with Manjaro installed on it by default. Later I flashed my SD card with Mobian Phosh so I can start Mobian now by default.
But, is there any way to choose the operative system I want when I turn on my Pinephone? Or, what can I do to start Manjaro again?
Thanks for answering.

| Swipes hardly recognized, is there a way to test touchscreen? |

Hi there,
I've just received my pinetime (sealed), and it's a neat device but it seems that the swipe is not recognized correctly. It's really difficult to change app, and when I'm launching the "paint game", it's unusable (pixel seems randomly printed). I can click buttons though, so the touch screen is more or less working. I've updated to infinitine 1.0 including boot and recovery following wiki instruction.
Is there an app/way to check if swipes are recognized correctly? Is there a way to calibrate or fix it somehow?
I've also tried to install wasp-os 0.4 (it's super neat to have a micropython console to your watch, great potential!), and I've tried snake to check the screen, it's absolutely impossible to play: I can't go down, and it's really hard to make it move in any of the other 3 directions. Is it working correctly for people here? If so, I'm afraid that my device has an hardware issue.
Thanks

| Shorted New Pinecil - Help please |

Hi Guys,
hands up, my fault.
In my haste to check my new Pinecil was working, and as cool as seen on You Tube. I quickly hooked up my bench supply, via a barrel connector with alligator clips, and powered it up.
Wasn't supposed to be on long, just a quick test... Long story short alligator clip slipped and... spark...
Didn't kill it. But decided to put it away until my new power supply 65W USB arrived, and a new USB C to USB C lead.
Powered up, but only in one orientation of the USB lead connection, and only on 9V...
Suspected lead at first, but testing on my son's charger and lead showed his Pinecil working fine on both chargers and both leads.. 20V negotiated no problem.
However, it also transpired that 12V 1.5A seems to work when in a different socket of the charger. Still lead would only work one way up.
Opened it up, everything seems OK, but apparent issue around C2 and CC2 connection on FUSB320MPX.
Which explained the lead only connecting in one orientation, and lead us to suspect the FUSB320.
Ordered up a new FUSB320 chip and some 220pF capacitors, and my son swapped them out with his SMD stuff...
Bitter sweet result, leads now connect in both orientations. But, will still only negotiate at 9V 3A, and 12V 1.5A. on the chargers.
Does anyone here have enough experience of the FUSB320 and or the Pencil to help identify what might be preventing the proper negotiation of the Pinecil...
Is there a hidden fuse?
would re-flashing fix it...?
It (touch wood) still works, heats up display is fine, but doesn't negotiate the power connection 'fully'....
Thanks for any help.
